CONCORD, N.H. (AP) – Police in Concord, New Hampshire, are asking the public’s help in finding whoever damaged about 50 gravestones in the city’s Old North Cemetery.

Police say it happened last week, sometime from Sunday, June 15th to early Wednesday, the 17th.

Investigators say the gravetones were pushed over or dislodged from their bases.

The city hasn’t put a dollar amount on the damage yet.

President Franklin Pierce is buried in the cemetery, but his monument was not damaged.
