Local police in Fenxi county, Shanxi Province, said late Tuesday that the suspect who gouged out the eyes of a 6-year-old boy was his aunt.

Zhang Huiying, 41, the aunt, killed herself by jumping into a well located in the courtyard of her own home on Friday.

She was announced to be the suspect after a series of lab tests which confirmed the woman's DNA at the scene.

The police also found blood stains that are identified as belonging to the boy on Zhang's clothes.

The boy was found unconscious near his home late night August 24. His eyeballs were found at the scene but the corneas were gone.

The boy said that a woman with a non-local accent called his name and asked him if anybody in his home played mahjong before taking him to the field, according to his mother Wang Wenli.

Local police immediately launched a manhunt for the suspect by offering a 100,000 yuan ($16,335) reward for information leading to the arrest of the suspect, whom they said was a woman.

The police ruled out the possibility of organ trafficking.

The boy is still under medical treatment, and has not been told of his permanent loss of vision yet. The reason behind the attack remains unknown.
