Contrary to previous reports, the connection between the suspected gunman's mother, Nancy Lanza, and the elementary school where the shooting took place in Newtown, Conn. is still under investigation, the Associated Press reports:
A law enforcement official speaking on condition of anonymity said investigators believe Lanza attended the school several years ago but appeared to have no recent connection to it.
At least one parent said Lanza's mother was a substitute teacher there. But her name did not appear on a staff list. And the official said investigators were unable to establish any connection so far between her and the school.
