A former Edmonton foster mom accused of killing a little boy in her care has been found guilty of manslaughter.

Lily Choy arrived in court Wednesday afternoon to hear the verdict in her second-degree murder case.

She is on trial for the second time after an earlier conviction for manslaughter was overturned by the Court of Appeal due to incorrect instructions from the judge when the dead-locked jury continued deliberating.

Choy was charged after the three-year-old boy died of a head injury in her home in 2007.

"This is just another example of a person who should never be around children for the rest of her life," said Det. Bill Clark, with the Edmonton Police Service.

Crown witness allegations stated she would make the boy stand in the corner for hours at a time, put him in a cold garage in winter with only a soiled diaper as clothing when his crying kept her children awake.

This second trial contained many of the same allegations, and medical experts on both sides. The Crown said Choy's form of disciplining the child was responsible for the boy's head injuries in the washroom of her home. The defence said that the boy was aggressive and his own behaviour, actually caused his fatal injuries.

This time around, Choy's case was heard by judge alone.

Madame Justice Donna Reed brought up the other injuries that doctors found on the boy, which included multiple bruises around his body.

She said the only person she believed who had opportunity to cause those injuries was Lily Choy.

There is no minimum sentence for manslaughter. Choy will be released until sentencing begins on Oct. 17th.
