Long-lost jawbone of U.S. Marine discovered in Arizona child's rock collection

Experts have identified a human jawbone found in a child's rock collection as belonging to U.S. Marine Corps Captain Everett Leland Yager, who died in a 1951 military training exercise. The jawbone, discovered in Arizona, was linked to Yager through genetic genealogy testing performed by college students and a high school intern, making the intern potentially the youngest person to help solve such a case. The bone's presence in Arizona remains a mystery, with one theory suggesting it may have been carried there by a scavenger such as a bird.
