arrest made in sf hit and run

the driver who hit andrew bennett and his four year old son robby has turned herself in. streetsblog, which has been covering this story from the beginning (i'm pretty sure it still hasn't turned up in the chronicle), has the update.

the short version: she's 16, and she's facing felony hit-and-run charges. robby bennett is still processing what happened, although his only physical injuries were abrasions. andrew bennett is seeing lots of doctors to try to heal from his broken back.
