A parent whose child died in the mass shooting at Sandy Hook Elementary has won a defamation suit against the authors of a book who claim the shooting never happened.

A Wisconsin judge ruled Monday that Lenny Pozner, the father of Noah Pozner, had been defamed by the authors of the book entitled "Nobody Died at Sandy Hook."

The decision is a victory for the relatives of victims in the shooting who are taking a stronger stand against conspiracy theorists.

The publishers of the book have reportedly apologized to Pozner and in a settlement have agreed to stop selling the book.

Noah was one of 20 first graders and six educators who were killed at Sandy Hook back in 2012.
