Impairment ruled out as cause of fatal Surrey crash

The B.C. Coroners Service has ruled out impairment by drugs and alcohol as the cause of a tragic automobile crash that killed five members of one Surrey family and the driver of another car.

"Toxicology results received from the Provincial Toxicology Centre show no indication of impairment due to alcohol, illicit drugs, or prescription or over-the-counter medications in the blood of Daniel Mark Gore," said a statement issued by Coroner Barb McLintock.

Gore, 46, from Surrey, was the driver and sole occupant of a mini-van that hit a car broadside at the intersection of 32nd Avenue and 176th Street on April 28, killing the five occupants of the car.

With impairment ruled out as a factor, the coroner's investigation into the cause of the collision is continuing, said McLintock.

"Mr. Gore died in hospital seven days after the crash. During his time in hospital, he was diagnosed with a serious medical condition unrelated to the injuries he sustained in the MVI," said the statement.
