The red 2007 Volkswagen EOS Coupe was located, and new information indicates that John Blaine Reed and his brother Tony are now in possession of a 2002 Gold Acura 32T. A plate reader hit on this license plate near Calexico, Calif., leading police to believe they may be trying to flee to Mexico.

One of the survivors of the deadly Oso slide two years ago is one of the suspects. John Reed, 53, and his brother Tony Reed, 49, are suspected of murdering neighbors Patrick Shunn and his wife Monique Patenaude.

They are convicted felons and believed to be armed and dangerous, Shari Ireton of the Snohomish County Sheriff’s Office said. 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.

At least 25 sheriff’s deputies and volunteers and one dog are searching a 23-plus square-mile area around the victim’s residence. Units include man trackers from Search and Rescue and SWAT, a SAR swift water team, a SAR human remains detection dog team, the helicopter rescue team in SnoHAWK1, and the SAR operations support unit.  Ground teams will search areas off nearby roads and spur roads, wooded areas and waterways, and HRT will search the area by air.

“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. Detectives later confirmed that the Reed brothers are in possession of a red 2007 Volkswagen EOS Coupes, 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.

After the Oso slide, John Reed participated in the hazard mitigation voluntary buy-out of his property, an effort to reduce risk for future flooding to the property. On March 31, Snohomish County took possession of his property.

The families of the victims released this message:
