In the wake of the mass killings at Sandy Hook Elementary School, FRONTLINE investigates a young man and the town he changed forever. Adam Lanza’s motives, and his life, remain largely a mystery. With The Hartford Courant, FRONTLINE looks for answers to the central — and so far elusive — question: Who was Adam Lanza? Also this hour: In the aftermath of the tragedy, President Obama called for a national conversation about guns. Nowhere is that conversation more intense than in Newtown, where FRONTLINE finds a town divided and explores how those closest to the tragedy are wrestling with our nation’s gun culture and laws.
Frontline's "Raising Adam Lanza" can be seen on Wednesday, February 21st at 7 pm.
