SAN BRUNO (CBS SF) — A man with autism who left an adult care home in San Bruno early Monday morning was killed when he was hit by a car while lying in the road, according to police.

Police are still trying to find the driver who struck 27-year-old Scott Glasner as he was lying on Skyline Boulevard between College Drive and Sneath Lane at about 1:40 a.m. It’s possible the driver doesn’t know they hit a person, police said.

Glasner had left the care home on Fleetwood Drive wearing a dark blue robe shortly after 1:36 a.m. A staff member called police and reported Glasner missing.

At the same time, police received reports of a man running in traffic lanes on Skyline Boulevard not far from the care home.

As police made their way to the area, a driver called police and said a man was lying in the roadway. The caller had swerved to avoid hitting Glasner, but told police that another car was unable to avoid him.

Police found Glasner there suffering from serious injuries and he was pronounced dead at the scene.

The driver of the car that hit him left the area. The witness described the car to police as a dark sedan or crossover.

Police have found no evidence to suggest that Glasner had already been hit at the time and investigators believe he was lying in the road on his own. Police used damaged auto parts to determine the car that hit him was a 2015 or 2016 Mercedes GLA.

Since Glasner was already on the road, damage to the car was minimal, but the front wheel well is likely damaged, police said.

“At this point in the investigation, it is entirely possible that the driver who hit Mr. Glasner was not aware that they had struck a person, and that this is nothing more than a terrible accident,” police said in a statement. “If that is the case, it is our hope that the driver will do the right thing and come forward.”
