ST. LOUIS • Reginald Clemons, who was sentenced to death for the 1991 killings of two sisters at the Old Chain of Rocks Bridge before his conviction was overturned in 2015, pleaded guilty to murder and other charges Monday in exchange for multiple sentences of life in prison.

Clemons, 46, pleaded guilty to five counts in all: two counts of second-degree murder, two counts of rape and one count of first-degree robbery.

Clemons admitted that he and three others met Julie Kerry, 20, and Robin Kerry, 19, and their cousin on the closed bridge late on the night of April 4, 1991.

They robbed the cousin, Thomas Cummins, of cash and a watch, Assistant Attorney General Gregory Goodwin said in court. They then raped the Kerry sisters, forced all three through a manhole and onto the substructure of the bridge and pushed the Kerrys off, he said. They forced Cummins to jump from the bridge at gunpoint, Goodwin said, but Cummins survived.

Julie Kerry’s body was found three weeks later in Pemiscot County. Robin Kerry’s body was never found.

DNA from Clemons and a co-defendant, Marlin Gray, indicative of sexual activity, was found on pants Gray wore during the crime, the plea says.
