On the evening of September 23, 1983, armed robbers held up the Kilgore, Texas, Kentucky Fried Chicken just before closing. Five people who were in the restaurant — Joey Johnson, 20, David Maxwell, Monty Landers, Mary Tyler, and Opie Hughes — were abducted, taken to a field on County Road 232, and executed with shots to the back of the head.

Early investigation led to the arrest and charging of James Earl Mankins Jr. after a torn fingernail was found on one of the bodies, but DNA later excluded Mankins and he was released after pre-trial proceedings began. In November 2005 cousins Darnell Hartsfield and Romeo Pinkerton, already incarcerated for other crimes, were arrested and charged with the murders. Pinkerton pleaded guilty in 2007 to five lesser counts of murder and received five concurrent life sentences; Hartsfield was convicted at trial in 2008 and given five consecutive life sentences, a conviction the Texas Sixth Court of Appeals upheld in 2010.

DNA from Opie Hughes’ body indicated she had been sexually assaulted, which investigators say suggests a possible third perpetrator remains unidentified. Does anyone have information about the Kilgore case or the people involved that could shed light on that unresolved lead?
