Augusta’s Police Chief Robert Gregoire remains hospitalized with critical injuries after crashing his motorcycle Saturday during an off-duty charity ride.

Gregoire, 49, was in critical condition at Central Maine Medical Center in Lewiston, a hospital spokeswoman said Monday morning.

His wife, Cathy Gregoire, 47, who was a passenger, has been released from the hospital.

A third person, Augusta Police Sgt. Christopher Shaw, 45, who was riding a second motorcycle, also was taken to Central Maine Medical Center. He, too, has since been released from the hospital, according to the spokeswoman.

All three were hurt around 4:30 p.m. Saturday during an accident on Crash Road in Jay.

The Jay Police Department couldn’t be immediately reached Monday for comment. Sgt. Troy Young of the Jay Police Department told the Lewiston Sun Journal that Gregoire’s Harley crashed and Shaw, who was also riding a Harley, and was unable to avoid the downed motorcycle. Young said rain may have contributed to the crash.

Young said none of the injuries appeared life threatening. Both motorcycles, which are personal vehicles, sustained heavy damage, Young said.

Barry Gates, who helped organize the Kora Kare for Kids Ride-In in Jay, said the Gregoires and Shaw were with a group of riders to the Rangeley area and were returning to the ride field at Twitchells Airport in Turner when the crash occurred.

He said both Gregoire and Shaw, who serves as a motorcycle patrolman for the department, are experienced riders.

“It was just an unfortunate accident,” Gates said.

Gates said other riders stayed to help the Gregoires and Shaw until rescue arrived. A couple of people from the event went to the hospital to see if they could help, Gates said.

“We’re still trying to stay in contact,” he said. “We want to do anything we can to help the families.”

The third annual ride is a fundraiser for the Shriners Hospitals for Children, which primarily treats children who suffer burns. Gates said rain storms held off until late in the afternoon, but still impacted the turnout, which was less than what organizers would have hoped. The crash brought the ride to a premature conclusion.

“They were participating in a great fund raiser for those hospitals,” Gates said. “It’s very unfortunate and we feel bad about it and we hope we can help however we can.”
