The Richland bomb squad destroyed a suspicious metal briefcase on Saturday evening near American Rock Quarry. The suspicious case was reportedly left on Kennedy Road near a vineyard west of the quarry according to news reports of the Benton County Sheriffs Office. Police assessed it was safer to just blow up the case but did not find anything of interest inside after the explosion.

The case was suspicious because it was left upright like it was set down carefully, not thrown or dropped from a moving car.
