A driver in a rented Tesla ran a red light and rammed into a couple celebrating their wedding anniversary in San Francisco, killing the husband and critically injuring the wife.

Officials are investigating whether the Tesla, which was rented via the service Get Around, was on “Autopilot,” a partially self-driving system at the time of Sunday’s crash.

Video obtained by KGO-TV Tuesday shows the speeding Tesla broadsiding a Mini Cooper, which had the green light, and crashing into the Clovis, Calif., couple, who were at a crosswalk.

The wife, Kelly Dean, can be seen throwing her arm across her husband, Benjamin Dean, in an attempt to push him back, moments before the collision — which sent them flying into the air.

“She was incoherent, gurgling noises, she was on her stomach with her head off to one side,” said Bob Navarro, who ran to help the couple and stayed with an unresponsive Kelly. “I could see a lot of blood coming from her head and we just kept talking to her, talking to her.”

As of Monday night, Kelly was at San Francisco General Hospital in critical condition, according to the outlet. But her husband of three years, 39-year-old Benjamin, died.

The 22-year-old driver of the rented Tesla, who wasn’t publicly identified, was arrested on suspicion of vehicular manslaughter and running a red light, police said Monday.

Drugs and alcohol didn’t appear to be a factor. The woman was going at least 45 mph in a 25 to 30 mph zone, when she ran the red light, police said.
