An exhaustive ENQUIRER investigation has uncovered chilling new revelations about the crazed Connecticut school shooter!

In a world exclusive interview, the man who built the home where killer Adam Lanza lived recalls reveals details about the basement bunker where the deranged 20-year-old plotted his bloody massacre at Sandy Hook Elementary School.

Contractor Robert J. Riebe recalls meeting young Adam when he sold the property in Newtown, Conn., to the Lanza family.

Little did he realize back then that the child would someday slaughter 26 people, including 20 first-graders, before committing suicide in a criminal act that stunned America.

“It gives me chills when I think that I shook his hand,” Riebe told The ENQUIRER. “I couldn’t believe it when I heard the news. I was shocked.”

Riebe built the four-bedroom, three-bath two-story home and sold it to Lanza’s parents, Nancy and Peter, in July 1998.

"The basement could easily be a place where someone could spend long hours,” Riebe, 49, told The ENQUIRER.

Riebe also talks about Adam’s mother, Nancy, and her obsession with guns.

The mass murder of innocents has riveted the nation as The ENQUIRER continues its special investigation that no other publication can match. FOR THE FULL STORY - it’s ONLY in the NEW ENQUIRER – ON SALE NOW!
