Newtown gunman Adam Lanza reportedly made a chilling 2m-long "scoresheet" tallying body counts, names and weapons used in previous mass murders before he shot dead 20 children and six adults at Sandy Hook Elementary School last year.
Investigators reportedly believe the 20-year-old video gamer was hoping get the top score on the spreadsheet when he went on a shooting rampage at the school in Connecticut after killing his mother, Nancy Lanza, on December 14.
An anonymous law enforcement veteran told the New York Daily News that police believed Lanza targeted an elementary school because that was where he could rack up the greatest number of kills.
"They believe that he picked an elementary school because he felt it was a point of least resistance, where he could rack up the greatest number of kills," the source said.
"This was the work of a video gamer, and that it was his intent to put his own name at the very top of that list."
The source learned about the spreadsheet when Connecticut State Police colonel Danny Stebbins spoke at the International Association of Police Chiefs and Colonels mid-year meeting in New Orleans last week.
"We were told (Lanza) had around 500 people on this sheet – names and the number of people killed and the weapons that were used, even the precise make and model of the weapons," the source said.
"It sounded like a doctoral thesis, that was the quality of the research."
Lanza shot himself dead as police arrived at the scene of the shooting, which was the second deadliest in American history after the 2007 Virginia Tech massacre.
