A Maryland State Police investigation has concluded that Baltimore police Detective Sean Suiter died by suicide.

Baltimore Police Commissioner Michael Harrison released a statement, saying, "I have received the Maryland State Police report regarding their review of the investigation into Det. Sean Suiter's death. There is nothing in the report to suggest that Det. Suiter's death was anything other than a suicide, nor was there any suggestion that the case should be re-investigated or continued. Given that, and given similar findings by last year's independent review board, BPD’s investigation into Det. Suiter's death is now closed. Regardless of the circumstances, Det. Suiter's death was a tragedy and we will continue to keep him and his family in our thoughts and prayers. Finally, I want to thank Superintendent William Pallozzi and every member of the State Police who worked on the report for their commitment to bringing closure in this case."

State police announced in June that its homicide detectives would provide an investigative review of materials related to the Suiter case.

The Wednesday announcement comes a week before the two-year mark since Suiter was found shot in the head in November 2017 in a vacant lot on Bennett Place in west Baltimore. Suiter was to testify the day after his death before a federal grand jury in the Gun Trace Task Force corruption case.

The medical examiner ruled Suiter's death a homicide and an independent review concluded his death was a suicide.

Two weeks after Suiter's death, in December 2017, then-Commissioner Kevin Davis asked the FBI to take over the investigation. The FBI declined to do so.

Then-Mayor Catherine Pugh fired Davis and hired Darryl De Sousa as the new commissioner. De Sousa named an independent review board to review the case in April 2018.

Five months later, the Independent Review Board concluded Suiter killed himself. The report also accused Davis of misleading the public.

The board's report concluded, "Suiter was killed with his own service weapon in a vacant lot just west of 959 Bennett Place on Nov. 15, 2017."
