LOWELL -- The Police Department's Board of Inquiry investigation examining the actions of three detectives who have been on paid administrative leave for potential inconsistencies with evidence is complete, according to officials.

However, the contents of the Board of Inquiry report remain private because they relate to an ongoing federal investigation, which "could be jeopardized by the release of this report," Lowell Police Capt. James Hodgdon said in a statement Friday afternoon.

Three detectives from the Special Investigation Section have been on paid administrative leave during the Board of Inquiry investigation. The Sun has learned those detectives are Nicholas Dokos, Rafael Rivera and David Lavoie.

The Board of Inquiry's formation came as a result of information received from the Middlesex District Attorney's Office. The case involves a fentanyl and gun arrest from March.

Paul Aaron was arraigned in Lowell District Court on March 8 on charges of trafficking in fentanyl over 10 grams, four counts of possession of a large-capacity firearm/feeding device, trafficking over 200 grams of heroin, possession of a firearm during the commission of a felony, wearing body armor during the commission of a felony, possession of a firearm without an FID card, possession of ammunition without an FID card, and two counts of improper storage of a firearm.

The narcotics charges were subsequently presented to a federal grand jury by the United States Attorney's Office.


While the case was pending, new information came to light regarding potential inconsistencies in the evidence. As a result, the Middlesex District Attorney's Office decided not to prosecute "in the interest of justice," the office said in a statement. That information was referred to Lowell Police Department, which then formed the Board of Inquiry.

The board's investigation is complete, but the federal drug charges against Aaron are proceeding in U.S. District Court after Aaron rejected a plea deal.

"... if the requested report were released, confidential investigative techniques, procedures or sources of information could be disclosed and the identity of suspects or witnesses could become public knowledge," Hodgdon said in a statement. "The release of the requested report at this time could alert the public to what specific knowledge, leads, etc. that investigators have, or do not have. Therefore, disclosure of the requested report could prejudice effective law enforcement efforts."
