Police have arrested a second suspect in the death of a Waldoboro man after they say he led them on a chase through the Augusta area Tuesday and barricaded himself inside his vehicle.

Jason Hewett, 39, of Augusta, was arrested after four hours of negotiations and is charged with manslaughter, domestic assault and eluding an officer, Maine State Police announced Wednesday morning.

Police say Hewett is a suspect in the death investigation in which another man has already been charged. But little else has been released about the circumstances of the death.

Mark Gagne, 41, was arrested late last week on charges of abuse of a corpse and hindering apprehension in connection with an investigation into a death.

According to court documents for Gagne obtained by the Courier Gazette, prosecutors identified the victim as Kyle MacDougall, 45, of Waldoboro. State police confirmed MacDougall’s identity Wednesday afternoon.

It’s unclear when MacDougall died, but Gagne has been accused of digging up, removing, concealing or destroying a human corpse or its ashes on July 12, and trying to prevent the arrest of the person who caused the death, according to court records.

A probable cause affidavit, which would detail the case and the reasons for Gagne’s arrest, has been sealed. Gagne’s bail was set at $100,000. He also has two active no-contact orders and his next court hearing is set for Sept. 5.

Waldoboro police Chief John Lash said Wednesday there was no missing persons report filed for MacDougall locally.

“I found out on the news like everyone else,” Lash said.

Lash said that his department wasn’t involved in the investigation and the murder didn’t happen in Waldoboro.

Hewett, who court records show also uses the last name Goucher, was arrested after a chase with Maine State Police that began around 2 p.m. Tuesday on Route 32 in Windsor, according to Department of Public Safety spokesperson Shannon Moss. Hewett took Route 3 in Augusta and, in an effort to avoid spike mats, drove into a ditch and onto the lawn of Nadeau Chiropractic and Wellness Center, where he then barricaded himself inside his vehicle.

The situation closed the heavily traveled Route 3 in Augusta for several hours. Hewett was eventually taken into custody and brought to the Kennebec County Correctional Facility in Augusta.

Both Hewett and Gagne have lengthy criminal records, according to background checks through the Maine Bureau of Identification.

Hewett has spent much of the last 20 years in and out of jail. His most serious charges include drug trafficking, assault, forgery, burglary and repeatedly driving under the influence and on a suspended license. Many of his most serious charges were incurred while he was in state prison, including one of his drug charges.
