JEFFERSONVILLE, Ind. (AP) – A prosecutor is seeking to file additional charges against a southern Indiana man who confessed to fatally stabbing his ex-girlfriend and mutilating her body.

The Indianapolis Star (http://indy.st/1EaPRFD ) reports the judge has ordered a May 4 hearing about prosecutor Jeremy Mull's request to amend charges to include rape among those that 34-year-old Joseph Oberhansley faces.

Mull wants to add the rape charges as aggravated circumstances for jurors to consider in a capital punishment phase if they convict Oberhansley of murdering 46-year-old Tammy Jo Blanton. Rape, burglary and dismemberment are among the aggravated circumstances required for jurors to consider the death penalty.

Court documents say Oberhansley confessed to Jeffersonville police that he broke into Blanton's home Sept. 11, killed her with a knife and ate some of her organs.
