Authorities say a 93-year-old Omaha woman has died after being beaten and raped.

Omaha police say she died Wednesday, three days after the attack in her home. According to a police report, an officer who was sent to check on the woman found her covered in blood in a bedroom around 9 a.m. Sunday. The officer reported that Sergio Perez was naked and passed out on top of the woman.

Perez remained in jail on Thursday, as prosecutors consider a murder charge.  Prosecutors say Perez admitted to the assault and rape, saying he was mad at women after a night of drinking.

Perez had been working as a roofer and has no known ties to Omaha.
