Two suspects have been charged with murder, two remain at large as St. Louis police investigate further a series of violent crimes that they say were done just for the thrill of it. 18-year-old Antonio Howard and 19-year-old Dedrick Hampton have been charged with killing Louis Bishop as he walked with his wife Sunday near their St. Louis home. As police looked for the other two suspects, a pair of young men stole a car at gunpoint in downtown St. Louis during rush hour. The four are suspected in two shootings, several carjackings, an assault and a robbery. Police say the suspect seemed to be amused by the violent crimes. It was entertainment for them.
