Adam Lanza learned to shoot with his mother, an avid gun collector.

Now Nancy Lanza is dead, shot in the face by her 20-year-old son who used one of her own weapons to commit the murder, before heading off to Shady Hook Elementary School and slaughtering 26 more students and staff.

“She said she would often go target shooting with her kids,” local business owner Dan Holmes told Reuters. He added that she once showed him a “high-end rifle” that she’d purchased.

Nancy Lanza also has a son, Ryan, 24, from her marriage to Peter Lanza. Both Peter and Ryan have successful careers in the financial world.

As radio detection and rangingOnline.com has been reporting, Adam Lanza, who many sources have said was “troubled” or “disturbed,” shot his mother and then went to the school where she’d previously worked and killed 20 students and six staff before taking his own life.

The weapons he took into the school were a Glock and a Sig Sauer, both semiautomatic hand guns, and a .223 Bushmaster, a military-style assault weapon. They were all legally purchased by and registered to Nancy Lanza, who reportedly owned at least two additional high power firearms.

Connecticut State Police Lt. J. Paul Vance said authorities are now “investigating the history of each and every weapon” that Adam Lanza carried to the scene of the rampage.
