PITTSFIELD -- The woman who was thrown from a motorcycle Tuesday afternoon has died from the injuries she suffered in the accident.

Kimberly E. Deming, 23, of Pittsfield, died at Berkshire Medical Center Wednesday after the 2005 Harley-Davidson motorcycle she was riding on went off the road. It was operated by Martin Layton.

The accident occurred at around 3:30 p.m. Tuesday, according to police, as Layton and Deming traveled southbound on Jason Street in the 80 block.

Layton lost control of his motorcycle, causing it to strike the west side of the curb and guardrail, police said.

Both riders were thrown from the motorcycle, but Layton was not injured. No details have emerged about the accident, which remains under investigation.

Deming, who has two sons, was a Mount Everett Regional High School graduate. She had completed the Certified Nursing Program at Berkshire Medical Center and worked for a short stint at Berkshire Meadows in Housatonic.

The motorcycle crash wasn't the only serious accident this week.
