John Blaine Reed, 53, and his brother Tony Clyde Reed, 49, are suspected of murdering Patrick Shunn and his wife Monique Patenaude.

Detectives are asking for the public’s help in locating the suspects, who are convicted felons and believed to be armed and dangerous, a sheriff’s news release says. Detectives were able to obtain video surveillance footage tying the Reed brothers to the disposal of Shunn’s and Patenaude’s vehicles.

Detectives believe the couple were victims of homicidal violence based on evidence collected at the scene of the missing couple’s vehicles, as well as the former residence of John Reed.

Sheriff’s Office search and rescue teams continue to search for Shunn and Patenaude in a large area north of the homes of the victims near Oso.

“The recovery of Patrick and Monique is our agency’s number one priority right now, for the sake of their families,” Sheriff Ty Trenary said.  “Our second priority is getting the Reed brothers into custody and off the streets.”

Investigators located a vehicle belonging to John Reed in Ellensburg.  It is believed the brothers were recently in that area, but their current location is unknown now.

Detectives have confirmed that the Reed brothers are in possession of a red 2007 Volkswagen EOS Coupes, Washington plates AXH5106, a vehicle that belongs to their parents.

John Reed is 5-foot-8, 190 pounds with hazel eyes and gray hair.  Tony Reed is 5-foot-11, 150 pounds with green eyes and gray hair.

The Landrover and Jeep belonging to the couple were located April 14 in a remote, wooded area near Oso. The vehicles were approximately 200 feet from each other and had extensive damage.

The Arlington couple were reported missing by neighbors April 12.  Shunn, 45, was last seen at his workplace in Kirkland April 11, but did not report for work the next day. Patenaude, 46, was last seen around 1 p.m. that same day near the couple’s residence in the 27800 block of Whitman Road.

Word of the missing couple leaked out early on social media. Friends said they were concerned because of an ongoing battle between the couple and a neighbor.

The families of the victims released this message:

“We appreciate the effort that the community and specifically law enforcement has put forth to locate Patrick and Monique. Patrick and Monique are a loving couple who are loved by friends and family. Their 20-acre farm and animals are their passion. They love the outdoors, love their family and friends and, most of all, love life. Wherever they are, they are together.

“We appreciate efforts to organize search parties to look for Patrick and Monique. However, we’d like to ask the public to please let law enforcement authorities continue the search and the investigation. If help from the public is needed, they will let you know.”
