'I'll gut you like a fish': Daughter testifies Greg Fertuck had history of threats against her mom

Lauren Fertuck says her mom, Sheree, confided the dark details of her collapsing marriage as the pair shared the cab of Sheree's semi-truck while hauling gravel through rural Saskatchewan.

These intimate mother-daughter conversations took place in the two years before Sheree disappeared on Dec. 7, 2015.

"On the semi rides we'd talk about my dad and the shit he was doing, how he was abusive to her and me and my sister," Lauren testified on Wednesday at her father's trial for first-degree murder.

"She told me that she was scared that my dad would do something. She said, 'If anything happens to me, look at your dad. And take care of my dog.'"

Greg Fertuck is now on trial at Court of Queen's Bench in Saskatoon, accused in Sheree's death. Her body has never been found, but her semi-truck was found abandoned in a gravel pit near Kenaston, Sask., on Dec. 8, 2015.

He has pleaded not guilty to the first-degree murder charge.

Lauren Fertuck was 14 years old in 2010, when Greg and Sheree's marriage began falling apart because of his drinking and gambling, she testified by video.
