City cops are investigating the events prior to a fatal crash that left five dead Friday night, including three children.
Police are searching for evidence that would suggest the driver had been drinking alcohol prior to the wreck.
On Friday around 7 p.m. a cement truck was reported to have been driving erratically on Macleod Trail northbound before plowing into a 1999 Chrysler Intrepid at the 198 Ave. intersection.
Duty Insp. Guy Slater said the behaviour of the driver at the scene prompted police to ask for a breathalyzer sample, but the driver refused.
Slater added that police will look into the time before the accident to find sufficient evidence to prove if the driver was under the influence.
Police have charged 50-year-old Daniel Tschetter of Cochrane with five counts of dangerous driving causing death and refusal to provide a breath sample.
