An ex-convict who told cops he fatally stabbed his ex-girlfriend, then cooked and ate some of her organs, may now also be charged with raping her. Joseph Oberhansley, from Jeffersonville, Indiana, is charged with murder and abuse of a corpse in the death of 46-year-old Tammy Jo Harbin Blanton last September. On Tuesday, Clark County Prosecutor Jeremy Mull asked for rape to be added to those charges and a judge will consider the request on May 4, the Courier-Journal of Louisville reported. The motion to change the charges comes after lab results for the victim's body were returned. 'Cannibal killer': Joseph Oberhansley, who admitted to killing his ex-girlfriend before eating some of her organs last year, could now face a rape charge. Prosecutors say they will recommend the death penalty . Murdered: Tammy Jo Blanton, right, had called police asking for help just hours before she was found dead . Last year, prosecutors said they intended to seek the death penalty in the case. Juries in Indiana cannot recommend a death sentence or life without parole unless they agree there is at least one aggravating circumstance beyond a reasonable doubt, the law says. Rape, burglary and dismemberment are among those aggravated circumstances. Oberhansley, now 34, was convicted of manslaughter in the 1998 shooting death of his then-girlfriend, 17-year-old Sabrina Elder, in Salt Lake City just days after the birth of their son. He served 14 years behind bars for the crime and was discharged from parole on July 23 last year.

On July 31, Tammy Jo Blanton posted his $500 bond for charges of criminal recklessness and resisting law enforcement stemming from a car chase. Then on September 11, she called 911 at around 3am to report that her jilted boyfriend was outside her home and would not leave, according to the probable cause affidavit. Officers arrived on the scene and ordered Oberhansley to leave after Blanton spoke to him outside. At around 10am that morning, police got another call, this time from Blanton's co-worker, asking them to perform a welfare check after she failed to show up for work. Police found that the back door had been forced open and inside, officers discovered Blanton dead under a tarpaulin in the blood-spattered bathroom of her home, with fatal injuries to her head, neck and torso. 'The front of the victim's skull appeared to have been crushed and brain tissue appeared scattered around the bathtub,' the affidavit stated. The statement added that they found a plate covered in blood and bone, as well as bloodied cooking utensils, the Louisville Courier-Journal reported. Scene: Oberhansley allegedly broke down Blanton's backdoor at her Jeffersonville home, pictured, and then forced his way into her bathroom, where she was hiding, and repeatedly stabbed her . When questioned by police, Oberhansley confessed to forcing his way into the bathroom, where Blanton had locked herself, and repeatedly stabbing her. Oberhansley told police he then used an electric jigsaw to open Blanton's skull and ate parts of her brain, heart and lungs. The blade was allegedly recovered from the scene after the grisly death. A trial date is expected to be set by the end of April. Sorry we are not currently accepting comments on this article.
