Inmates Corey Branch, Tavares Lajuane Graham, Lamonte Rashawn Willis and Kareem Allen Shaw were reported as missing from the Federal Correctional Complex Petersburg's satellite camp at approximately 1:45 a.m. Saturday, the agency said.

The US Marshals Service, FBI and other law enforcement agencies are assisting in the search for the four men, according to the BOP.

Branch, 41, was serving a 160-month sentence for possession with intent to distribute fentanyl and felon in possession of a firearm. Graham, 44, was serving a 120-month sentence for possession with intent to distribute 500 grams or more of cocaine and 28 grams or more of cocaine base, and possession of a firearm in furtherance of a drug trafficking crime, the agency said.

Willis, 30, was serving a 216-month sentence for possessing and concealing a stolen firearm and possession of a firearm by a convicted felon. Shaw, 46, was serving a 194-month sentence for conspiracy to possess with intent to distribute a measurable quantity of heroin, the BOP said in the news release.

Federal Correctional Complex Petersburg's satellite camp is listed as a minimum-security facility, which currently houses 185 male inmates, according to the BOP.

"Hebner and his brother Earl helped author one of the most memorable moments in WWE history when Andre The Giant and Hogan met on WWE Main Event for the WWE Title in 1988. With Dave locked in a closet, Earl and ‘Million Dollar Man’ Ted DiBiase laid a trap for The Hulkster. As Dave joined Earl in the ring, he had the befuddled Hogan seeing double in disbelief," the company said.

The minimum-security facility houses 185 male offenders, officials said. Officials did not release details about how the inmates escaped.

The U.S. Marshals Service, the FBI and other law enforcement agencies were notified, and an internal investigation was initiated, officials said.

The United States Marshals Service, Federal Bureau of Investigation and other law enforcement agencies have been notified of the prisoners’ escape and are taking part in the search. Anyone with information about these individuals is encouraged to contact the United States Marshals Service at 804-545-8501.
