Fox News now reporting at least 28 dead in the Sandy Hook school shootings.
AP: 27 killed, including 18 children.
Mergin Bajraliu, a student at Newtown High School, 17, has a sister, 9, who is in fourth grade at the school.
They live nearby and he heard the shots and went to the school before most of the responders arrived to get his sister, and saw a police officer carrying out a little girl whose body was limp.
“The cop was just carrying her and she was leaning back. It was very traumatizing,” he said.
State police news conference starting soon.
Shooter is being described as a 20-year-old dressed in black, possibly the father of a student, although his age seems like it would conflict with that. Was wearing a mask and had two handguns, NBC has reported.
NBC: Shooter had connections to both Connecticut, where he lived, and New Jersey.
Re: "Worst school shooting in American history," that's accurate if colleges aren't included. 32 died in the Virginia Tech shootings in 2007.
NBC: Shooter used two 9mm handguns, a Glock and a Sig Sauer.
NBC: There's a second person in custody, but it's not known if they were involved in the shooting.
Principal Dawn Lafferty Hochsprung had five children, according to a 2010 Newtown Bee story.
NBC local affiliate: Second person in custody entered the school at the same time as the gunman.
State police conference is under way.
