Robert B. Vallandingham

Correction Officer Robert Vallandingham was killed when he was strangled by inmates during a prison riot at the Southern Ohio Correctional Facility that involved 450 inmates.

He and several other officers had been taken hostage during the riot and had been held for four days before Officer Vallandingham was murdered and his body thrown into the prison yard. During the 11 day siege nine inmates, alleged snitches, were executed. It was the longest prison riot in U.S. history that eventually settled into one of the longest sieges in U.S. prison history. More than 1000 national guard members were activated and more than 100 state troopers.

Five inmates, 24, 26, 30, 36, and 47 were sentenced to death for Officer Vallandingham's murder. In 2021 four were awaiting their execution dates. The youngest of the five is to be executed on November 16, 2023.

Officer Vallandingham had previously served with the United States Army during the Vietnam War. He was survived by his wife and son and is buried at Greenlawn Cemetery in Portsmouth, Ohio.
