This allegation even received a blessing from Donald Trump Jr., who recently liked a tweet that proclaimed this conspiracy.
Baseless claims are being made, including that surviving students are actors.
That aide has since been fired, and the school's superintendent stepped up to verify the identity of the two students, Emma Gonzales and David Hogg, who have become vocal representatives of the movement.
With absolutely no proof, they are insinuating that blame for the shooting is on an Federal Bureau of Investigation agent father of a survivor.
Those are just some of the videos on YouTube now sowing disinformation about last week's mass murder at Marjory Stoneman Douglas High School in Parkland, Florida. As "evidence" for this theory, some people were posting footage of an unrelated news program Hogg apparently appeared on in California previous year.
The crisis actor conspiracy gained traction on Facebook this week.
"Unlike the people who are tweeting that stuff about me and my dad, I haven't lost hope in America and my dad hasn't either", said Hogg with his father by his side.
The conspiracies seemed to spill into the ranks of government, too.
Benjamin Kelly, district secretary for Rep. Shawn Harrison, emailed a reporter for the Tampa Bay Times that several students who appeared on television criticizing lawmakers on gun-control laws actually travel to different incidents when they happen.

The gun is the ballistic missiles that the Iranians are developing, unchecked by the nuclear deal and undeterred by UN Security Council resolutions, he said.
Kelly was sacked later that day.
Calls by student David Hogg for stricter gun laws in the days after last week's massacre have made him the subject of smear campaigns and demonstrably false conspiracy theories.
"Claiming some of the students on TV after Parkland are actors is the work of a disgusting group of idiots with no sense of decency", Rubio wrote.
The Florida high school student was asked about the conspiracies during a Tuesday night interview with CNN's Anderson Cooper, where he said the claims about him were "absolutely disturbing".
The president's son, Donald Trump Jr., highlighted the Gateway Pundit story and one by another far-right outlet, True Pundit, on his own Twitter account. His boss, Harrison, said on Twitter that he was "appalled" by Kelly's remarks.
"The fact that these people are being critical of me as a witness and personally as a victim.it's unbelievable", Hogg said before arguing that students at his high school showed more maturity than some elected officials.
That's what you would expect after being the most interviewed teen following the Parkland, Florida shooting at Marjory Stoneman Douglas Highschool on February 14, 2017.
He added, "I'm not acting on anybody's behalf".
