PERU, Ind. (AP) — State conservation officers are investigating vandalism that damaged a northern Indiana memorial to honors soldiers killed in the War of 1812.

The state Department of Natural Resources’ law enforcement division says nine tombstones, a memorial marker and a flag pole were damaged at the 1812 Soldiers Memorial at Mississinewa Reservoir in Peru.
