WILLIMANTIC — The chief medical examiner office revealed this morning that the 30-year-old Willimantic man who was found unresponsive in his jail cell at the Willimantic Police Department early Thursday morning hanged himself.

Connecticut State Police spokesman Trooper Tyler Weerden identified the male as Matthew Mowrey of 136 Chapman St., Willimantic.

According to Willimantic police, Mowrey was found unresponsive at approximately 3 a.m.

“The Willimantic Police Department expresses our deep sympathy to the male individual’s family and friends,” Willimantic Police Chief Roberto Rosado said in a press release issued Thursday.

The chief medical examiner’s office said an autopsy was conducted on Mowrey on Thursday and they determined Mowrey committed suicide by hanging himself.

After determining Mowrey was unresponsive, Willimantic officers performed CPR on him.

EMS personnel responded and transported him to Windham Community Memorial Hospital, where he was later pronounced dead.

Police said the department requested assistance from the state’s attorney’s office in Danielson and from the Connecticut State Police Eastern District Major Crime Squad.

Rosado said in the press release the investigation was turned over to state police “in order to maintain transparency and have an independent investigation from an outside agency.”

Willimantic police said officers responded to a complaint in Willimantic at approximately 10:08 p.m. Wednesday. Mowrey was taken into custody on felony-related charges and brought to the police department.

According to state police, Mowrey received domestic violence charges, but the specific charges were unavailable.

Police said Mowrey was cooperative and officers did not use any physical force when taking him into custody.

According to police, he was placed into a cell Wednesday night. The cell was not occupied by anyone else, police said.
