Mike Barksdale and Dontrell had been friends for 11 years before Williams was gunned down early Monday morning in a convenience store robbery.
Williams lived with Barksdale in a north Columbus home.
He said the killing at the Circle K at the intersection of Forrest and Floyd Roads was senseless.
“Dontrell was completely compliant,” Barksdale said. “It would be a different story if he stood there and was trying to argue or fight back with the man.”
