New details have emerged about the Sandy Hook Elementary School shooting that took the lives of 20 children and six adults last December.

The Hartford Courant paints a chilling picture in describing the state of accused killer Adam Lanza's bedroom following the massacre.

Via the Courant:

Investigators who entered Adam Lanza's home after he shot and killed 20 first-graders and six adults at Sandy Hook Elementary School on Dec. 14 found his bed neatly made. An armoire held five matching tan-colored shirts with five pairs of khaki pants. Black garbage bags sealed with duct tape covered the bedroom windows.

The paper, which obtained the information via law enforcement sources, reports that a nearly empty cereal bowl was found near damaged computer parts that had apparently been smashed with a barbell.

During the shooting, a school secretary and nurse remained hidden in a closet in the office of the school principal, Dawn Hochsprung, unaware that police were using the office as a command center, the Courant reported.

The paper also explained that the FBI is continuing to use "sophisticated sound technology" to analyze Lanza's movements that morning.

Sources said the secretary in the main office did not hang up the phone after calling 911 and federal authorities are trying to use the sounds recorded through that open landline to help chart Lanza's movements in hopes of better understanding his actions.

Other revelations include the way in which Lanza parked his car at the school on the morning of the shooting. A source told the Courant that Lanza "parked his car in a way that could have set him up to ambush responding police officers."

Investigators also learned by interviewing surviving children that some of the first-graders in Victoria Soto's classroom were holding hands during the attack and were outside of Lanza's "initial line of fire." After Lanza's gun jammed, six of the children ran to safety.

Earlier this month, residents of Newtown voted to demolish Sandy Hook Elementary School and build a new school. Crews hired to demolish the building were required to sign confidentiality agreements that would bar them from photographing the site.
