A 19-year-old Hispanic accused of beating and raping an elderly woman who later died will now face a murder charge

Prosecutors said that Sergio Martinez-Perez beat and sexually assaulted 93-year-old Louise Sollowin in her home. Sollowin later died. Douglas County Attorney Don Kleine said that Martinez-Perez will be charged with first-degree murder. Autopsy results showed that Sollowin's cause of death was blunt force trauma. Martinez-Perez, who already faces charges of first-degree sexual assault, first-degree assault and burglary, is set to appear before a judge to be arraigned on the new charge. Prosecutors said that Martinez-Perez admitted to the assault and rape, saying that he was mad at women after a night of drinking. Investigators said that Martinez-Perez is not a legal resident of the United States, and that his country of origin is not yet clear. The victim’s family said that a detective told them that Perez has been in the country for about four months.
