The box contained at least three loose US Mk 2 fragmentation grenades, dating back to the 1940s. The resident, who had purchased the container expecting old books or antique decor, immediately contacted authorities upon opening it. The Austin Police Department quickly secured the scene in northwest Austin, establishing a perimeter to keep neighbors safe while waiting for Explosive Ordnance Disposal (EOD) technicians.
Technicians used X-rays to inspect the metal casings, confirming the devices were "active and live." While the grenades were stable enough not to detonate while sitting in the box, they posed a significant risk if handled incorrectly. An Austin Police Department spokesperson told Chron that the bomb squad assessed the devices based on their X-ray interpretation and treated them as live ordnance.
The department praised its bomb squad officers on Instagram, noting the dangerous and precise nature of handling 80-year-old explosives with unknown stability. "These officers bring a level of training, expertise, and steady nerves that most people never see," the APD wrote. Police later confirmed the incident was entirely accidental and not part of any criminal investigation, ensuring the buyer faced no legal trouble.
The EOD team safely secured and removed the six grenades from the home. The incident concluded with no injuries and no criminal charges filed against the resident, highlighting the unpredictable risks of estate sales in areas with historical military connections.
