On Friday morning, Adam Lanza, 20, got into his car and left the house he shared with his mother, Nancy Lanza, who’s lifeless body was now hidden within after Adam had shot her dead.
Lanza entered the school shortly before 9:30 a.m. dressed entirely in black and carrying two automatic handguns
At 9:30, classes began at Shady Hook. It was the same school where Nancy Lanza taught kindegaten .
Surrounded by woods, the building appeared to be an idyllic small town school.
He was armed with one rifle, a Bushmaster .223 Remington with more than 30 rounds, and two pistols, a Sig Sauer P226 9mm handgun with 15 rounds and a Glock 9 mm with 17 rounds.
Shortly after entering the school, Lanza opened fire.
He shoot the principle, five other adults, and twenty children in just two rooms of the elementary school.
Witnesses later described the scene as nightmarish.
Children described hearing loud booms as the gunman let out as many as 100 rounds and as their teachers ushered them into corners away from his killing spree.
Five minutes after the start of classes, the first 911 call goes out.
Ten minutes after Lanza began shooting, police arrive at the school in response to a 911 call.
They began evacuating students and teachers to a fire station a little less than half a mile away.
Images later showed the traumatized, crying students hand-in-hand as they left the buildings.
By 9:45 p.m. the SWAT team had begun to sweep the premises.
Upon investigating the school further they find Lanza has taken his own life.
Approximately half an hour after Lanza opened fire, President Barack Obama is briefed on the tragedy.
A short while later police investigating Lanza discover his mother’s body.
As police find Lanza’s mother, the shooter’s brother, Ryan Lanza, discovered what his brother has done through a news report on CNN that misidentifies Ryan as the killer.
Just after noon, Ryan Lanza left his accounting office in Times Square and heads home to Hoboken, N.J.
Police met him there. He gave himself up and was taken into custody for questioning.
