A Novato man accused of intentionally striking cyclists with his pickup truck in West Marin earlier this month has been charged with four felony hit-and-run charges.

Aaron Michael Paff, 21, is scheduled to be arraigned Thursday in Marin Superior Court. He would face up to five years in prison if convicted of all the charges, said Assistant District Attorney Barry Borden.

The Marin County Bicycle Coalition, in announcing the charges to its members, said the organization is “very disappointed that Paff is only facing hit-and-run charges.”

“We believe Paff’s on-road behavior earlier that day points to intent,” said Jim Elias, the group’s executive director. “Hit-and-run charges suggest his only error was not stopping after plowing his truck into four people.”

Borden declined to comment on the prosecution’s legal analysis.

Paff declined to comment Wednesday when contacted at his residence.

The new complaint is not the only hit-and-run case Paff has pending. In May, he was charged with leaving the scene after damaging property with his pickup truck at the Square Shopping Center on Novato Boulevard.

Novato police also found an open container of alcohol in the truck. He has pleaded not guilty in that case, which is a misdemeanor filing.

The incident in West Marin happened on Oct. 7 on Point Reyes-Petaluma Road just west of Hicks Valley Road. The cyclists were participating in the Jensie Gran Fondo of Marin, a ride that benefits the Marin County Bicycle Coalition.

Four bicyclists were struck from behind by a blue Dodge Ram pickup truck, the California Highway Patrol reported. Witnesses said the truck intentionally swerved to the right to swipe the cyclists, Barclay said.

One cyclist, 48-year-old Spencer Fast of Mill Valley, suffered major injuries and was taken by helicopter to Santa Rosa Memorial Hospital.

Three people with less severe injuries were taken by ambulance to Marin General Hospital. They were Robert Grier, 53, of Danville; Oliver Colvin, 55, of Larkspur; and Joseph Olla, 49, of Danville.

A passing motorcyclist who had captured the collision on a helmet camera provided the footage to police. The CHP then disseminated information about the collision and images of the suspect’s truck.

The CHP received numerous tips that led them to identify Paff as the suspect. Police arrested him at his home that night and took his damaged truck into evidence.

Paff was released from jail pending further review from the Marin County District Attorney’s Office. The prosecution filed charges on Tuesday.
