2:10 p.m.A 48 year-old man was found dead Friday in an SUV on a residential street in Napa, according to the Napa Police Department.

The case remains under investigation, Napa Police Sgt. Debbie Peecook said Saturday.

The Deer Park resident was found in a SUV on the 2300 block of Lone Oak Avenue, a west Napa street that dead ends at a field near Redwood Creek. There was no sign of trauma.

Police have yet to release the name of the man, who was pronounced dead at the scene. Police said an autopsy will be performed.

A neighbor called 911 at around 5 p.m. Friday, according to police.

Svein Karlsen, who has lived across the street for two decades, said he first noticed the SUV at lunchtime, when he came home for about 10 minutes. The vehicle's lights were flickering and a black vehicle was nearby.

"There's always cars down here. That's why I didn't pay much attention to it," Karlsen said Saturday.

He called police after work at around 5 p.m., when he realized the SUV was still there, with someone in the inclined driver's seat.

The individual was wearing jeans, Karlsen said. He could not see much else because the windows were fogged up. He did not realize it was a man until the man’s body was pulled out of the car, he said.
