EVERETT, Wash. (AP) — A sheriff in Washington state says two guns used to murder a couple last year may have been dumped in western Arizona or eastern California near the U.S.-Mexico border, and authorities are asking people to come forward if they found the weapons.

The Snohomish County Sheriff's Office north of Seattle says investigators believe the 9 mm semi-automatic pistol and .357 revolver may have been ditched in Arizona along the Tucson-Ajo Highway or State Route 95 from Yuma, or in California, along State Route 111 or State Route 78 near Calexico.

Authorities say John Reed executed his neighbors, Patrick Shunn and Monique Patenaude, and that Reed and his brother, Tony, hid the bodies along a remote logging road before fleeing to Mexico. John Reed is due to face trial next year; his brother has been sentenced to 14 months after pleading guilty to helping hide the bodies.
