An ongoing investigation into the death of 29-year-old John Stanley Kwiatkowski has uncovered significant new evidence that police say has moved the investigation forward.

Just after 6 a.m. on April 14th, 2011, Kwiatkowski's wife returned from a night-shift at work to the couple's home on 34 Street and 103 Avenue near Rundle Park, and discovered the body of her common-law husband.

She also found their two-year-old daughter, and it's believed she was present while her father was attacked and killed.

Police said he had been brutally attacked and murdered in the home overnight - investigators later confirmed his death as a homicide.

A 10-month investigation has revealed what police say is key evidence in the case.

Investigators have connected a stolen Jeep Cherokee to the murder. Police believe that at the time of Kwiatkowski's murder, at least one of the people responsible for his death was in the vehicle.

Inside the vehicle were several items stolen from the murder scene, including a video camera owned by the family. Also found in the Jeep was pair of Nike high-top runners stained with Kwiatkowski's blood.

Investigators also pointed to a soft drink can, for Canada Dry Ginger Ale, which forensics found had not been used by either the victim, or his wife.
