An Indiana man accused of fatally stabbing his ex-girlfriend told police that he mutilated her body and ate several of her organs, according to court records.

Joseph A. Oberhansley, 33, who appeared in Clark Circuit Court on Monday, is accused of killing Tammy Jo Blanton, 46. He is charged with murder, abuse of a corpse and breaking and entering in the case.

“After you’ve been prosecuting for so long, you think you’ve seen everything,” Prosecutor Steve Stewart said. “… I’ve never seen this.”

Oberhansley — who has a previous conviction for manslaughter in Utah — was arrested last Thursday after police came to Blanton’s house looking for her because she hadn’t shown up for work.

Police said he acted suspiciously when officers asked him about Blanton’s whereabouts after knocking on the door about 10 a.m.

There was a fresh cut across his knuckles, according to a police affidavit made public Monday in court.

Based on their observations, the affidavit said, the officers searched Oberhansley for weapons and found a folding blade tucked in his back pocket, covered with what appeared to be blood and hair.

An officer then walked through the house calling Blanton’s name before finding her bloody body under a vinyl camping tent draped over the bathtub, the affidavit said. Her skull had apparently been crushed, the affidavit said.

An autopsy Friday revealed Blanton died of multiple sharp force trauma to the head, neck and torso, and that parts of her heart, lungs and brain were missing.

Police also found a “plate with what appeared to be skull bone and blood” on it, the affidavit said, as well as a skillet and pair of tongs with blood on the handles.

Police said Oberhansley told officers he removed several of Blanton’s organs and ate them, both cooked and raw. Tissue was found in a garbage can, the affidavit said.

When he appeared in shackles Monday before Judge Vicki Carmichael, Oberhansley said he could not have committed the crimes.

While Joseph Oberhansley is accused of the gruesome acts, he said, “that’s not my name. Obviously you’ve got the wrong guy.”

Instead, he said, his name was actually “Zeus Brown.” And he said he did not know how old he is and whether he is a U.S. citizen.

Carmichael said a public defender would be assigned to him.

Meanwhile, Jeremy Mull, a chief deputy prosecutor, said he was “not buying” the defendant’s story. “There’s a motive and a reason” for Oberhansley’s denials, he said.

“There’s no doubt in my mind that he is responsible for” Blanton’s murder, Mull said.
