Final Update: A number of things about our previous story are proving to be erroneous as more details about the shooting today in Newtown, Connecticut comes to light. Here is what we know so far:
Adam Lanza, and not Ryan Lanza (his older brother) has been identified as the shooter. His brother Ryan Lanza, who lives in Hoboken, New Jersey is being questioned by police. Lanza's father, who lives in Connecticut, was similarly questioned, one of the law enforcement officials said.
