A Sidney man was killed early Monday morning when he crashed his motorcycle on North Belfast Avenue in Augusta.

Jacob Dufresne, 26, who was alone on the motorcycle, died at the scene of the crash, said Augusta Police Deputy Chief Jared Mills.

A passerby reported the crash around 5:15 a.m. Monday, but investigators believe the crash likely occurred earlier.

“There was some concern at the scene that he’d been there for a little bit based on the findings,” Mills said.

Investigators believe Dufresne was driving his 2001 Yamaha east on North Belfast Avenue when he skidded out of control at a slight turn in the road. Mills said the motorcycle crossed into Hidden Haven Lane and Dufresne was thrown from the motorcycle.

“It looks like he continued straight onto Hidden Haven Lane,” Mills said.

Dufresne, who was wearing a helmet, ended up in a ditch, but there were no obvious signs that he hit anything.

“It appears the injuries were caused by being ejected from the bike,” Mills said.

Dufresne’s blood will be tested for intoxicants, which is standard for crashes involving serious injury or death.

“Initial indications are that speed was a factor,” he said.

Mills said investigators know of no witnesses to the crash. He asked anyone with information to call Officer Brett Lowell at 626-2370 ext. 5020.
