PORTLAND, Ore. (KOIN) – The suspect wanted for killing a man in a Northeast Portland apartment and for a nearby rape was arrested Friday night in Hillsboro.

Alexander R. Ortiz, 33, was wanted for the murder of Eleazar “Tony” Herrera Villegas. The 59-year-old Villegas and a dog (named Max) were both found dead Monday afternoon at the Terrace at Columbia Knoll Apartments. Officials haven’t revealed how Villegas or Max died.

It didn’t take long for investigators to zero in on Ortiz, who is a registered sex offender. On Monday morning before Villegas’ body was found, police were called to a nearby hotel in response to a sex assault case and Ortiz ran from the hotel when police were called, authorities said.

The hotel is adjacent to Villegas’ apartment complex in the 8300 block of NE Sandy Boulevard.

KOIN 6 News learned an arrest warrant was filed against Ortiz on Thursday, March 3. Police booked him into jail on 3 counts: aggravated murder, rape and a single count of aggravated animal abuse.

Ortiz was arrested Friday night in the 700 block of Southeast Cedar Street by the Washington County Sheriff’s tactical response team. He is being charged with aggravated murder because he allegedly killed Herrera Villegas immediately after committing rape at a nearby hotel and that the death was done in an act to conceal that crime.

Investigators confirmed Ortiz was also wanted in Washington County stemming from a February sexual assault in Hillsboro.

Prosecutors in Washington County have filed for an arrest warrant but it remains sealed. KOIN 6 News learned that bail for the Hillsboro rape case is set at $500,000, but he is being held without bail in Multnomah County.

It is expected Ortiz will be arraigned on Monday.

Anyone with information on the case is asked to call 503.823.4357.
