OLYMPIA, Wash. (AP) — Washington’s Supreme Court has unanimously struck down the drug possession convictions of a man who was detained at a U.S.-Canada border crossing for five hours without being advised of his rights. Alejandro Escalante was returning with friends from a music festival in Canada in 2017 when border guards at the Frontier crossing, north of Spokane, stopped them for inspection. The guards kept Escalante in a locked lobby for hours as they searched their van and found a backpack with a small amount of heroin and LSD. Escalante admitted the backpack was his. The court said that statement should have been suppressed at trial because he wasn’t advised of his right to remain silent.
