A woman is dead and a man is in hospital with gunshot wounds following a violent home invasion in Markham Monday night.

York police were called to a home at 238 Helen Ave. near Kennedy Road and Highway 407 at about 10:30 p.m. after receiving a 911 call.

Police say three armed suspects forced their way inside the home, before shooting a 53-year-old mother and a 57-year-old father inside. The victim's 24-year-old daughter was separated from her parents and tied up.

The suspects initially confronted the victims and demanded money. Then, the parents were shot several times. The suspects spent about 30 minutes in the house looking for cash and other valuables before leaving. The father managed to get to a neighbouring home for help.

Emergency crews arrived to find the mother – Bieh Ha Pan -- without vital signs and her husband -- Huei Hann Pan -- with gunshot wounds. Their daughter was not hurt and the father was taken to hospital where he remains in serious condition.

The family had immigrated to Canada from Vietnam and also have a son, who was not home at the time of the attack.

Police are looking for three suspects in connection with the home invasion. The first suspect is described as a black male, 28 to 33 years of age, five-foot-six to five-foot-seven with long dreadlocks. The second suspect is described as a black male, about 31 years of age, five-foot-seven to five-foot eight in height with a thin build. His face was covered with a bandana. The third suspect is described as a thin male who spoke with a Caribbean accent. The first two suspects were wearing dark clothing.

Investigators have released security footage from the street, and are appealing to anyone who recognized the vehicle to contact police.

The video shows that the suspects may have entered the home through the front door. Police believe the incident was random attack.

Residents are being reminded to keep their doors and windows locked at all times, and to not answer the door if they don't know the visitor.

Anyone with information is asked to call York Regional Police at 1-866-287-5025 x. 7865 or Crime Stoppers anonymously.
