The driver, whose identity was not immediately released, was charged with drunken driving.
Police say the runaway vehicle totalled several of the cars it struck.
The driver fled the truck and hid under a parked car where police later found him. Three late-night shootings Saturday left three victims in critical condition yesterday. He was listed in critical condition at Temple University Hospital. A second shooting took place at Edgewood Street and Haddington Avenue, West Philadelphia, where a 41-year old man was wounded in the shoulder. A third shooting at 42nd and Locust streets left a 27-year old man in critical condition at the Hospital of the University of Pennsylvania after he was hit twice in the chest.
