College Moves to Fire Professor Who Questioned Sandy Hook

Florida Atlantic University has taken steps to fire a professor who has repeatedly raised questions about the shooting deaths of children at Sandy Hook Elementary School in Connecticut and other mass killings.

FAU said in a release on its website that School of Communication and Multimedia Studies professor James Tracy was served a notice of termination Wednesday. The university said Tracy has 10 days to respond.

Although the school gave no reason for the action, the parents of one student killed at Sandy Hook recently claimed in a Florida newspaper opinion piece that Tracy was taunting them.

Tracy was reprimanded in 2013 for writing in his blog that the Sandy Hook killing was staged and has questioned accounts of other mass slayings.

Tracy did not respond to emails Thursday seeking comment.
