Four fatal shootings in B.C.'s Lower Mainland since Christmas Eve are not related and none of the incidents appears to have connections with organized crime, police say.

Supt. Dan Malo of the Integrated Homicide Investigation Team made the assertion at a news conference Tuesday in Surrey near the scene of the latest killing.

With the lack of any link among the slayings or any connection to gangs, Malo said he wanted to reassure the public there was no reason for fear or panic on the streets.

Five people have been shot in total since early Saturday, with a 54-year-old woman being the only victim who has survived.

The two latest shootings took place in Langley and Surrey.

"The four years I've been here this is extremely unusual ... like I've never heard of this happening before," Staff Sgt. Bruce Anderson said in an interview earlier Tuesday.

"What the reasoning is, or if there is a specific reason, it's unknown at this time. But this is unheard of."

9500 block of 125 Street, Surrey, B.C. Police said a 38-year-old man was pronounced dead in his Langley driveway Monday night, and a man in his 20s was found dead in Surrey on Tuesday morning.

Sgt. Jennifer Pound, of the Integrated Homicide Investigation Team, said in a news release that just after 9 p.m. Monday police received a call of shots fired at a Langley home.

She said police and members of the B.C. Ambulance Service responded and found an unresponsive 38-year-old man bleeding in his driveway. Pound said the man was pronounced dead at the scene.

Surrey RCMP later received reports around 8:30 a.m. Tuesday that a man was lying on the lawn of a north Surrey home, and that the owners of the residence had heard shots about an hour earlier.

Police arrived to find a Caucasian man dead on the ground in a hedge area near the road.

Plain clothes officers and homicide investigators were called in to probe the incident.

Anderson said the man appeared to have been targeted.

1st incident occurred Christmas Eve

The string of shooting deaths in Metro Vancouver began early Dec. 24 when Bradley McPherson was gunned down outside a Surrey house party.

The second death came on Christmas Day when convenience store employee Alok Gupta, who volunteered to work so the shop owners could enjoy the holiday, was killed.

Meantime, a 54-year-old woman who suffered a gunshot wound to the chest at a north Surrey apartment early Sunday has not been identified by police. Her injuries were not believed to be life-threatening and police have not revealed her identity.

Pound said Monday that police do not yet have any suspects.

Police are asking anyone with information on any of the incidents to call B.C. Crime Stoppers.
