Sandy Hook: The Minutes That Changed Newtown

At 9:35:39 on the morning of December 14, 2012, Newtown police received the first 911 call from Sandy Hook Elementary School. An officer would arrive in fewer than four minutes. By then, the attack was almost over. To understand what happened inside those minutes, we need to begin somewhere else: at a home in Newtown, and with the twenty-year-old who lived there with his mother.

Adam Lanza had struggled for years. A 2014 review by Connecticut’s Office of the Child Advocate described developmental difficulties beginning in early childhood, followed by severe anxiety that disrupted his schooling. In eighth grade, he was placed on homebound status. At fourteen, specialists at the Yale Child Study Center recommended extensive educational and therapeutic support. According to the review, much of that advice went unheeded, and Lanza and his parents did not appear to participate in mental-health treatment after 2008. The reviewers also documented his growing preoccupation with mass murder and his increasing isolation. These findings matter as background, not as a diagnosis of why he killed. The child advocate’s authors stressed that Lanza alone was responsible for his actions.

In the months before the shooting, his mother reported that he rarely left the house and seemed despondent. The child advocate’s review said it was unclear whether anything was done to restrict his access to guns. Investigators later established that the firearms recovered from the two crime scenes had been legally purchased by his mother. Connecticut’s state’s attorney would find evidence that Lanza planned the attacks and his own death. But investigators found no clear explanation for his choice of the school. What they could reconstruct was the sequence of his actions that morning.

The first killing took place at the house on Yogananda Street. Lanza shot and killed his mother, Nancy, in her bed with a rifle. He then went to Sandy Hook Elementary School carrying other weapons. The school building was locked. He did not gain entry by being let in: he shot his way inside with a Bushmaster rifle. The noise brought school employees toward the north hallway. There, he killed the principal and the school psychologist and wounded two other staff members.

Lanza entered the main office. Staff were hiding there; according to the state’s attorney’s report, he apparently did not see them. He returned to the hallway and went into two first-grade classrooms, numbered 8 and 10. Investigators could establish what happened in each room, but not which room he entered first. In classroom 8, he killed fifteen children and two adults. In classroom 10, he killed five children and two adults. The state’s attorney reported that all of those killings were carried out with the Bushmaster rifle. That is the documented sequence; assigning an order to the two classrooms would make the account sound more certain than the evidence allows.

As the first emergency call came in, police were being dispatched into a situation they could not yet see. The first officer reached the school less than four minutes after that call. About a minute after the officer arrived, Lanza shot himself in classroom 10 with a pistol. The first officer entered the building fewer than six minutes after arriving on school property. Police had not caught the killer alive, and their arrival had not ended the attack: he had taken his own life before they got inside. From the first call to his death was fewer than five minutes. At the school, twenty first-grade children and six adults were dead; two other adults had been wounded. Counting Nancy Lanza at the house, the number of people murdered was twenty-seven.

There was still an urgent question for the officers clearing the building: was anyone else involved? During the response, police encountered a man outside the school. People found in the surrounding wooded areas were initially treated as possible suspects while officers worked out who they were. Responders continued clearing the school and evacuating staff and children under the possibility that there was more than one attacker. Investigators later examined those encounters and found no additional shooter.

The investigation did not rest solely on accounts from inside the school. Investigators examined the weapons, cartridge cases, evidence from the house and the school, and potential leads about accomplices. Tests linked the school’s examined rifle cartridge cases to the rifle found in the classroom with Lanza’s body. Investigators also identified the pistol used in his death and linked the rifle found at the house to the bullets recovered from his mother. DNA testing revealed no potential accessory or co-conspirator. In his November 2013 report, the Danbury state’s attorney concluded that Lanza had acted alone. Because he was dead, and because investigators found no probable cause to charge anyone else, there would be no state prosecution. The investigation was closed, subject to reopening if reliable new evidence emerged.

That finding answered who carried out the killings. It did not answer every question a family—or a town—could ask. The state’s attorney said investigators found no clear reason why Lanza chose Sandy Hook Elementary School. The child advocate’s later review examined missed opportunities to support him and failures of communication among adults and institutions. It did not say those failures made the massacre inevitable, or that mental illness itself explains such violence. Background can help us examine warning signs and decisions without turning them into an excuse or a certain prediction.

The final record holds two truths together. The attack unfolded with devastating speed, and the evidence identified the person responsible. Yet no trial followed, and the investigation could not establish a conclusive motive. Remembering Sandy Hook means not smoothing over those limits. It also means keeping the people killed—Nancy Lanza, six school adults, and twenty children—at the center of the story, rather than allowing its unanswered question to eclipse them.
