Serial killer gets death penalty for 11 murders

"He's very cold-blooded and shows an antisocial personality," he was quoted as saying by the Beijing Times.

The serial killings aroused huge public outrage when the murders occurred, but Gao was not a suspect in the crimes until 2016, after police collected a blood sample from a relative of Gao in another criminal investigation in 2015. Thanks to the development of DNA technology, police were led to Gao by a DNA comparison, and he was arrested in a grocery store in a school in Baiyin on Aug 26, 2016.
