MEXICO CITY (AP) — Mexican authorities on Friday announced the discovery of bodies and remains in the northwestern state of Sinaloa in an area of an ongoing search for 10 missing workers from a Canadian gold and silver mine. The statement from the Mexican Attorney General’s Office did not specify how many bodies or sets of remains were found, but said that one of the bodies had the “characteristics of one of the people reported as missing.” The office also reported the arrests of four people believed to be tied to the workers’ disappearances. The Sinaloa state prosecutor’s office said the remains were found in the community of El Verde, in the municipality of Concordia, where the mine is located.
