A key witness agrees to talk, then disappears. Emails go unanswered. A promised list of available times never arrives. Meanwhile, the investigation clock keeps running, and the parties wait for an answer.
A nonresponsive witness can complicate an investigation, but it does not automatically bring the process to a stop. The investigator’s job is to make reasonable efforts to obtain the information, protect the employee’s rights, gather the best evidence available, and explain any limits in the final findings. The following are some recommendations both for investigators and for those agency employees charged with coordinating the investigation.

Before determining a witness “uncooperative,” try to find out whether the problem is practical, legal, or personal. The witness may be on leave, working a different schedule, worried about retaliation, unsure whether the interview is mandatory, or waiting for a union representative. A former employee or outside witness may simply have little incentive to respond.
One clear, respectful message can often solve the problem. Identify the investigator, explain the subject in neutral terms, state that the person may have relevant information, offer reasonable scheduling options, and provide a deadline to respond. Avoid promising complete confidentiality or that the interview is “necessary” for the investigation to be completed. Instead, when asked, generally respond that information will need to be shared on a need-to-know, confidential basis, and only to the extent reasonably necessary to investigate and respond to the complaint.

There is no universal number of contact attempts that makes an investigation “complete.” The right approach depends on the importance of the witness, the urgency of the allegations, agency policy, applicable labor agreements, and the reason for the delay. A practical sequence may look like this:
A. Make the first request easy to answer. Offer several dates, a remote option, and a direct way to identify any accommodation, leave, or representation issue.
B. Follow up in writing. If the witness does not respond, send a concise reminder with a reasonable deadline. Keep a record of each attempt, the method used, and any response.
C. Clarify whether participation is expected. For a current employee, the agency may be able to issue a lawful work directive to attend and answer questions, depending on its policies, labor agreements, and the employee’s status. The investigator should coordinate with Human Resources or counsel before threatening discipline for noncooperation.
D. Set and communicate the stopping point. Tell the witness when the investigator will proceed without the interview if there is no response. That creates a fair and final opportunity while keeping the matter moving.

A person who begins as a witness may become a possible subject as facts develop. For represented public employees, questioning may trigger a right to union representation when the employee reasonably believes the interview could lead to discipline and asks for a representative. If the interview changes direction, pause and reassess instead of pushing ahead under the original “witness” label.
Additional rules apply to peace officers and firefighters when an interview could lead to punitive action. The Firefighters Procedural Bill of Rights Act and the Public Safety Officers Procedural Bill of Rights Act both address matters such as notice, timing, recording, representation, and the consequences of refusing to answer job-related questions. Agencies should confirm the correct procedure before issuing a directive or characterizing a refusal as insubordination.

If reasonable efforts do not secure the interview, the investigator can turn back to the evidence map. The investigator can ask what the witness was expected to prove or disprove, then look for other sources: emails, texts, chat messages, calendar invitations, access logs, video, photographs, policies, work records, prior statements, or other people who observed the event or its aftermath.

The report should state, neutrally and accurately, the efforts made to contact the witness, any reason given for not participating, and whether the missing information limited the analysis. It should distinguish between “unsubstantiated” and “unable to determine” when agency policy uses those terms, and it should avoid speculation about what the witness would have said.
An investigation does not have to be perfect to be fair. It should be prompt, thorough, impartial, and reasonable under the circumstances. When the record is sufficient, the investigator should make findings and close the matter. When the missing interview truly prevents a reliable finding, the report should say so and identify any follow-up that may be appropriate if new evidence later becomes available.

Agencies can reduce delay by adopting investigation procedures that explain who must cooperate, how interview requests will be delivered, when representation may be requested, how leave and accommodation issues will be handled, and how noncooperation will be documented. Clear rules make it easier to act consistently when a difficult situation arises.
