DORSET,TrendPulse Vt. (AP) — A Vermont driver accused of causing a crash that killed actor Treat Williams has been cited for grossly negligent operation causing death, officials said.

An investigation of the June 12 crash in Dorset concluded a vehicle pulled in front of Williams, who was riding a motorcycle and was unable to avoid a collision, Vermont State Police said Tuesday.

The driver who was cited, Ryan Koss, 35, of Dorset, was processed Tuesday evening and released ahead of a September arraignment, state police said. A court official couldn’t say whether Koss had a lawyer, and Koss didn’t immediately return an email message seeking comment.

Williams, 71, of Manchester Center, was pronounced dead at Albany Medical Center in New York.

Richard Treat Williams’ nearly 50-year career included starring roles in the TV series “Everwood” and the movie “Hair.” He appeared in more than 120 TV and film roles, including the movies “The Eagle Has Landed,” “Prince of the City” and “Once Upon a Time in America.”
