CALGARY - The father of a toddler who was killed when a cement truck driver slammed into a car at a Calgary intersection says he visits his son's grave every day and looks at the picture on his tombstone.

Zachary Morrison's dad is one of several people giving victim impact statements at the sentencing of Daniel Tschetter on five manslaughter convictions.

Tschetter was found guilty by a judge earlier this year in the deaths of two adults and three children, who were in a car waiting for a red light in December 2007.

He was driving erratically and speeding when he hit their car so hard he demolished it beyond recognition.

Lee Morrison says he's trying to move forward to give his son's brief life some meaning, but is constantly reminded of his loss when he sees other families with their own children.

The courtroom has been filled with the sobs of the victims' loved ones, and Tschetter, too, has appeared incredibly upset.
