Posted on FlashAlert: November 7th, 2017 2:23 PM
November 7, 2017 -- On Monday, November 6, 2017, at 5:36 p.m., officers with the Portland Police Bureau's Central Precinct responded to the area near the 4100 block of Southwest Fairview Boulevard regarding a welfare check.
Based on a community member's tip of hearing voices in the wooded area, officers responded to the area of the Hemlock Trail and Southwest Fairview Boulevard to perform a welfare check and search.
As officers prepared to search for the source of the voices, they were aware of a 1998 Ford F-250 associated with 23-year-old Zachary Peterson and 15-year-old Annieka Vaughan that had been located in the area earlier that day.
Officers arrived and requested that a police K-9 team and the Portland Police Bureau Tactical Operation Division's Air Support Unit (ASU) assist with the search.
Officers used FLIR thermal imaging technology, a police K-9 team, and the Air Support Unit to search the area near the Hemlock Trail. The area is densely wooded, steep, and has several ravines. The topography of the area made it difficult to search.
Officers did not locate anyone in the area they searched. At this time it is unknown if this community member's report is associated with Mr. Peterson and Annieka.
Anyone who sees Mr. Peterson or Annieka is asked to call 9-1-1. Community members with non-emergent information should contact the Washington County Sheriff's Office non-emergency line at (503) 629-0111.

Detectives Asking For Public's Help Locating Missing 15-Year-Old
November 2, 2017 -- Washington County Sheriff's Office detectives are asking for the public's assistance locating 15-year-old Annieka Vaughan, who ran away from her residence in Aloha on October 30, 2017.
Detectives believe Annieka is likely with 23-year-old Zachary Petersen of Pasco, WA, who is the suspect in a sexual abuse investigation being conducted by the Benton County Sheriff's Office. Annieka is the alleged victim in that case.
Mr. Petersen also went missing on October 30, which was reported to the Pasco Police Department. Prior to disappearing, Mr. Petersen called the crisis line in Washington. He is believed to be suicidal and possibly in possession of a firearm.
Annieka is described as 5'9" tall, 150 pounds, with brown shoulder length hair and brown eyes. Mr. Petersen is described as 5'10" tall, 150 pounds, with buzzed brown hair and brown eyes.
Mr. Petersen is known to drive a white 1998 Ford F-250 extended cab truck bearing the Washington license plate C20874C. His last known location was in the Portland area, but detectives believe he is possibly traveling to Seaside, OR or Sacramento, CA.
Anyone with information on the whereabouts of Mr. Petersen or Annieka is asked to call non-emergency dispatch at (503) 629-0111.
