Two people are dead and another person is in serious condition after a hit-and-run accident in Coquitlam, B.C.

Police say the accident happened at about 12:30 a.m. PT Saturday on Lougheed Highway when a Good Samaritan stopped to help two stranded motorists.

"There was an accident with a male and female inside [a car] and a Good Samaritan stops to help and is finding out if everyone’s OK when another car comes through … and kills two people and seriously injured another person and takes off and doesn’t even stop and give assistance," said Coquitlam RCMP Staff Sgt. Mark McCutcheon.

Police later found the vehicle in the Cape Horn area, McCutcheon said, but the driver was gone.

"We’re currently looking for the driver of that suspect vehicle, a ’95 white Jeep Cherokee, and we’re appealing to him to do the right thing and turn himself in to police," he said.

"You know, this is a tragedy. A Good Samaritan who stopped to help is killed and then another female is killed as well."

The identity of the two victims has not been released.

The injured victim is in serious condition at Royal Columbian Hospital in New Westminster.
