Police are looking for the driver of a jeep involved in a fatal single-vehicle crash along Gateway Boulevard that killed a passenger.

28-year-old Ryan Richard Wilneff, from Nova Scotia, walked away from hospital after being admitted for injuries sustained in a collision last Wednesday on Gateway Boulevard.

Police say the incident occurred at 2 a.m., when the jeep Wilneff was operating reportedly veered off the road between 60 and 61 Avenue. The Wrangler knocked down a light standard and continued through a parking lot - striking several billboards and trees - before crashing into the wall of a business.

Wilneff sustained non-life threatening injuries in the crash and a 28-year-old male passenger was killed.

Alcohol and speed were believed to be factors but at the time, there were no arrests or charges.

Two days after the collision, Wilneff - who wasn't being guarded - walked out of hospital.

"Based on our experience these people are admitted to hospital and somewhat immobilized, and we had information that they would be there for several days," said EPS Constable Rick Wever.

Police aren't releasing which hospital he was being treated at.

"It's obviously very disappointing that he discharged himself, in a perfect world this doesn't happen, but there's really nothing stopping him from getting up and walking away, and we were quite surprised he was able to do so," said Wever.

A provincial warrant was issued the day he left hospital, but police say it wasn't made public for investigative reasons. Since Wilneff is from Atlantic Canada, on Thursday, the warrant was extended country-wide.

"He does have heavy ties to Nova Scotia," said Wever. "He hasn't been out here very long."

Wilneff faces charges of impaired operation causing death, dangerous driving causing death, possession of a controlled substance, and four breach of probation orders.

Anyone with information on Wilneff’s whereabouts is asked to contact EPS at 780-423-4567 or #377 from a mobile phone. Tips can also be submitted anonymously at 1-800-222-8477 or online.
