Jonathan Pratt, the man accused of impaired driving in a crash that killed three people near Beaumont in 2011, will learn the outcome of his trial on Thursday.

On Tuesday, his lawyer Timothy Dunlap argued that the Crown had not proven beyond a reasonable doubt that Pratt was driving the truck that slammed into a Grand Am carrying Bradley Arsenault, 18, Thaddeus Lake, 22 and Kole Novak, 18.

While Pratt admits he owned the truck,  Dunlap suggests that someone else was driving that night, he argued.

Pratt was lying beneath the truck when police found him at the crash scene and no one ever saw him behind the wheel.

Pratt's blood was found on airbags on both the passenger and drivers sides.

Crown prosecutor Gordon Hatch has told the court there was no evidence showing a “phantom driver” and there were no footprints in the snow leading away from the truck.

Police have testified that only Pratt and the three dead men were found at the scene.

But Dunlap believes they didn’t do enough work to find another person who may have been driving the truck.

Pratt faces three counts each of impaired driving causing death, driving with a blood-alcohol content over .08 causing death and manslaughter.

The judge will deliver his decision Thursday in Wetaskiwin.
