Darrell Holderman, a 78-year-old Marine veteran from Warren County, was shot and killed on June 1, 2022, while working as a security guard at Miami Valley Hospital in Dayton, Ohio.

Holderman’s family remembered him as a devoted father and grandfather who had devoted his life to helping others and serving his country; they said he was not supposed to be at the hospital that day. Reports note Booth had prior arrests for burglary, theft and possession of drug instruments and was in custody on a parole violation from a 2015 burglary charge, but he was not classified as a high-risk transfer. How Booth managed to overpower Holderman and obtain the gun remains unclear.

Does anyone have information about security procedures at Miami Valley Hospital that day or witnessed the incident?
