Kerry Benald Glenn, 30, of Perry, Georgia, was found dead on January 14, 2014, outside a residence on Highway 224 in Houston County from a single gunshot to the head. Investigators say Glenn was not the intended target and ‘‘just happened to be at that house and as a result ended up with a bullet in the back of his head.

Authorities arrested Jamarcus Akeem Clark, 23, of Ashburn, and Devasko Dewayne Lewis, 35, of Cordele, and charged both with murder. Police allege Lewis hired Clark to harm or intimidate Glenn’s uncle, Corey Daniels, a co-defendant in a federal trucking case who had reportedly agreed to testify against Lewis. Five days before Glenn’s killing, shots were fired into Daniels’s mother’s home; investigators believe Clark was responsible for that incident. Phone records and gas-station surveillance are reported to show Lewis and Clark exchanging vehicles, and Clark reportedly admitted to being paid $1,000 and given a gun by Lewis. The murder weapon has not been recovered; both men were held in jail and Lewis was denied bond.

Who in the area might have seen the vehicle exchange or noticed suspicious activity around the Highway 224 residence in the days before January 14, 2014?
