So to update what we've heard so far:
Ryan Lanza killed his brother (not his father, as reported earlier) in Hoboken; his girlfriend and another friend are missing. He drove to Newtown, Conn., where he killed a relative at a home and then went to Sandy Hook Elementary School, where he fired shots in the school office, then went to his mother's kindergarten classroom where he killed her and all her students. He then killed himself.
Lt. Vance now speaking to reporters again.
"There's a lot of things we cannot confirm or discuss as of yet."
"It is not a simplistic scene as you certainly understand. ... we are not even putting a timestamp on this as to when we will complete this project."
"The shootings did take place in one section of the school in two rooms ... our personnel our documenting the entire scene."
"Right now there is one shooter, but we're looking at every ancillary fact related to the scene."
"The medical examiner's office will certainly help us in answering many of those questions, including the manner of death of the deceased."
"We'll be back in 60 minutes ... I'll see if I can get some more answers so I can provide you with information."
"We've been asked by the family members to respect their privacy and to please leave them alone at this time."
Fox News and the New York Post are now reporting that the shooter, who is dead, is Adam Lanza, 20, while his brother Ryan, 24, is being held for questioning. Usually stories become clearer as time goes on, but this one just seems to get more convoluted.
The head of the Newtown hospital's emergency department says they've provided crisis counselors to the community.
WNBC: Related to the investigation, exit 10 on I-84 in Connecticut has been shut down for up to 12 hours.
WNBC: Two roommates of Ryan Lanza have been detained and are being questioned, but there's no indication that they had any knowledge of the events in Newtown.
Also the AP now agrees with Fox News and the New York Post that the shooter was Adam Lanza, 20, and that his older brother Ryan, 24, was arrested and is being held.
