Another explosion in Austin, Texas, injured one person Tuesday night, but police confirmed that the explosion was unrelated to the previous package bombs that have killed two people and injured several others this month.
The explosion occurred after a "military-type memento" was dropped off at a Goodwill store on Austin's south side, Assistant Police Chief Ely Reyes said. He further described it as a 40mm artillery simulator.
Reyes said the simulator "initiated" at about 7 p.m. after being handled by a Goodwill employee.
