(ABC) -- A bicyclist who struck and killed a 71-year-old pedestrian in San Francisco has been convicted of felony manslaughter, the first conviction of its kind for a cyclist in the U.S.
Chris Bucchere, 37, was biking through a busy intersection when he struck and killed Sutchi Hui, who was crossing the street with his wife in down downtown San Francisco.
According to the district attorney's office, Bucchere had run through at least two stop signs without stopping on his way to the intersection where he crashed.
They also contend the light was already red by the time Bucchere went into the intersection and slammed into a group of people crossing the street, including Hui, said Stephanie Ong Stillman of the district attorney's office.
Bucchere's attorney, Ted Cassman, told the San Francisco Examiner that he believed the light was yellow.
Hui died four days later, in March 2012, Ong Stillman said.
Bucchere pleaded guilty on Tuesday to the vehicular manslaughter charge, a felony conviction that San Francisco prosecutor George Gascon said was the first time in history a bicyclist had been convicted of felony vehicular manslaughter.
