VIDEO-Hacktivist targets Marathon bombing conspiracy theorists - Boston News, Weather, Sports | FOX 25 | MyFoxBoston

BOSTON ( -- A self-described hacktivist is pushing to stop a web-based movement claiming the Boston Marathon bombings were a government conspiracy.

The person known only as "Jester" communicated with FOX 25's Ted Daniel via a secure private chat service Wednesday. Jester says over the last few weeks, he's been targeting people he believes are trying to capitalize on the Marathon tragedy.

Jester has published the name, phone number, and address of the person he blames for a doctored image of bombing victim Martin Richard that made the rounds on Twitter.

The computer vigilante also launched a denial of service attacks on websites belonging to people associated with movements that claim the bombings are a government conspiracy. One of those sites has still not recovered.

"Since the Boston bombing, I have seen some really offensive stuff happening online," says Jester.

As for the right to free speech, the self-described professional pitier of fools says, "I would describe my actions as necessary. Some say I am against Freedom of Speech, but this is not the case. I fully support Freedom of Speech. The First Amendment protects us against government infringing on our speech rights, it doesn't apply to citizens."

Three people, including 8-year-old Martin Richard, were killed and over 260 others were injured in the April 15 bombings near the finish line of the Boston Marathon. One suspect in the bombings, 26-year-old Tamerlan Tsarnaev died days later following a shoot out with police and after being hit by a car reportedly driven by his teenage brother. The men are also accused of fatally shooting MIT officer Sean Collier.

Dzhokhar Tsarnaev remains in custody at FMC Devens. A social media movement calling for Tsarnaev's release was created shortly after his April 19 arrest.
