19 year old Sergio Perez appeared in a Douglas County courtroom Friday afternoon.
According to Channel 6 reporter Brian Mastre, Sergio Martinez-Perez spoke through an interpreter, but said very little in his brief court appearance Friday afternoon.
Prosecutors said Perez had told them that on the night of the attack he was angry with women and was going to have sex with someone.
Douglas County Attorney Don Kleine charged Perez with first-degree murder in the death of Louise Sollowin.
Police say the 19-year-old Martinez-Perez is in the country illegally and has been in Omaha less than two months. There is an immigration hold on him.
Prosecutors agreed to drop the initial charges of first-degree sexual assault, assault and burglary. The preliminary hearing for Perez will be August 12 at 9:00 a.m.
