A Chicago thrift store worker was fatally shot Friday after a gun fell out of a donated sock and discharged into her chest.

Maria Carmen Dominguez, 54, was sorting through donated items inside Unique Thrift Store with a co-worker when a .22-caliber pistol fell out of a sock. The co-worker fumbled for the gun as it fell and accidentally fired a single, fatal round, NBC Chicago reports.

“It’s tragic,” said Dominguez’s husband, Victor Campos. “We don’t know what we are going to do.
