St. Louis police say they have two young men in custody and are looking for two others who have terrorized the city for more than three days for the thrill of it. The men – ages 16 to 20 – are suspected in a series of violent crimes, including the shooting death of a St. Louis man Sunday afternoon, a shooting that took place for no apparent reason other than to watch a man die. St. Louis detectives also suspect the two in the shooting and wounding of an Army recruiter who was shot as his family escaped an apparent attempt to carjack their van on I-70. So far, St. Louis police suspect the four in the two shootings, seven carjackings, a robbery and another attempted carjacking. Police believe the four became intoxicated and exhilarated by their crimes.
