Jealous man admits stabbing to death neighbour he suspected of having affair with wife

A jealous husband stabbed a neighbour to death after becoming convinced he had been having an affair with his wife for 20 years, the Court of First Instance heard on Tuesday.

But as police later found out, Chung Siu-ping’s wife had never had sex with victim Lau Kei-king, 74, and Chung’s jealousy only came from his delusion, the court heard.

Chung, 66, pleaded guilty to one count of manslaughter before Deputy Judge Michael Stuart-Moore. The judge adjourned sentencing to November 28 pending updated reports from two psychiatrists.

Prosecutor Andrew Bruce SC told the court Chung and Lau had lived in Tai Hing Estate, Tuen Mun, for over twenty years. Their flats were just across the corridor from each other.

On October 5, 2011, residents on the same floor heard noise from the corridor, and came out to see Chung using a knife to stab Lau.

Lau suffered 16 wounds on his head and neck, and some more cuts on his torso where the knife had penetrated into his chest, liver and intestines. He was taken to hospital but died upon arrival.
