KOFU--Yamanashi prefectural police on May 12 said tests on a bone found in a mountainous area of Doshi showed it likely belonged to a schoolgirl who went missing in 2019 on a family camping trip. 

Police studied the mitochondrial DNA of cells in part of the skull found by a volunteer on April 23 who was helping in the search for Misaki Ogura, the missing 9-year-old girl from Narita, Chiba Prefecture.

The lab tests found no discrepancy between the cells and a blood relative on the girl’s mother’s side.

Yamanashi police conducted a DNA test on the skull but could not identify the individual, leading to the study of the mitochondrial DNA, which is inherited exclusively from the mother.
