The bomb squad responded Friday after an authentic military mortar was donated to Deseret Industries.
An employee at the Welfare Square Deseret Industries, 743 W. 700 South, found the round among items that had been tossed into the trash Friday afternoon, Salt Lake police detective Greg Wilking said.
"It looks like the item was donated to Deseret Industries there, and while things were being processed, it was tossed into a Dumpster," Wilking said.
