Opening statements at the trial of Daniel Tschetter began Monday morning with disturbing allegations.

Tschetter was driving a cement truck that plowed into the back of a car stopped at a red light at the intersection of Macleod Trail and 194 Avenue S.E. in December 2007.

Five people in the car were killed.

Chris Gautreau, 41, and his daughters Alexia and Kiarra, Gautreau's girlfriend Melaina Hovdebo and her 16-month-old son Zachary, all died at the scene.

Prosectors say Tschetter was driving at frightening speeds when he ran into the car.

The Crown says that after the crash, Tschetter threw a bottle of vodka into the back of his cement mixer.

Prosector Jonathan Hak also told the court that two drivers had called 9-1-1 to report the truck driving at unsafe speeds.

He also said the light had been red for some time and the truck didn't slow down before hitting the stopped car.

The trial continues Monday afternoon.
