Tiffany Goruk and her boyfriend Jeremy Snow were murdered this week.

Police have painstakingly followed the path taken by a suspected killer but want more witnesses to come forward.
Forensic experts have combed the West Kelowna route for evidence after Tiffany Goruk and Jeremy Snow were found dead in Goruk's vehicle Monday night.
A man was seen running from the Cadillac Escalade after it crashed into a wall. A sniffer dog that followed his track 30 minutes later lost the scent by the Mount Boucherie complex.
"We're looking for witnesses who may have seen this individual and the route he took. What did he touch? There could be physical evidence he left behind," said RCMP Cpl. Dan Moskaluk.
People told police what they knew soon after the couple was murdered and a tip line launched Wednesday has attracted more information. Investigators say the suspect travelled southwest on foot via Bentley and Daimler roads to Bylands, across Highway 97 to the Ross Road area near the Petro-Can and past a hotel. They don't know his exact route.
Moskaluk wouldn't say how many officers are working on the investigation but said RCMP have dispatched "a proper amount of resources." And he cautioned against reading too much into how little information they've disclosed.
"The lack of plentiful detail or information being released isn't indicative of how well the investigation is going. Each case is unique."
Police have not released the cause of death. Autopsies have been ordered but there's no word on when they take place.
Friends say Goruk, a 30-year-old mother of two, was an innocent bystander when Snow, a convicted drug smuggler, was killed.
The tip line is 1-888-688-4264.
