Police say four people have died and over a dozen are injured after a speeding stolen car struck a trailer attached to a bus in San Antonio. Police say two people on the bus were pronounced dead at the scene of the Intestate 35 crash on Thursday, and two others died at a hospital. Another 16 people received treatment for their injuries. The bus driver lost control after the initial collision, then a tractor-trailer smashed into the bus, causing it to crash onto its side. Police say several people fled the stolen car without stopping to help, and that at least one of them was armed.
