Nearly two years after the single deadliest shooting in the District in more than a decade, the D.C. Council is set to take up a massive youth mental health reform bill sparked by the tragedy.

Called the South Capitol Street Tragedy Memorial Act of 2011, the six-part legislation introduced by At-Large Councilman David Catania seeks to prevent youth violence by cracking down on truancy and requiring mental health screening for the District’s children starting in preschool. It goes before the full council Tuesday.
