19-year-old Sergio Perez is accused of beating and raping 93 year old Louise Sollowin in her south Omaha home on Sunday morning. She died Wednesday at the hospital.
Douglas County Attorney Don Kleine says the cause of death was blunt force trauma. Prosecutors say Perez attacked Sollowin while she slept in her bed.
Perez will go before a judge Friday afternoon on the new charge. He's currently being held without bond.
