She is 15 years old.. The girl behind the school shooting in Wisconsin

American police said that a 15-year-old girl was the one who opened fire last Monday at a private school in Madison, Wisconsin, killing two people, in addition to the girl herself.
Madison Police Chief Shawn Barnes said the girl injured six others in a shooting at Abundant Life Christian School, including two students who were in serious condition.
The police are trying to determine the reason that led to the shooting.

Interrogation of the girl’s family

Barnes said that police are speaking with the shooter’s father and members of her family, noting that they are cooperating, and police have also searched the shooter’s home.

CNN quoted Barnes as saying that they are trying to set a schedule for the last hours before the attacker goes to school.
He added that they asked the office responsible for firearms to quickly determine the source of the weapon used in the shooting, and how a 15-year-old girl obtained it.
He indicated that he was not sure whether the gun belonged to her parents or not.
