Investigators are now looking at the possibility of charging 50-year-old Daniel Tschetter with impaired driving, careless driving and criminal negligence.
Over the next few days, officers will be doing a thorough search of the cement truck as it sits in the police traffic office in northeast Calgary.
Officers say they have numerous witnesses reporting that the truck was driving erratically in the minutes leading up to the crash.
At the scene Tschetter performed a breath sample but police say he didn’t provide a reliable sample.
Police are also working on a timeline so that they can determine exactly when Tschetter left his jobsite near High River and whether he made any stops before arriving at the intersection.
