[2] Jensen killed his ex-girlfriend, Tabitha Stepple, and two men she was travelling with, who were part of the Lethbridge Bulls baseball team.

The couple had moved into a basement suite together, but after mounting tensions between them, they eventually split sometime around Halloween.

The two of them had a 5 a.m. flight out of Calgary International Airport for Prince Edward Island, as they were returning home for Christmas.

The four of them left Lethbridge around midnight and eventually drove north towards Calgary airport along Highway 2.

After the argument in the pub, Jensen had reportedly kept phoning Stepple and had told her "This night's not going to end well for you, I hope you know that".

Moments after leaving the store, at around 3:30 a.m., the group was travelling north on Highway 2 when Jensen rammed the back of their SUV in his car.

He was rushed to the local Claresholm hospital by ambulance and was then airlifted to Foothills Medical Centre in Calgary, but died during the transfer on the way there.

The documentary was produced and directed by Larry Day, and hosted by CTV news anchor Lloyd Robertson.
