Richard Singley, 53, was killed the evening of December 15, 2017, in west Mobile, Alabama, after a 911 caller reported a single gunshot. Officers who responded to the 1400 block of Repoll Road at about 6:43 p.m. found him outside in his front yard, already wounded by an apparent gunshot; he was pronounced dead at the scene.

Investigators determined the shooting occurred during an altercation, described publicly as a confrontation that escalated into fatal gunfire. Authorities said the case would be presented to a grand jury, but public updates did not identify a named suspect, describe a manhunt, or announce an arrest.

Does anyone who lived in or near the 1400 block of Repoll Road that night have information about the altercation or anyone seen leaving the scene?
