Though a San Francisco woman was in a clearly marked crosswalk at a four-way stop, she was still somehow struck and killed by an errant driver Monday afternoon.

61-year-old Rose Kelly was walking east in the crosswalk at 33rd Avenue and Cabrillo Street at 1:21 p.m. Monday, San Francisco Police Department spokesperson Officer Albie Esparza says, when a 62-year-old man driving a GMC truck north on 33rd hit Kelly as she crossed.

Kelly suffered injuries to her head and chest, and was transported to San Francisco General Hospital, where she was pronounced dead, Esparza says.

Streetsblog reports that the SFPD filed misdemeanor vehicular manslaughter charges against the truck driver, but that "It’s now up to District Attorney George Gascón to follow through with the prosecution."

According to a SF Chronicle report from Friday, seven pedestrians have been killed by drivers of vehicles in 2015. Kelly's death will bring that number up to eight. This time last year, nine pedestrians had been killed by drivers on San Francisco's streets.
