The anniversary comes days after a judge blocked the sale of Alex Jones’ Infowars platform to The Onion, a satirical news outlet. The forced sale came after Jones was ordered to pay nearly $1.5 billion to Sandy Hook families in a defamation case for calling the shooting a hoax.

Scripps News spoke with Robbie Parker, who lost his 6-year-old daughter Emilie in the shooting and testified at Jones’ damages trial. Parker is the author of the new book, “A Father’s Fight: Taking on Alex Jones and Reclaiming the Truth about Sandy Hook.”

The blocked sale was "Obviously a lot of disappointment, Parker told Scripps News, but “We know that we’re on good legal standing with everything that happened, and [the judge] agreed that we were, and there wasn’t anything wrong that happened in the sale. So it’s just a setback, really. Jones can try and claim victory here, but at the end of the day his Infowars business is still going to be sold.”
