Strathcona County RCMP have seized a pickup truck thought to have been involved in a weekend hit-and-run at a Sherwood Park gas bar that left an employee with serious injuries.

The truck was found at an undisclosed location in Sherwood Park at 7 p.m. on Sunday after RCMP received a tip from a member of the public, said Const. Chantelle Kelly.

The victim remains in stable condition in hospital after undergoing surgery, Kelly said.

Investigators are examining the truck and are still looking for the driver.

"[The truck is] going through our processing with the forensic identification unit, which will give us more information, some more evidence," Kelly said Monday. "But ultimately we believe that we will be able to locate the person responsible.

"We are still asking the public to come forward with any information, whether they maybe witnessed it or [can] help us identify the driver at the time."

The hit-and-run happened just before 3 p.m. Saturday at the Superstore gas bar on Baseline Road.

Witnesses said a driver — a white man in his 30s — was trying to leave without paying for gas when a male employee tried to intervene.

The employee was run over. The suspect vehicle was last seen heading west on Baseline Road toward Sherwood Drive.

Kelly said the truck seized Sunday matched the description of the suspect vehicle — a 2000-2008 silver Dodge Ram with extended tow mirrors, black after-market rims, lowered trailer hitch and decals in the rear window.

Police don't believe the truck had been stolen, Kelly said.
