A Florida professor was fired this week after initiating a years-long campaign claiming the Sandy Hook massacre was a hoax and harassing the family of a victim he believes never existed.

James Tracy, who teaches Culture of Conspiracy at Florida Atlantic University, launched his own conspiracy theory in the aftermath of Sandy Hook three years ago, based on conflicting media reports from the day of shooting that lead him to question whether it happened at all.

As part of the bizarre theory, Tracy allegedly began harassing the parents of six-year-old Noah Pozner - one of 20 children in the attack by shooter Adam Lanza - demanding proof that the child ever existed.

Tracy was finally sent a termination letter from the university this week, which he has 10 days to respond to, according to The New York Daily News.

The termination appears to have been spurred by an op-ed written by the victim's parents, Lenny and Veronique Pozner, that was published in the Sun Sentinel last week, explaining the harassment they had allegedly been hit with from Tracy.

The university has previously said Tracy does not speak for the school.

'In fact, Tracy is among those who have personally sought to cause our family pain and anguish by publicly demonizing our attempts to keep cherished photos of our slain son from falling into the hands of conspiracy theorists,' the couple wrote in the piece.

'Tracy even sent us a certified letter demanding proof that Noah once lived, that we were his parents, and that we were the rightful owner of his photographic image.'

Many have called for Tracy to be fired over the years due to his theories, particularly officials in Newtown, Connecticut, where the shooting took place.

Tracy suggested on his blog - memoryholeblog.com - the massacre did not unfold in the way authorities said it did, and may not have happened at all.

'While it sounds like an outrageous claim, one is left to inquire whether the Sandy Hook shooting ever took place - at least in the way law enforcement authorities and the nation’s news media have described,' Tracy wrote.

Tracy insinuated 'corporate media' institutions, as well as government authorities, spun official accounts of the massacre that left 26 dead, including 20 children, to drive a preconceived agenda of gun control in America.

'As documents relating to the Sandy Hook shooting continue to be assessed and interpreted by independent researchers there is a growing awareness that the media coverage of the massacre of 26 children and adults was intended primarily for public consumption to further larger political ends,' he wrote on his blog.

Tracy has seemingly based his allegations largely on the flurry of conflicting media reports released during the hectic day.

'I describe myself as a scholar and public intellectual interested in going more deeply into controversial public events,' he has previously said.

'Although some may see (my theories) as beyond the pale, I am doing what we should be doing as academics.

'I think that the entire country mourned about Sandy Hook and yet, once again, the investigation that journalistic institutions should have actually carried out never took place as far as I'm concerned.'

A total of 26 people were killed in the Sandy Hook massacre on December 14, 2012, with 20 children and six staff shot dead by Lanza.

Prior to driving to the school, Lanza shot and killed his mother at their Newtown home.

Lanza killed himself inside the school as first responders arrived.

As with many conspiracy theorists who find darker linings in even the most horrific tragedies, this is far from his first foray into the world of the unproven.

Mr Tracy has written a number of book chapters about media coverage of wars, economic overhauls and union negotiations.
