An eight-year-old found dead in the trunk of her mother's car had been smothered, a New Westminster court heard Tuesday.

Almost four years after Lisa Batstone's daughters death, her second-degree murder trial began Tuesday. 

The Crown intends to argue Lisa Batstone of Surrey smothered the child over resentment toward the father following a divorce.

Teagan's body was discovered Dec. 10, 2014, and Batstone was charged with second-degree murder.

A forensics officer testified Tuesday that a note was found in Batstone's home that said "I'm sorry" along with a plastic bag with duct tape around it.

Batstone had regained custody of Teagan following a suicide attempt in 2012.

Her father, Gabe Batstone, had moved to Ottawa with his new wife, but visited Teagan just days before her death.
