JEFFERSON, Indiana (WAVE) — Grisly court documents allege that an Indiana man stabbed his girlfriend to death then ate part of her brain, heart and lungs, WAVE reports.

Joseph Oberhansley faces felony murder charges in the brutal Sept. 11 death of Tammy Jo Blanton.

That day, Jeffersonville police officers were called to the victim’s home on Locust Street just before 3 a.m., according to a probable cause affidavit.

Blanton told officers that her ex-boyfriend, Oberhansley, was outside and refusing to leave after she changed the locks, investigators said. Officers said they watched the suspect drive away before they left.

“I believe the officers that responded to that call responded appropriately and took all measures that were necessary to ensure the peace at that time,” said Detective Lt. Todd Hollis, with the Jeffersonville Police Department.

But just hours later, police were back at Blanton’s home after a co-worker called them over. When officers went to check on Blanton, Oberhansley answered the door.

According to court documents, officers took down Oberhensley when he started to reach in his pocket. In the bathroom, police said they found Blanton’s body in the tub, covered by a vinyl tarp

“After being a prosecutor for so long, you’ve think you’ve seen everything and this is one of those cases where I’ve never seen this,” said Steven Stewart, Clark County Prosecutor.

After Oberhansley was taken into custody, police said he confessed to killing Blanton with a knife.

The affidavit alleges that he also admitted to dismembering Blanton and eating parts of her body, including her brain. Court records state that Blanton’s heart was removed along with her skull and part of her lungs.

“Particularly in a case like this where there is such extraordinary allegations of cannibalism, it’s got to make people in our community scratch their heads and say, ‘What’s going on here?’ and it does the same thing to me,” Stewart said.

Prosecutors said Oberhansley was free on parole for the murder of his girlfriend when he was a teenager. Last year, he was charged with strangulation and resisting law enforcement after an incident at a bar.

At a court appearance Monday, Oberhansley declared for himself a new identity.

“My name is Zeus Brown. I am no longer Mr. Oberhensley. I am Zeus Brown. Me,” he said.

But a prosecutor isn’t believing that.

“I don’t buy it. I think there is a motive and a reason for what you saw in the courtroom today and I don’t believe that he really believes that he is Zeus Brown,” said Jeremy Mull, Clark County Chief Deputy Prosecutor.
