William Stamps Sr., 58, was shot and killed on the night of March 27, 2015, in Maywood, Illinois. He was found in his car on the 1400 block of South 19th Avenue, having been shot multiple times, and was pronounced dead shortly after arrival at Loyola University Medical Center. Stamps owned Right Way Auto Sales and was described as a well-known local businessman devoted to his family and business.

Investigators noted a possible connection to recent violence: days earlier, on March 23, 2015, Ferris Howard was killed in a shooting that was believed to have targeted William Stamps Jr., the son of the victim. In 2012 William Stamps Jr. and Ferris Howard had been charged in a murder and injury during a gang-related shootout but were released for insufficient evidence. Authorities say the motive for Stamps Sr.’s killing is unclear and no arrests have been announced; the assailants remain at large.

Does anyone have information about activity on South 19th Avenue that night or knew William Stamps Sr. or his business and might help investigators?
