A convicted Indiana killer faces ghastly, new murder charges after allegedly killing -- then eating -- the girlfriend who'd posted his bond on earlier charges.

A probable cause statement released Monday and obtained by WAVE3 says Joseph Oberhansley allegedly stabbed his girlfriend Tammy Jo Blanton to death before eating portions of her brain, lungs, and heart.

Blanton called Jeffersonville police at 3 a.m. on Sept. 11th saying Oberhansley, 33, was trying to get inside her home. Police sent him away, but they returned at 10 a.m. to check on Blanton at the urging of her coworkers.

When officers arrived, they found Blanton's bloodied body in a bathtub with sections of her skull cut out. According to the report: "[Oberhansley] further admitted to cooking a section of her brain and eating it."

Oberhansley has a long criminal history going back to at least 2000 when he was convicted of manslaughter and attempted murder for killing his then-girlfriend Sabrina Elder, 17, and critically wounding his mother, the Desert News reported at the time.

Just days before the killing, Elder had given birth to Oberhansley's child.

He was released on parole in 2012, but in 2013 he was in trouble for allegedly choking out another patron in a bar and resisting arrest. He was naked during the attack.

Two months ago, Oberhansley was arrested following erratic driving that sparked a slow-speed police chase. Blanton paid a $1,000 bond to secure his release.

"I'm his fiancée," Blanton said in court on July 23 before posting the bond.

Clark County Prosecutor Jeremy Mull said he had attempted to raise the bond when he discovered Oberhansley faced charges for allegedly attacking the customer in the bar last year. Despite his pleas for a higher bond, Mull told WAVE3 that another prosecutor lowered the bond, allowing Oberhansley to walk free. That prosecutor has now resigned.

"I felt he was dangerous, I was right, he was," Mull told the station. "And he was released without my knowledge. That devastates me."
