NOVATO (CBS SF) — A sketch of a pedestrian killed in a hit-and-run on U.S. Highway 101 in Novato was released Monday in the hope someone can identify the victim.

The California Highway Patrol also announced Monday it has identified a person of interest in the case. The victim, a white man in his mid-50s was killed along southbound 101 in Novato on Thursday.

“The person has been interviewed and we believe we have the (responsible) individual,” said CHP Officer Andrew Barclay of the person of interest from Hayward. So far, no arrest has been made.

CHP officers said they have located and took into evidence the vehicle involved in the fatal hit-and-run after receiving numerous calls, emails and messages from concerned citizens.

Last week, CHP officials said the vehicle was believed to be a metallic silver 2006 to 2013 Nissan Versa with damage to the right side of the vehicle.

A big-rig driver spotted the victim’s body in the road between the Atherton Avenue on-ramp and the slow lanes of southbound Highway 101 around 1 a.m. Thursday.

The Marin County coroner’s office released a photo-quality digital sketch of the deceased pedestrian and is asking for the public’s help in identifying him.

The pedestrian is a white man in his mid-50s, 5 feet 10 inches tall, 200 pounds with hazel eyes, gray salt and pepper colored hair that is about shoulder length in the back, Chief Deputy Coroner Darrell Harris said.

The man had gray stubble beard growth and thick bushy eyebrows but no scars or tattoos on his body. He was wearing a maroon long-sleeved, extra large Hanes Beefy T-shirt, brown carpenter/painter-style pants, a brown leather belt and black slip-on loafer-style shoes.

Anyone who recognizes the man in the sketch is asked to call the Marin County Sheriff’s Office at (415) 473-6043.
