The driver of a car that hit two cyclists on Highway 99 in May, killing both of them and a passenger, has been arrested and is facing numerous charges.

RCMP arrested Samuel Alec, 43, on Aug. 14. He has been charged with three counts each of criminal negligence causing death, impaired driving causing death, and driving with a BAC over 0.08. He was also charged with failing to remain at the scene of the accident.

On May 31, RCMP say a car struck and killed cyclists Ross Chafe, 52, and Kelly Blunden, 53, on Highway 99 north of Pemberton around noon.

A passenger in the car, Paul Pierre Jr., 52, a well-known local rancher, also died at the scene.

Friends said Blunden was a long-time member of the Whistler Cycling Club who would take beginners out for rides and also helped manage the club's website.

Chafe was described as an experienced cyclist who had only lived in Whistler for two years. He worked for Flags Unlimited, an Ontario-based company that designs flags and banners.

RCMP say Alec was taken by helicopter to a hospital in Vancouver and appeared to have been impaired, based on observations from witnesses and officers at the scene.

Highway 99 was closed in both directions for nearly 10 hours the day of the collision. 

Alec is expected to appear in North Vancouver court on Aug. 17 at 9:30 a.m.
