Alphonso L. Boyd, 28, known as Izzo to family and friends, was fatally shot on May 27, 2014, on the 1100 block of Conrad Street in Wilmington’s West Side after an argument with a neighbor, Demonte Johnson, also known as Illy. Witnesses said the confrontation escalated and Johnson produced a .32-caliber semiautomatic handgun; Boyd was struck in the back, the bullet penetrating his chest. Officers arrived about 9:30 p.m.; Officer Douglas Rivell began CPR but Boyd was pronounced dead that evening. An autopsy listed the gunshot wound as the cause of death.

Detective Thomas Curley led the homicide probe. Multiple witnesses identified Johnson in a photographic lineup and at trial, and investigators developed cellphone records and other evidence linking him to the scene. Johnson was interviewed on June 1, 2014, and later indicted by a New Castle County grand jury on August 31, 2015; a formal arrest is recorded as September 9, 2015. After a mistrial in March 2017, testimony from eyewitnesses, cellphone location analysis, and recorded jail calls were presented at a second trial.

Anyone who knew Alphonso Boyd, where he lived, or who witnessed the May 27, 2014 shooting is asked to come forward with information.
