Two men have been arrested after two teenage best friends were killed when their car was struck by allegedly speeding muscle cars in Victorville, California. Prosecutors say one driver, Terry Lamar Easter, was racing at up to 117mph, placing his eight-year-old son at risk and then fleeing the scene, making the case a stark example of the potentially fatal consequences of street racing.

Maddalyn Dailey, 17, and Isabell Hill, 16, died at the scene on 14 August after Dailey’s Acura was hit at an intersection and split in half. Easter, 50, faces two murder charges, a racing charge and a child-abuse charge; George Gary Sanchez, 49, who allegedly drove the second car, has not yet been charged. Three other people were arrested on suspicion of helping Easter after the crash, but were later released after cooperating with investigators.
