Car thieves in Philadelphia drove into a crowd of people this afternoon, killing three pedestrians and seriously injuring three others. One of the dead, the Philadelphia Inquirer reports, was a 10-year-old boy.

According to the Los Angeles Times, two victims died on the scene and the third died later at St. Christopher's Hospital for Children. At least two of the injured are reportedly being treated at Temple Hospital. One is in good condition, the other critical.

The suspects, who stole a white Toyota 4Runner in North Philadelphia and crashed it at Germantown and Allegheny avenues at around 11 am today, escaped on foot and remain at large. Police are offering $40,000 for tips leading to their arrest, the Los Angeles Times reports.

A resident who attempted to resuscitate victims described the scene to the Inquirer:

"I ran across the street, and the boys were laying lifeless," said Karen Payne, who runs a summer camp at the nonprofit. She checked their pulses, she said - one boy had none; the other's was barely there.

"There were bodies all over the lot. . .," she said. "I'm certified in First Aid and CPR - my first instinct was to go to them," she said. "But I couldn't help."
