A London couple charged with keeping their nephew locked in a disgusting bedroom for up to two years will be sentenced Sept. 21.

This came following an emotional day in court Tuesday, where the gruelling and horific facts of the case were read for the record.

The Crown is asking for jail time for the pair, while the defence is asking for house arrest.

A victim impact statement was also read into the record by the boy at the centre of the case.

The pair, who can't be identified to protect the identity of the victim, plead guilty in May.

The couple was arrested in May, 2014, with London police telling a news conference afterward that the case was “horrific.”

They said a member of the public made an anonymous tip to the Children’s Aid Society, asking them to check on the welfare of a child at the home. After the home’s occupants refused to answer the door, police were called to enter the home.

Once inside, they discovered a malnourished and pale 10-year-old boy in what they described as a “squalid” master bedroom.

The room was filled with garbage, feces, and a urine–soaked bed. The boy appeared “confused and upset” when authorities arrived.

Police said they believed the boy had been held in the room for 18 to 24 months and had been fed fast food, only twice a day.

They said they also believed the child had never attended school.

The boy was taken to hospital and after being treated for malnutrition, was placed in a foster home, where police said he immediately thrived.

The aunt and uncle also had a nine-year-old daughter of their own.

She was also placed into foster care after her parents’ arrest.

Police said the girl had been allowed to attend school and had never been confined in the home.

It appeared that the girl was unaware that she had a cousin being held in the home.

The boy came to Canada from South Korea in 2010 to visit the aunt and uncle, who moved to Canada in 1997.

Police later learned the boy’s father had not been able to financially support his son and made the decision to send him to relatives in Canada.
