Live Chat: Who is Adam Lanza?

How do you make sense of a seemingly senseless act of violence? How do you help the country begin to process the trauma of 20 small children shot dead in their classroom?

In the wake of the mass killings at Sandy Hook Elementary, FRONTLINE and The Hartford Courant’s jarring documentary “Raising Adam Lanza” tackles those questions in an investigative look into Adam Lanza’s childhood and life before the Newtown shootings.

Today at 2 p.m. ET, FRONTLINE is hosting a live chat featuring the film’s producer Frank Koughan, Hartford Courant reporters Alaine Griffin and Josh Kovner, and Liz Goodwin, national affairs reporter for Yahoo News.
