David Gaines was shot and killed outside his home on Huron Avenue in Dayton, Ohio, on September 16, 2014. He was transported to a hospital and pronounced dead in the early hours of September 17; the Montgomery County Coroner’s Office listed multiple gunshot wounds to the torso as the cause of death.

Police say Gaines had visitors at the house before the shooting and believe those individuals were either involved or have information about what happened. Investigators sealed the scene with crime scene tape and blocked traffic while collecting evidence and interviewing witnesses. The case remains unsolved and Dayton Police continue to request the public’s help.

Anyone with information is asked to contact the Dayton Police Department or submit tips to the Ohio Attorney General’s Office.
