A 76-year-old man was arrested for murdering his wife in a hammer attack after he revealed the brutal killing over a dim-sum breakfast with his son yesterday.
An initial investigation showed the man's wife, Lai Sau-fong, 78, was bludgeoned to death at home in Wong Tai Sin on Monday night during a dispute.
The city's second murder case in four days came to light when police received a call from the couple's son yesterday.
"The elderly man called his son around 8.30am, saying all his problems would be solved if he died and that he wanted to commit suicide," a police source said.
"His son then comforted him and invited him for a dim-sum breakfast. He revealed the killing when they met at the restaurant."
The 46-year-old son then called police and took officers to the couple's flat on the 14th floor of Wang Cho House, Wang Tau Hom Estate, where Lai was found dead in bed. Police arrested the elderly man for murder.
"The elderly woman had suffered six to seven heavy blows to the head," superintendent Chow Tak-choi, assistant commander for Wong Tai Sin district, said, adding that the woman died from her injuries at about 10pm on Monday. "The couple had a heated argument over money and the woman was attacked with a hammer and killed."
Chow said there were signs of fighting in the flat and there was blood on the walls. "A hammer was found in a toolbox in the kitchen and it is believed to have been used as a weapon," he said.
The suspect was being held for questioning last night and had not been charged. Chow said police had not received any reports of domestic violence involving the couple. They lived on welfare payments and their children had moved out.
It is the city's second murder case in four days. Last Friday, a 47-year-old man was stabbed to death in an attack at Mun Hau village in Sheung Shui. Police arrested a 54-year-old man and seized a fruit knife from his bag that was found nearby.
Police figures show there were 62 homicide cases last year. That includes 39 deaths in the 2012 Lamma ferry tragedy, which were ruled to be homicide last year. There were 27 reports of homicide in 2012 and 17 in 2011.
