The driver of a stolen sport utility vehicle slammed into a motorcyclist in SoMa Sunday, leaving her critically injured as he sped away from the scene of the crime.

It was 9:56 Sunday morning, police say, when the driver of a tan GMC Yukon was spotted traveling at a "high rate of speed" near South Van Ness Avenue and Howard Street.

The driver, according to the San Francisco Police Department, then "crossed into oncoming traffic" and struck a woman as she rode her motorcycle.

According to the SFPD, she was critically injured in the collision. She was transported to San Francisco General Hospital, and remains there today.

The driver, who witnesses say looked to be in his 40s, fled the scene. Officers with the SFPD later recovered the vehicle used in the hit-and-run, and determined that it had been reported as stolen.

As of Monday morning, the driver remains at large. As always, anyone with any information on this case (or any other crimes) is urged to call SFPD's Anonymous Tip Line at 415-575-4444 or to text a tip to Tip411 with SFPD at the beginning of the message.
