Douglas County Attorney Don Kleine on Thursday said 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 Friday to be arraigned on the new charge.
Investigators said Martinez-Perez is not a legal resident of the United States, and that his country of origin is not yet clear.
