A current sergeant and former lieutenant for the Massachusetts State Police have been named as the subjects of an ongoing criminal investigation in connection with another trooper’s role in a fatal 2023 crash.
Lt. Anthony DeLucia and Sgt. Mark Delaney were both referred to as “subject[s] of criminal investigation” in a motion filed Monday by a Middlesex Superior Court judge. No charges had been filed against them as of Tuesday night.
In March, Sgt. Scott Quigley was indicted on a motor vehicle homicide charge. Prosecutors allege that, on Dec. 12, 2023, he was driving under the influence when his unmarked cruiser crossed into oncoming traffic and struck another vehicle, killing Angelo Schettino, 37.
Quigley pleaded not guilty at his April 15 arraignment and was released on personal recognizance. He is due back in court in August, records show.
The allegations that Quigley was intoxicated at the time of the crash didn’t surface until January 2026, when prosecutors disclosed information that he was being investigated to the judge presiding over the murder trial for brothers Billoeum Phan, Billy Phan, and Channa Phan. The Phan brothers are alleged to have murdered Tyrone Phet in Lowell on Sept. 14, 2020.
Quigley investigated the Phan case and was scheduled to appear as a witness in the trial, but his own legal issues and the ensuing allegations have resulted in the murder trial being repeatedly delayed.
The Phan trial was initially scheduled to proceed April 27, but since Quigley’s indictment has complicated matters, the start date is now in limbo. Confirmation that DeLucia and Delaney are involved in a criminal investigation came from a June 29 finding rejecting the Phan brothers’ motion to dismiss the indictments against them, citing prosecutorial misconduct.
“The Quigley Misconduct and State Police Misconduct information is possible impeachment evidence, conceivably admissible to undermine the credibility of Sergeant Quigley or another State Police witness if they testify at trial,” Judge Christopher Barry-Smith wrote in the ruling. “The late-disclosed information does not concern the investigation of Defendants or the September 2021 [sic] shooting of Tyrone Phet, and does not directly impact the Commonwealth’s proof in this case.”
A subsequent independent investigation by the Middlesex County District Attorney’s Office indicated that DeLucia had reason to believe that Quigley was intoxicated long before any allegations came to light. DeLucia allegedly told Scott Sarsfield, the DA’s director of operations and security “in the spring or summer of 2024” that Quigley “was a ‘0.11,’” which Sarsfield took to mean his blood alcohol level.
After DeLucia disclosed this information to Sarsfield, he allegedly told him not to repeat that information. On Feb. 12, after court disclosures indicating that Quigley may have been intoxicated were released, DeLucia allegedly said to Sarsfield, “what we had talked about, take that to the grave.”
Sarsfield later documented the details of the 2024 conversation in a handwritten note to the retired Superior Court judge leading the DA’s investigation. He clarified that he never shared what DeLucia had told him because he presumed that “the proper notifications had been made and that anyone who needed to know was informed.” He only told his supervisors what he knew once the allegations against Quigley became public.
On April 1, the same day that the DA’s office released their report, DeLucia was suspended with pay. In the following weeks, he retired from State Police and was dishonorably discharged, MassLive reported.
Delaney was not mentioned in the DA’s report, and the extent of his involvement in the Quigley investigation was not specified in Monday’s motion. However, the filing identified him as a “subject of criminal investigation” and noted that State Police placed him on “restricted duty.”
Following Quigley’s indictment, he was suspended by the Massachusetts Peace Officer Standards and Training (POST) Commission. His law enforcement certification was revoked on the grounds that he “engaged or may have engaged in criminal conduct,” his suspension order states.
