Prosecutors in the western Mexican state of Jalisco have confirmed the discovery of many clothing items and bone fragments by a group of people searching for relatives at a previously known cartel training site.

For the investigators, the human foot -- burned, but with some fabric still attached -- was the tipoff: Until recently, this squat, ruined house was a place where bodies were ripped apart and incinerated, where the remains of some of Mexico’s missing were obliterated.
