An hour-plus delay early Thursday night at I-280 northbound at Geneva Avenue was caused by a fatal accident where the suspect was attempting to evade police.

It was a rough July 4th on Interstate 280 this year. An early afternoon fire in San Jose, likely caused by fireworks, slowed traffic and caused some damage. Here in San Francisco, an I-280 pedestrian fatality also brought northbound traffic to a near halt for a few hours. Around 5 p.m. police responded to an assault call at the Muni and BART Balboa Park station. When police arrived, the suspect ran to a freeway median and into the northbound lanes of 280 at Geneva Avenue, where the suspect was hit by a car and killed according to the Chronicle.

KPIX has some video via the Citizen App from the scene, where California Highway Patrol had shut down three northbound lanes of 280 for more than an hour Thursday evening.

“This is not a hit and run,” CHP officer Pedro Santiago told the Chronicle. “The vehicle stopped and the driver is cooperating.”

Because this incident occurred on both a highway and at a Muni station, law enforcement agencies are conducting separate investigations; CHP is handling the traffic fatality, while SFPD is handling the assault.

Neither agency has identified the now-deceased suspect. SFPD says the assault victim, also unidentified, received medical care on the scene for non-life-threatening injuries, but was not hospitalized.
