According to the police, Narender Singh arrived at his in-laws' house in Sector 30 of the city on Wednesday night and went to sleep after having dinner.
Singh's wife Chranjeet Kaur alias Nikki was living with her parents following some dispute with her husband.
Singh hailed from Punjab's Amritsar and was into the cable business in Chandigarh.
Deceased Nikki's mother told the police that the couple got married four years ago and had two children -- a three-year-old daughter and a one-year-old son.
"Singh was an alcoholic and used to beat up Nikki. Following regular torture, my daughter had started living with us for the last few months," the deceased's mother told the police.
Nikki was shot at on Thursday while washing clothes.
"After shooting at his wife, the accused also shot himself. Singh died on the spot while his wife succumbed to her injury on the way to hospital," a senior police officer said.
He said that a countrymade pistol and cartridges were recovered from the scene of the crime.
"We are trying to find out the exact cause behind the killing of his wife and the extreme step taken by the man," the officer added.
