WASHINGTON – The underground bunker allegedly used by a convicted robber was discovered Tuesday by law enforcement, officials said.
Authorities said they found the bunker through an investigation of Bradley Steven Robinett who plead guilty in January to federal charges of escape, being a felon in possession of a firearm, and interstate transportation of a stolen vehicle.
The FBI and Bureau of Alcohol, Tobacco, Firearms, and Explosives developed information during the investigation that suggested Robinett had buried a cache of materials related to his crimes near Lake Sammamish in Sammamish, Washington.
Together with the ATF, Sammamish Police Department, King County Sheriff’s Office, and Washington State Patrol, the FBI’s Evidence Response Team explored an area of King County wetlands behind a condominium development on Lake Sammamish.
They uncovered the bunker and removed more than a dozen large storage containers for further evidence processing.
