Devon Eugene Jones, 28, was found in his Summerville, South Carolina home on Barons Road on November 8, 2018, with a fatal gunshot wound to the head. The Dorchester County Sheriff’s Office treated the death as a homicide and opened a full investigation.

On November 16, 2018, authorities announced arrests in the case. A 17-year-old, Christopher Harmon, was taken into custody in Ravenel by the Charleston County Sheriff’s Office, and 25-year-old Brandon Bivens — already jailed in Colleton County on unrelated charges — was also implicated. Arrest warrants allege Harmon and Bivens went to Jones’s residence intending to rob him of a controlled substance and that Jones was shot during that incident. Both were denied bond and held at the Dorchester County Detention Center.

Investigators also identified a third person of interest, 27-year-old John Carroll O’Quinn, for whom a murder warrant was issued; he was described as armed and dangerous. Does anyone have information about Jones, the people named, or sightings of John Carroll O’Quinn around November 2018?
