How to Contact Someone Who Has Been Relocated Under Witness Protection: U.S. Marshals WITSEC Intermediated Communication Procedures
The U.S. Marshals Service operates the federal Witness Security Program (WITSEC) under 18 USC §3521 et seq., providing relocation and protection for witnesses whose testimony in federal proceedings creates serious threats to their safety. Direct location of WITSEC participants is impossible by design and prohibited by federal law. The proper channel for any communication with a WITSEC participant is Marshals-intermediated communication through specific authorized procedures.
The U.S. Marshals Service operates the federal Witness Security Program (commonly called WITSEC) under 18 USC §3521 et seq., providing protection and relocation for witnesses whose testimony in federal proceedings creates serious threats to their safety. The program traces back to the Organized Crime Control Act of 1970 and has protected over 19,000 witnesses and their families since inception. Participants in WITSEC receive new identities, new locations, employment assistance, and ongoing protection. The program’s continued effectiveness depends on absolute confidentiality of participant identities and locations — disclosure of WITSEC information can place participants in mortal danger.
Direct location of WITSEC participants by third parties is fundamentally impossible by design. The program structures identity changes, relocation, and ongoing protection specifically to defeat third-party location attempts. Standard skip tracing methodology does not reach WITSEC participants — credit-header data, Social Security records, employment records, and other typical investigation sources are managed within the WITSEC framework to protect participant identity. Practitioners attempting to locate WITSEC participants will not succeed through standard methodology, and attempting to do so is specifically prohibited by federal law with serious criminal penalties including federal prison sentences.
The proper channel for any legitimate communication with a WITSEC participant is Marshals-intermediated communication through specific authorized procedures. The U.S. Marshals Service maintains procedures for: (1) service of legal process on WITSEC participants for legitimate legal matters; (2) family emergency communications including medical emergencies and family deaths; (3) child custody and family law proceedings involving WITSEC participants; (4) certain civil litigation involving WITSEC participants; and (5) other specifically authorized communications. The intermediated procedures protect participant identity while supporting legitimate communication needs. This guide covers the proper procedures and explains why no other approach can or should be attempted.

💡 There is exactly one path: U.S. Marshals intermediation
The U.S. Marshals Service is the sole authorized channel for any communication with WITSEC participants. Service of legal process, family emergency communications, and authorized civil matters are coordinated through Marshals procedures that protect participant identity while supporting legitimate purposes. There is no skip tracing methodology that reaches WITSEC participants, no investigative service that can locate them, and no technology that can defeat the program protections. Attempts to circumvent the framework — investigation, hiring third parties, social engineering, payment for information — are federal crimes with serious penalties. The proper procedure is straightforward; the improper alternatives produce federal criminal liability without producing the desired result.
Need to communicate with a WITSEC participant?
The proper procedure is U.S. Marshals intermediation. Contact your attorney to coordinate legal matter communication, or contact the U.S. Marshals Service directly for family emergency channels. Professional skip tracing cannot and will not assist in WITSEC participant location.
The Witness Security Program under 18 USC §3521 et seq.
WITSEC was established under the Organized Crime Control Act of 1970, with the current federal framework in 18 USC §3521 et seq. The program is administered by the U.S. Marshals Service through the Witness Security Division. Participation in WITSEC requires specific eligibility findings: a witness must be testifying or have testified in a federal proceeding (most commonly federal criminal trials of organized crime, drug trafficking, or terrorism cases); the testimony must create serious threats to the witness’s safety; the U.S. Attorney’s Office must request witness security; and the Department of Justice must approve participation.
Identity changes and relocation
WITSEC participants receive new identities including: new legal names; new Social Security Numbers; new state identification documents; new employment history when needed for credibility; relocation to a new geographic area unknown to threats; and ongoing identity protection. The identity changes are integrated with state and federal record systems through specific authorized procedures protecting the new identity from disclosure.
Protection scope
WITSEC protection extends to immediate family members of the witness when family safety is also at risk. Spouses and children typically receive identity changes and relocation along with the witness. Adult family members can choose program participation or remain in their original identity (most choose participation when serious threats exist). The protection is comprehensive — typical WITSEC participation provides identity protection that withstands sophisticated investigation attempts.
Ongoing supervision
WITSEC participants remain under U.S. Marshals supervision throughout their program participation. The Marshals coordinate identity maintenance, relocation if threats reappear, and various life-event procedures including medical care, employment, and legal matters. Participants typically maintain WITSEC status indefinitely; some leave the program voluntarily after threat circumstances change, but most maintain protection throughout their lives.
Program effectiveness
The program has been operationally effective since inception. The U.S. Marshals Service reports zero successful identity compromises of compliant WITSEC participants in the program’s history. The effectiveness reflects the comprehensive identity-change procedures, ongoing supervision, and federal-level resource investment. Threats to WITSEC participants have generally been defeated by program protections; participants who maintain compliance with program rules generally maintain effective protection.
The structural impossibility of WITSEC location
Standard skip tracing methodology does not reach WITSEC participants because the program specifically defeats the methodology. Each typical investigation source has been addressed within the WITSEC framework:
Credit-header and credit reporting data
Credit-header data and credit reports for WITSEC participants are managed through specific authorized procedures within the program. Direct queries against the original identity will not find current location; queries against the new identity (which the inquirer does not know) cannot be constructed. The credit-data infrastructure does not provide a path to WITSEC participant location through any normal channel.
Social Security and federal records
WITSEC participants receive new Social Security Numbers integrated with federal record systems. The original SSN is generally maintained for historical purposes but does not link to current activities or locations. Federal record searches against the original identity find historical information only; the current activity is conducted under the new identity unknown to investigators.
State records (DMV, voter registration, real property)
State records for WITSEC participants under their new identity are integrated with state systems through specific authorized procedures. The records exist but are not searchable through the original identity. The new identity records exist but are protected from cross-referencing with the original identity through program-administered procedures.
Social media and online presence
WITSEC participants typically establish minimal online presence under new identities to avoid generating searchable digital footprint linkable to original identity. Social media activity, email accounts, online accounts associated with original identity are typically discontinued; new accounts under new identity are operationally separated. Reverse-image searches and similar visual-identification techniques are addressed through ongoing identity-protection procedures.
Family member contacts
Family members of WITSEC participants who remain in the original location receive specific guidance about communication with relocated relatives. Family members typically have no direct contact with relocated relatives outside Marshals-intermediated procedures. Attempts to reach WITSEC participants through family member intermediaries generally fail because family members either don’t know current information or recognize the importance of program compliance.
The cumulative effect is that no skip tracing methodology — professional or otherwise — produces WITSEC participant location. Practitioners offering services that promise WITSEC participant location are either misunderstanding the program (inability to deliver), making false claims (fraud), or attempting illegal activity (federal crime). No legitimate professional service can deliver WITSEC participant location.
Legitimate channels through U.S. Marshals procedures
The U.S. Marshals Service provides intermediated communication procedures supporting legitimate communication needs while protecting participant identity. The procedures are the sole authorized channel for any communication with WITSEC participants by parties outside the program.
Service of legal process
Civil litigation involving WITSEC participants requires service of process through Marshals coordination. The procedure: contact the U.S. Marshals Service Witness Security Division identifying the legal matter and the WITSEC participant (typically by original identity or by case reference if known); provide complete service-of-process documentation per Federal Rules of Civil Procedure; coordinate service through Marshals procedures. The Marshals arrange service through procedures protecting participant identity while providing FRCP-compliant service documentation.
Family medical emergency
Family medical emergencies (serious illness or death of family member, medical condition affecting participant directly) can be communicated through Marshals procedures. The procedure: contact the U.S. Marshals Service identifying the family relationship and the emergency nature; provide documentation of the medical emergency; coordinate communication through Marshals procedures. The Marshals evaluate the request and facilitate communication when the circumstances justify the contact.
Child custody and family law
Child custody, divorce, and family law proceedings involving WITSEC participants require specific Marshals coordination. The procedure depends on whether the participant is petitioner or respondent in the proceedings, whether the proceedings can be conducted with continued WITSEC protection, and various case-specific factors. Family law attorneys with WITSEC-related cases work directly with Marshals through specific Witness Security Division procedures.
Authorized civil matters
Some civil matters (estate proceedings, certain debt collection, certain regulatory matters) qualify for Marshals-intermediated communication. The qualification depends on the matter’s legitimacy, the available alternative procedures, and program-specific factors. The Marshals evaluate requests case-by-case and facilitate communication when the matter qualifies for the intermediation procedures.
Contact for WITSEC-related communication: U.S. Marshals Service, Witness Security Division. The general U.S. Marshals contact at https://www.usmarshals.gov/contact-marshals provides initial routing for WITSEC-related inquiries. For active legal matters, contact your attorney to coordinate the Marshals intermediation procedures appropriate to your specific case.
Federal penalties for WITSEC interference
Federal law specifically prohibits various attempts to locate or interfere with WITSEC participants. Attempts to circumvent the program’s identity-protection procedures produce serious federal criminal liability.
Witness tampering — 18 USC §1512
18 USC §1512 prohibits various forms of witness tampering including attempts to influence, intimidate, or harass federal witnesses. Attempts to locate WITSEC participants for purposes of intimidation or interference with their cooperation are clear violations producing federal criminal liability with sentences up to 20 years (or life imprisonment for cases involving murder or attempted murder).
Obstruction of justice — 18 USC §1503
18 USC §1503 prohibits obstruction of justice including various forms of interference with federal proceedings. Attempts to compromise WITSEC protection for purposes of interfering with ongoing federal proceedings are violations producing federal criminal liability. The penalties depend on case-specific factors but generally include substantial federal prison sentences.
Conspiracy and accessory liability
Conspiracy and accessory statutes (18 USC §371, §1001, §3) extend liability to parties who facilitate WITSEC interference even without direct participation. Practitioners who provide investigation services facilitating WITSEC interference, parties who pay for such services, and intermediaries who facilitate the activity all face conspiracy and accessory liability. The accessory framework specifically reaches investigators and skip tracers who provide services in WITSEC contexts knowing the protective program status.
Civil and administrative consequences
Beyond criminal liability, WITSEC interference produces civil and administrative consequences including: license revocation for licensed investigators, attorneys, and other regulated professionals; civil liability for damages caused by program compromise; administrative sanctions including federal contractor debarment; and various other consequences. The cumulative legal exposure makes WITSEC interference a uniformly bad professional decision regardless of any other factors.
⚠️ No legitimate purpose justifies bypassing the framework
Some inquirers ask whether their specific purpose justifies non-Marshals investigation. The answer is uniformly no — federal law does not provide exceptions to the WITSEC protection framework based on inquirer purpose. Even legitimate civil matters (debt collection, family communication, business disputes) must use the Marshals intermediation procedures rather than alternative investigation channels. The framework supports legitimate communication needs through Marshals coordination; bypassing the framework is criminal regardless of the underlying purpose.
What to do when you need to reach a WITSEC participant
If you have a legitimate reason to communicate with someone who you believe may be in WITSEC, the following framework provides the proper procedure:
Confirm the WITSEC status
Begin by confirming that the subject is actually in WITSEC rather than simply unreachable. Many subjects who become unreachable have moved, changed names through normal court procedures, or otherwise made themselves difficult to locate without being in formal witness protection. Standard skip tracing investigates these subjects effectively. WITSEC participation is relatively rare (under 20,000 program participants in the program’s 50+ year history) — most unreachable subjects are not in WITSEC.
Engage appropriate counsel
For legal matters involving suspected WITSEC participants, engage attorneys familiar with the federal framework. Defense attorneys who have practiced in federal organized crime, drug trafficking, or terrorism cases often have working knowledge of WITSEC procedures and can coordinate with Marshals on case-specific matters. Civil attorneys handling family law, estate, or business matters with potential WITSEC implications should engage co-counsel with WITSEC familiarity.
Contact U.S. Marshals through proper channels
For matters that qualify for Marshals intermediation, contact the U.S. Marshals Service through the appropriate channel. The general contact at https://www.usmarshals.gov/contact-marshals provides initial routing. For active legal matters, your attorney coordinates the specific Witness Security Division procedures. The Marshals evaluate requests and facilitate appropriate intermediation when the matter qualifies.
Accept the framework limitations
Some communications are simply not available through any framework. Marshals intermediation supports legitimate legal matters and family emergencies but does not support every conceivable communication need. Routine family communication, casual contact, business networking, and various other non-essential contacts are generally not facilitated through Marshals procedures. The framework limitations reflect the program’s protective design — comprehensive participant protection requires limiting communication channels even at the cost of routine convenience.
Common questions
Can I find someone who is in witness protection?
No. Direct location of WITSEC participants is impossible by design and prohibited by federal law. The program specifically defeats standard skip tracing methodology through identity changes, integrated record protection, and ongoing supervision. Attempts to bypass the framework are federal crimes producing serious penalties. The proper procedure for any legitimate communication is U.S. Marshals intermediation through specific authorized procedures.
How do I serve legal papers on someone in WITSEC?
Through U.S. Marshals coordination. Contact the U.S. Marshals Service Witness Security Division identifying the legal matter and the WITSEC participant (by original identity or case reference). Provide complete service-of-process documentation per Federal Rules of Civil Procedure. The Marshals arrange service through procedures protecting participant identity while providing FRCP-compliant service documentation.
What if I have a family medical emergency?
Contact U.S. Marshals through standard channels identifying the family relationship and the emergency nature. Provide documentation of the medical emergency. The Marshals evaluate the request and facilitate communication when circumstances justify the contact. Family medical emergencies are a recognized basis for Marshals intermediation.
Can my attorney help me reach someone in WITSEC?
Yes, through Marshals coordination procedures. Attorneys familiar with federal framework can coordinate with the U.S. Marshals Witness Security Division on case-specific matters. Defense attorneys with federal organized crime, drug trafficking, or terrorism case experience often have working WITSEC procedure knowledge. Family law and civil attorneys with WITSEC-related cases typically engage co-counsel with relevant familiarity.
What if a private investigator says they can find someone in WITSEC?
Either misunderstanding the program (cannot deliver), making false claims (fraud), or attempting illegal activity (federal crime). No legitimate professional service can deliver WITSEC participant location. Practitioners offering such services should be reported to state licensing authorities and federal law enforcement. The fees paid for such services are typically not recoverable; the practitioner exposure includes federal criminal liability.
What are the penalties for trying to find a WITSEC participant?
Federal criminal penalties under 18 USC §1512 (witness tampering, up to 20 years or life), 18 USC §1503 (obstruction of justice, substantial federal prison sentences), and conspiracy/accessory statutes (extending liability to facilitators). Civil and administrative consequences include license revocation, civil liability for damages, federal contractor debarment, and various other professional consequences.
How do I know if someone is in WITSEC?
Generally you do not know with certainty unless the participant or law enforcement specifically discloses the status. Subjects who suddenly become unreachable, change identities through unusual procedures, or display various other indicators may be in WITSEC — but many other explanations exist for the same indicators. Most unreachable subjects are not in WITSEC; standard skip tracing addresses most cases effectively.
Can I contact a WITSEC participant about a debt?
Through Marshals coordination if the matter qualifies for intermediation. Some civil debt matters qualify; others do not. The Marshals evaluate requests case-by-case and facilitate communication when the matter qualifies. Debt collection through alternative channels (credit-header investigation, employer searches, asset discovery) does not work for WITSEC participants and is prohibited under the federal framework.
What if WITSEC participation has ended?
Some participants leave WITSEC voluntarily after threat circumstances change. Post-WITSEC subjects may be findable through standard skip tracing methodology after they leave the program. The transition is participant-controlled — the U.S. Marshals do not generally announce program departures. Post-WITSEC subjects who choose to be findable typically establish public-record presence under their post-program identity that supports standard investigation.
What about state witness protection programs?
Several states operate state-level witness protection programs separate from federal WITSEC. State programs vary in structure and protection scope. Communication with state-program participants is generally coordinated through the state agency administering the program rather than the U.S. Marshals. The principles are similar — direct investigation does not work, intermediated communication through proper channels does.
The proper procedure is U.S. Marshals intermediation.
Contact your attorney to coordinate legal matter communication, or contact the U.S. Marshals Service directly for family emergency channels. Professional skip tracing cannot and will not assist in WITSEC participant location.
