PORTLAND, Ore. (AP) — Hillsboro police are looking for the boyfriend of a woman who was found stabbed to death in an apartment on Friday.

Detectives said Saturday that 24-year-old Eric Christopher Petersen is a person of interest.

Petersen, who also goes by the name Eric Brown, is 5-foot-11 and weighs 145 pounds. He has reddish-brown hair and blue eyes.

Authorities say Petersen is also wanted on an unrelated arrest warrant for probation violation, and is considered armed and dangerous.

Police identified the homicide victim as 24-year-old Aimie Zdrantan.

The stabbing death was the second in as many weeks in Washington County.

Nicole Laube was killed Aug. 19 while working at the Commons at Timber Creek apartments in Cedar Mill. Police have yet to make an arrest in that case.
