The foster parents of seven-year-old Katelynn Sampson were ordered Monday to stand trial in the little girl's death.

Sampson's death shocked Toronto during the summer of 2008, when detectives who found her body said her injuries were the worst they'd seen in similar circumstances.

Her body was found a Parkdale apartment building where she lived with a foster family.

Donna Irving and Warren Johnson have been ordered to stand trial on first-degree murder charges following Monday's preliminary hearing. They are expected to be back in court May 19.
