An Oklahoma woman slashed the face of her boyfriend’s dead ex-girlfriend while the body was on display at a funeral home, police say.

Shaynna Smith, 28, of Tulsa was charged with illegal dissection of a body. She cut the dead woman’s hair and slashed the face from her hairline to the tip of her nose during a viewing last Friday at Moore Funeral Home, according to Tulsa police.

“The funeral director informed us that the deceased’s body was in a viewing room when some friends and family came to pay their respects,” said Leland Ashley, a spokesman for Tulsa police. “When they entered, they observed at least one female with their hands inside the casket.”

The woman, a 38-year-old whose cause of death was not disclosed, “once dated Smith’s current boyfriend,” Ashley said, but police did not know of a motive for the desecration. The dead woman’s makeup was smeared, and Smith allegedly stole her shoes.

Smith then went to the dead woman’s home “under the pretense that she was sent there to receive jewelry so that she could take it back and put it on the deceased for viewing,” Tulsa police Sgt. Shane Tuell told NBC News affiliate KJRH.

When officers arrived at the home, they found Smith, who had a knife with pieces of hair on it, Ashley said.
