Ryan Lanza, brother of Connecticut gunman, 'extremely cooperative' with investigation
A law enforcement official briefed on the investigation of the Connecticut school massacre says the brother of the gunman has been "extremely cooperative" and is not under arrest.
The official tells The Associated Press that Ryan Lanza, of Hoboken, N.J., is still be being questioned but is not in custody and is not believed to have any connection to the school killings.
The official spoke on condition of anonymity because he was not authorized to speak publicly on the investigation.
The official says Ryan Lanza's computers and phone records were being searched but only "in an abundance of caution." He says Ryan told authorities he had not been in touch with his brother in recent years.
His brother, 20-year-old Adam Lanza, opened fire Friday inside two classrooms at the Connecticut elementary school where his mother was a teacher, killing 26 people, including 20 children, as youngsters cowered in corners and closets and trembled helplessly to gunshots reverberating through the building.
Carrying two handguns, Adam Lanza committed suicide at the school, and another person was found dead at a second scene, bringing the toll to 28, authorities said.
Police shed no light on the motive for the attack.
The gunman was believed to suffer from a personality disorder and lived with his mother in Connecticut, said a law enforcement official who was briefed on the investigation but was not authorized to publicly discuss it.
