Amanda Trevors, the mother of Natalia Shingoose, gave emotion-filled testimony Thursday at the trial of Adam Cyr, the 34-year-old Regina man accused of killing the toddler.

"You're a bastard," Trevors said from the witness box, directing the comment at Cyr, as she told jurors details about how she found the lifeless child in a bedroom on the morning of June 21, 2012 in Regina.

She recalled that in the morning, as she arose, she hadn't heard stirring from the child — described as rambunctious and full of energy in earlier testimony — and thought that was unusual.

Shingoose was just a few days shy of her third birthday. Trevors and Cyr were in a relationship at the time.

Trevors said when she went to her daughter's room she found Shingoose with a swollen face and the girl's body felt "frozen".

Trevors recalled a frantic call to 911. Cyr, she said, had been taking a shower and came out while Trevors called 911.

"Somebody had to help my baby," she said. "Somebody had to help her be OK."

Trevors said it was a devastating experience.

"Nobody should have to feel their baby like that," she said. She told the jurors that as the child's body was taken away, she tucked a teddy bear with her, "so she wouldn't have to be alone."

Trevors also testified about the reaction she saw from the accused.

She said that Cyr told her he expected the two of them would become suspects in the child's death.

When asked if she hurt the girl, Trevors responded, "No. I love my baby."

The jury also learned that items found by police in an garbage container — a pillowcase, blanket and the child's jacket — were not thrown out by Trevors and that she did not ask anyone to put them in the trash.

Trevor's testimony, which took over four hours, included information about the previous night and how she had arrived home, from her work, around 9 p.m. CST. Cyr had been baby-sitting that day and Trevors said that he was good with her two children.

She said Shingoose was lying in her bed and Trevors thought the girl was sleeping so she turned off the TV in that room and closed the bedroom door.

She also told the jury that a close friend of the family, Matt Bennett, came into the home around 3 a.m., and told her that their front door was open. Trevors testified that it was unusual for the front door to be that way and said she did look into her daughter's room and saw Natalia in the same position from earlier. She testified that the child's bedroom was open at that time, even though she had closed it earlier.

Under questioning from the Crown prosecutor, Trevors also said that, in the past, she had dealt cocaine but stopped that in 2011. She also said she was drinking a lot in the summer of 2012 and could go through an 18-pack of beer in two or three days.

She said she wishes that she had checked on her daughter more closely on the night and morning before Shingoose was found dead.

The trial continues. Cyr is charged with second-degree murder.
