The 30-year-old driver who struck two 12-year-old boys in San Francisco's Marina District Wednesday morning has been arrested on suspicion of DUI, according to San Francisco police.
Officer Albie Esparza said the driver stayed at the scene after the boys were reported hit just before 8:30 a.m. at Bay and Buchanan streets. They were on their way to Marina Middle School.
The boys were taken to San Francisco General Hospital with serious injuries. They are expected to survive, police said.
A police captain later told NBC Bay Area that the driver of the SUV who struck the boys apparently didn't see the pair because a delivery truck had stopped at the crosswalk to let them pass.
The driver, identified as Kristen Andereck, stayed at the scene to talk with police and was cooperating with the investigation.
What speed she was driving was not immediately clear, police said, but the intersection where the boys were struck has no stop sign or stop light. In general, neighbors complain that people drive too fast in this area.
Some residents said drivers routinely speed up to 40 to 50 mph through a 25 mph zone.
Police originally said the boys were 10 years old.
