Lenny Pozner, the father of a child murdered in the 2012 shooting at an elementary school in Newtown, Connecticut, won a defamation lawsuit Monday against the publishers of a book who said the tragedy never occurred.

A Wisconsin judge ruled in favor of Pozner, whose 6-year-old son Noah was among the 26 people killed at Sandy Hook Elementary School in December 2012.

Publisher Moon Rock Books apologized to Pozner and stated it would pull Nobody Died at Sandy Hook, which was written by Mike Palacek and James Fetzer. 

Fetzer had previously alleged that “evidence clearly shows this wasn’t a massacre, it was a FEMA [Federal Emergency Management Agency] drill.”

Fetzer is one of many conspiracy theorists who claim Sandy Hook was a staged incident with “crisis actors” posing as the students and teachers to push for more gun control. Right-wing commentator Alex Jones of Infowars is one other such conspiracy theorists who has been mired in a lawsuit against many of the deceased children’s parents after first claiming in 2016 that the massacre was fabricated. The parents of the victims have received countless death threats and faced other types of harassment.

A trial to determine precise damages from Fetzer and Palacek against Pozner has been set for October.

In the latest development surrounding the legal battle between the shooting victims’ parents and Jones, child pornography electronic files were found this week among the court records Jones’ lawyers sent to the legal team for the Sandy Hook parents. Jones claimed these damaging documents are simply an attempt to set him up.
