Criminal Defense Investigation Across Massachusetts
A criminal defense investigation builds the factual side of a defense case: locating and interviewing witnesses the prosecution didn’t call, re-examining the scene, checking timelines and alibis against phone and location records, and finding evidence that a defense attorney needs but doesn’t have the time or resources to chase down personally.
We work at the direction of defense counsel, not independently of them — findings go into the case file as work product, and every interview follows the same disclosure and consent rules as any other investigation under Massachusetts law (M.G.L. c. 272, §99 on two-party consent). As a licensed investigative firm (License #LP0203L), our reports and testimony, if needed, are built to withstand cross-examination.
- ✓Witness canvassing and interviews, including witnesses the prosecution didn’t call
- ✓Scene re-examination and photo/video documentation
- ✓Timeline and alibi verification against phone records, receipts, and location data
- ✓Records research to surface evidence favorable to the defense
- ✓Reports formatted for direct use in discovery and case preparation
Working at Defense Counsel’s Direction
We take direction from the defense attorney on record and keep them informed throughout — this isn’t freelance investigation outside the case strategy. If a lead takes the investigation somewhere counsel didn’t anticipate, we flag it rather than chase it unilaterally, since timing and disclosure obligations in a criminal case are counsel’s call, not ours.

Have your attorney reach out directly, or call us and we’ll loop them in. Every case starts with a scope conversation, not an open-ended retainer.
Common Questions
Do you only work on Massachusetts cases? Our license covers Massachusetts; for a case elsewhere, talk to us and we’ll tell you honestly whether we can help or whether local counsel needs an investigator licensed in that state.
Can an investigator testify at trial? In some cases, yes — if findings become relevant testimony, your attorney will make that call, and we prepare documentation with that possibility in mind from the start.
Defense investigation work is conducted under the same Massachusetts private investigator licensing requirements that cover all of Hub’s investigative services, and every finding is documented to the standard defense counsel needs if it ends up supporting a motion or trial testimony.
Defense investigators often work against a tight court calendar, which is why Hub treats witness location and interview scheduling as time-sensitive from the first phone call rather than something to get to eventually — a lead that goes cold while waiting is a lead counsel may not get a second chance at.
What a Hub Criminal Defense Investigation Report Looks Like
Below is a shortened, fictional sample report in the same format our investigators deliver to defense counsel.
HUB SECURITY AND INVESTIGATIVE GROUP
Defense Investigation Report — Sample (Fictional)
Case #: SAMPLE-8019 Date: 02/06/2026 Investigator: T. Marsh
Summary of Findings: Retained by defense counsel to locate and interview two potential witnesses named in the police report. One witness was located and provided a signed statement that differs from their account summarized in the police narrative regarding the sequence of events. The second witness could not be located at the listed address; a current address was independently identified through records research and forwarded to counsel.
Recommendation: Counsel to evaluate the witness statement obtained and determine whether formal process is warranted for the second witness.
This is a fictional sample created to illustrate our reporting format — the dates and case details shown are not real.
Defense work is documented the same way every time: who was contacted, what they said, and how it was verified, so counsel can rely on it.
