Three people were killed and six others were injured after a car went onto a sidewalk under the San Diego City College bridge around 9 a.m. this morning.
The driver identified himself to police and is currently being detained for driving while impaired.
Law enforcement says there were a number of homeless people in the area.
San Diego Police Chief David Nisleit says "We had folks who had some of the belongings on the sidewalk if you would. If you are familiar with 1500 B it is completely covered and on the north side of the street there is a pretty wide sidewalk and there were several tents up and people had their belongings there. Obviously, with the weather last night, it was cold and wet, and now obviously, raining now and people were trying to get out the weather."
Two of the six people taken to the hospital are in critical condition.
