Shocking details of how a former student from a top Chinese university allegedly killed his mother in 2015 - and then kept her rotting corpse from being discovered as he evaded the police for nearly four years - surfaced after his arrest on April 20.

The man, now 24, managed to keep his whereabouts under the radar with the help of more than 30 ID cards and was finally caught with the assistance of the latest crime-fighting technology - facial recognition.
