Coroner IDs security guard killed in MVH shooting, inmate dead after self-inflicted gunshot wound

DAYTON — An inmate receiving treatment at Miami Valley Hospital shot and killed a security guard before shooting himself near the hospital emergency entrance, according to Dayton police.

The inmate has been identified by the Montgomery County Coroner’s Office as 30-year-old Brian Booth.

The security guard was identified as 78-year-old Darrell Holderman.

Police were initially called to the hospital just around 9:45 a.m. Wednesday on reports of a possible self-inflicted gunshot wound outside of the hospital, according to Montgomery County Regional Dispatch records.

Major Brian Johns, of the Dayton Police Department, said Booth was brought to the hospital for treatment around 1 a.m. Wednesday.

In a press conference Wednesday afternoon, Montgomery County Sheriff Rob Streck said he believed the inmate had gotten sick overnight and was transported in relation to a detox.

“There were symptoms of seizures and some things like that,” Streck said.

Around 9:45 a.m., the inmate, who was not identified, overpowered Holderman, was able to get the guard’s gun and shot him.

Holderman was previously identified as a security guard from Merchants Security, a third-party company contracted by the Montgomery County Sheriff’s Office.

Holderman was hospitalized, but later died from his injuries, according to Dayton Police.

Booth died after a self-inflicted gunshot wound, police said.

He was being held in the Montgomery County Jail on a probation violation in regards to a 2015 burglary.

Booth was booked in the jail Sunday, but had been booked six different times on drug-related offenses, according to the Sheriff’s Office.

Streck called the shooting a “senseless and very disturbing tragedy.”

He stated that not every inmate admitted or transported to hospitals for treatment end up being guarded by private security. Each individual is evaluated by supervisors on classification and past crimes to decide if they should remain with deputies.

Streck said this inmate did not show any signs of issues by jail staff and that nothing in his past would have indicated something like this would have happened.

While the investigation into this incident continues, Streck said ordered all Sheriffs deputies to stay with inmates admitted to the hospital.

Streck said this was the only critical incident between an inmate and security with them at the hospital that he was aware of in his over 20-year career.

A spokesperson for Miami Valley Hospital said the hospital was deemed “safe and secure” just after 11:10 a.m.

Emergency department traffic was rerouted to other area hospitals while the crews responded and conducted their investigation. The hospital returned to normal operations and the emergency department reopened just afternoon.

Correction: A previous version of this story indicated the security guard was also a Montgomery County Sheriff’s Office employee. That was incorrect, the security guard was employed by a service used by the sheriff’s office.
