SAN FRANCISCO (BCN) — A 62-year-old woman suffered life-threatening injuries Thursday afternoon in one of two unrelated traffic accidents involving rolled over vehicles Thursday afternoon in San Francisco’s Mission District, according to police.

Officers first responded around 3 p.m. to a report of a crash near Mission and 15th streets, police said.

An SUV at that location had allegedly somehow crashed, striking at least six parked cars, before rolling over, according to police.

The victim was entering her parked car when she was struck by the SUV. The impact of the crash reportedly caused her to be thrown several feet, police said.

She suffered traumatic brain injuries as a result of the crash and was taken to a hospital with life threatening injuries, according to police.

The driver of the SUV, a 51-year-old man whose name has not been released, was arrested on suspicion of driving while under the influence, speeding and using a cellphone, Officer Carlos Manfredi said.

About half an hour later, around 3:30 p.m., an unrelated rollover collision was reported near 13th Street and South Van Ness Avenue. There, a truck collided with another vehicle, causing the truck to roll over, according to police.

The driver of the truck was injured, although information about the extent of his injuries was not available.

Officers are investigating what caused the collision.

“It’s unique to have two rollovers so close together in the same district during rush hour,” Officer Carlos Manfredi said Thursday night of the unrelated accidents.
