Nearly one year after the horrific shootings at Sandy Hook Elementary School that claimed 26 innocent lives, officials are still no closer to pinpointing a motive. There are, however, new details that have been released that include what shooter Adam Lanza did on the days leading up to the shooting.

Police say that Lanza’s mother, Nancy, left for a 3-day trip that week and had just returned home to sleep in her own bed when Lanza shot her dead. They found the rifle used to shoot her in her room. Details from a GPS system on Lanza’s car showed that he took a trip to the elementary school the day before the shootings, although why is still a mystery.

The next day, on December 14th, Adam Lanza drove to Sandy Hook armed with several weapons and rounds of ammo, burst in, and shot 20 children and six adults within five minutes before shooting himself. The tragedy immediately made headlines around the nation and a public plea began to President Obama for tighter gun control measures, even as the debate raged on among social media users.

Now, a 48-page report on the investigation that includes details about that day has been released, and the family members of the victims were notified of its release days in advance, though they say that no report will ever answer everything they need to know. The pages were taken from some 2,000; much of it was redacted due to Connecticut Legislature fighting to prevent its release, as it also did with 911 calls made from the school that day. A judge has said he will listen to the tapes and decide if they should be made public.
