Three men and a woman are facing charges, including child endangerment, after drugs and money were found in three north Edmonton homes, one of which had three children inside.

The Alberta government is launching an "internal review" to look into its mental health and child intervention systems regarding the case of a 15-year-old boy who's been charged with attempted murder after an Edmonton bus driver was viciously attacked last month.

An Alberta law that fines or imprisons people who don't report cases of child abuse or neglect has never been used, something advocates say is a "lost opportunity.''
