Patrick Shunn, 45, and his wife Monique Patenaude, 46, lived on a rural property near the North Fork Stillaguamish River in Arlington, Washington. A long-running dispute with a neighbor, John Reed, over access via a shared driveway had escalated for years and included threats and arguments; Patenaude had reported that Reed was squatting on land after a county buyout.

On April 11, 2016, prosecutors say Reed ambushed Patenaude as she returned from running errands, shooting her three times, and later shot Patrick Shunn in the back of the head when he returned home. The couple’s vehicles were found pushed down a steep, wooded embankment with large amounts of blood inside. Investigators allege John Reed and his brother Tony fled to Mexico; Tony later admitted helping bury the couple and led police to a remote shallow grave. John Reed was captured and extradited to face charges.

John Reed was convicted of aggravated first-degree murder in Patrick Shunn’s death and of second-degree murder for Patenaude’s death; Tony Reed pleaded guilty to rendering criminal assistance and received a 14-month sentence. If anyone knew Patrick or Monique, or has information about the dispute with the Reed family, please share what was seen or heard.
