(CNN) - The three weapons found at the scene of Friday's Connecticut elementary school shooting were legally purchased by the suspected gunman's mother, Nancy Lanza, a law enforcement official familiar with the investigation told CNN.
A Glock and Sig Sauer were found inside the school with the deceased gunman, 20-year-old Adam Lanza, while a Bushmaster rifle was found in a car outside the school, the official said.

Little is known about Lanza's life before he burst into Sandy Hook Elementary School in Newtown, Connecticut, dressed in "black battle fatigues and a military vest" and began firing, according to a law enforcement source. By the time he was done, 26 were dead -- 20 of them young students.
The bloodshed ended when Lanza's own life did. He was found dead in a classroom with two firearms, a Glock and Sig Sauer. Another gun, a 223 Bushmaster, was found nearby in a car.
The massacre left people in the Connecticut community, around the country, around the world asking questions. Who was this man, and why did he do this?

As of early Friday evening, authorities had offered few details about Adam Lanza. He had no known criminal record, a law enforcement official said.
Beth Israel said her daughter was in the same class at Newtown High School with Adam Lanza, who lived six houses away.
"He was troubled for sure for a long time," Israel said on Twitter.
