Mass murderer  in the Sandy Hook Elementary tragic shooting , Adam Lanza learned everything he knew about firearms from his  first victim, Nancy Lanza, his mother.

Adam’s first victim was his mother, Nancy. She was reportedly a collector of weapons according to TMZ. She took her son to many firing ranges to teach him how to shoot.

Dan Holmes,  a neighbor of Nancy said, “Nancy was a gun enthusiast … an avid collector … often taking her kids to the gun range, infusing them with her obsession with firearms.”

Adam used several different types of guns when he opened fire on Sandy Hook Elementary school earlier this week. All of the deadly weapons were all registered in his mother’s name.
