Authorities have confirmed the identify of an elderly man whose body was found at the base of a Lake Belton cliff Monday morning.

87-year-old Robert James McClure of Belton's remains were found near 666 Centex Sportsman Road at 9:32 AM Monday. His body was sent to Dallas for an autopsy, and investigators are still working to determine how he died.

McClure's body was first spotted by boaters, but they and other witnesses have not been able to tell authorities how the man ended up in the water.
