Boston Marathon bombing survivor waves fake leg at Dzhokhar Tsarnaev supporters outside courthouse

A Boston Marathon bombing survivor who lost a leg in the attack waved his prosthetic limb at a small group of Dzhokhar Tsarnaev sympathizers Thursday.

Marc Fucarile, walking with a cane, saw the protesters on his way to a Boston federal courthouse Thursday for Tsarnaev’s first public appearance in over a year.

The women say that Tsarnaev was set up and that authorities fabricated evidence concerning the bombing that killed three and injured more than 260 on April 15, 2013. One even described the government’s case against the suspected terrorist as “trickery,” according to WCVB.

“That’s trickery?” Fucarile countered, lifting the prosthetic limb that replaced his right leg.

“We’re talking about the prosecution,” Karin Friedemann said. “You should care that they get the right guy.”

Fucarile, who has been to most of the hearings related to the case, asked if Friedemann had even been inside to see the incriminating evidence. Then he entered the courthouse, while she stayed outside with her sign.

Inside, U.S. District Judge George O'Toole asked Tsarnaev, now 21, a series of questions to see if he was satisfied with his defense attorneys.

This could help refute possible post-trial claims that he was not afforded a fair trial.

The trial, expected to run three months, is scheduled to start in January.

The defendant is accused of having set off two homemade bombs at the race's finish line and fatally shooting a police officer three days later.

Friedemann told the local ABC affiliate that she wants people to “realize the possibility of innocence.”

Valerie Vanetta, another protester, said, “We're here to raise awareness about things concerning the case that people may not be aware of."

When asked about the Tsarnaev supporters after the hearing, Fucarile said, “They’re all welcome to their opinions. Like I said, there are supporters for him and there are supporters for us.”

Fucarile expressed gratitude for all the help he has received since the attack — thanking the FBI, the Boston Police Department and the first responders.
