Bomb squads from Garland and Fort Hood were called to Commerce on Monday night to dispose of a live mortar round that was taken in to the B6UP Pawn & Gun store for appraisal.
According to reports, the woman who took the live mortar into the pawn shop did not know it was live.
The Commerce Police Department was notified around 3 p.m. and immediately called the Garland Bomb Squad to assist in identifying if the bomb was live.
Commerce Director of Public Safety Chris Basham told the Herald-Banner that a call was then made to the Army to properly dispose of the ordnance.
Shortly after 10 p.m., Army personnel left the scene to detonate the bomb at a city-owned property on Ross Street near the former Commerce Fire substation.
The mortar was safely detonated shortly after 11 p.m.
