'Disturbing' details surround case of slain Toronto girl

Here's a real tragic story. Man, this is just stupidity compounded by negligence compounded with nothing short of evil. Excerpt:

"Katelynn Sampson, 7, looked as though she might have been abused for some time, police said Tuesday.
...
Ryan said when emergency workers found Katelynn's body in an apartment in the west-end neighbourhood of Parkdale, there was evidence the Grade 3 student had been sleeping on the floor and had been subject to poor living conditions that he did not want to discuss.
...
Katelynn's legal guardian, 29-year-old Donna Irving, has been charged with second-degree murder in connection with the girl's slaying. Ryan confirmed that Irving has been charged and convicted of violent crimes in the past.
...
According to Ryan, Irving was granted sole custody of Katelynn in January, although she has had contact with the girl since May 2007.
...
Child services agencies are investigating whether they played any role in placing Katelynn in Irving's care, Ryan said."
