The backpack was discovered at the base of a railroad trestle in the 200 block of South Riverview Drive.
Immediately, a bomb team, F.B.I. agents and members of Alcohol Tobacco and Firearms were brought in.
A SEMO bomb team robot pulled the pack a safe distance from the railroad property and dismantled it with a water cannon. Inside, they found clothing and personal items.
The owner of the package has not been identified.
