The Role of a Private Investigator in a Massachusetts Criminal Defense Case

When facing criminal charges in Massachusetts, building a strong defense requires more than legal knowledge—it also relies on uncovering facts, challenging assumptions, and verifying every detail of the prosecution’s claims. Private investigators often play an important role in this process. Their ability to gather information, locate witnesses, and analyze evidence can significantly influence the outcome of a case.


At Brian D. Roman, Attorney At Law, we can provide legal assistance to the North Attleborough community and understand how the strategic use of a private investigator can strengthen a defense from the very beginning.


Why Private Investigators Are Valuable in Criminal Defense


A private investigator works alongside the defense attorney to uncover information that may not appear in police reports or witness statements. Their involvement can help ensure that the defense has a full and accurate picture of what truly occurred.

Key areas where a private investigator contributes include:


1. Independent Evidence Collection


Police investigations often focus on building a case for the prosecution. A private investigator, however, conducts an independent review aimed at identifying alternative explanations or overlooked evidence. They may gather surveillance footage, photographs, physical evidence, or digital data that supports the defense.


2. Witness Interviews and Location Efforts


Witness testimony can shape the direction of a criminal case. Investigators locate witnesses who have not yet come forward or whose accounts differ from the prosecution's narrative. They interview individuals, take statements, and help verify or contradict witness claims.


3. Reviewing Law Enforcement Procedures


A private investigator can look into whether police followed proper protocol during the arrest, search, or evidence collection. Any procedural violations may be used to challenge the charges or suppress improperly obtained evidence.


4. Background Research


Investigators conduct thorough research on witnesses, alleged victims, or other involved parties. Their findings may reveal motives, inconsistencies, or credibility concerns that the defense can use in court.


5. Trial Preparation and Support


Private investigators assist attorneys by organizing evidence, preparing exhibits, and sometimes testifying in court about their findings.


How Working With a Private Investigator Supports the Defense


When attorneys collaborate with skilled investigators, they gain access to deeper insight into the case. This allows the defense to challenge the prosecution’s version of events more effectively and present a more detailed, fact-based argument.
