That’s when the Ramapo college students and a excessive school-aged intern — the youngest particular person identified to have ever contributed to an IGG case — stepped in.
In simply two days, they tracked down a “lead candidate” who intently matched the DNA profile of the jawbone, who as luck would have it, was the soldier’s daughter.
Final month the outcomes of a DNA pattern they collected from his daughter, whose title was not given, confirmed the Ramapo group had cracked the case: the jawbone was actually Yager’s.
The Marine captain was killed in July of 1957 when his airplane crashed throughout a coaching train in Riverside County, California.
