Thieves stole an unknown amount of plutonium and radioactive monitoring equipment from the backseat of an SUV parked overnight at a Marriott hotel in San Antonio, Texas, last year. No one knows where it is and the government is not talking. In March 2017, two lab security experts from the Department of Energy’s Idaho National Laboratory were tasked with transporting plutonium from a non-profit research lab in San Antonio, Texas, according to a report from the Center for Public Integrity. Before returning to Idaho the pair stopped at a Marriott Hotel off of Interstate 410 and left the radioactive material in the backseat of a rented Ford Expedition in a “high-crime neighborhood filled with temp agencies and ranch homes,” the Center for Public Integrity report said. When they returned the next morning the rear car windows had been smashed and unknown amounts cesium and plutonium, materials that could potentially be used to fuel the creation of nuclear weapons, were gone. More than a year later, the plutonium and cesium have not been recovered and police have no idea where the materials went.
