BOONVILLE, Ind. (AP): Three southwestern Indiana men are charged with grave robbing after allegedly stealing bones and causing damage at a cemetery.

Nicholas Kinder of Evansville and Boonville residents Damon Busing and Ryan Casey are charged with abuse of a corpse and cemetery mischief. They're accused of causing about $450 in damage after stealing the skull and bones from a crypt and knocking the top off of a tombstone at Boonville's Maple Grove Cemetery in early December.

A Boonville police officer acted on a tip that Busing was involved with the cemetery vandalism.

According to police, the 18-year-old admitted he and his friends visited the grave of Casey's grandmother Dec. 8, but he denied damaging grave sites. Police say Kinder said Busing stole human remains from a casket.

All three men have pleaded not guilty.
