In a broadcast past year called "Sandy Hook Vampires Exposed", Jones suggested a CNN interview with De La Rosa was faked - a claim that her lawsuit blasts as a "sick lie". As HuffPost reported, Alex Jones has repeatedly claimed that this travesty was a hoax.
The lawsuits allege that Jones constantly calling the parents "crisis actors" and insisting the shooting was a false flag operation has defamed them and led to victims' families receiving death threats.
The other suit was filed by Leonard Pozner and his ex-wife Veronique De La Rosa who also their six-year-old son Noah in the shooting.
Both lawsuits are seeking more than $1 million in damages from Jones and his Internet news show Infowars.
In a 2017 interview with Megyn Kelly, Heslin spoke of holding his dead son "with a bullet hole through his head".

Aid was received from Florence County EMS, Kershaw County EMS, Darlington County EMS, Lexington County EMS and Hartsville Rescue. A sign in front of the Lee Correctional Institution in Bishopville, South Carolina , is seen in this image from Google Maps.
Soon after the segment, Infowars reporter Owen Shroyer told viewers that the father's claim wasn't possible because the coroner identified victims through photos and not in person.
Jesse and Noah were among the 20 first-grade students gunned down inside the school in CT on December 14, 2012. The children's bodies were eventually turned over to their parents for their funerals, the lawsuit said. Kelly had asked Heslin what he thought of the conspiracy theorist's previous claims that the shooting was a "giant hoax".
The second lawsuit by, Pozner and De La Rosa, who were married at the time of the shooting, focuses on an April 2017 broadcast on Infowars where Jones discussed an interview De La Rosa gave to CNN's Anderson Cooper shortly after the tragedy near Edmunds Town Hall in Newtown.
HuffPost reported that the attorney representing the parents suing Alex Jones, Mark Bankston, is involved in another suit against Jones. Jones didn't reply to a request for comment sent through his website.
Jones has pushed similar views about the February 14 shooting at Marjory Stoneman Douglas High School in Parkland, Florida, in which 17 people were killed, referring to the attack as a "false flag", or staged, operation.
