Were Trayvon Martin's civil rights violated the night George Zimmerman shot and killed him?
A federal grand jury is set to convene Wednesday in downtown Orlando to determine if there's enough evidence to indict Zimmerman for violating Trayvon Martin's civil rights.
Frank Taaffe, Zimmerman's former friend and neighbor, told News 13 he has been subpoenaed to testify in front of the grand jury at 1 p.m.
The grand jury was originally scheduled to convene Nov. 5, but according to Taaffe, it was rescheduled for a week later, Nov. 12.
At first, Taaffe was an outspoken supporter of Zimmerman before and during his trial, in which he was found not guilty of second-degree murder.
But nearly a year later, Taaffe had a change of heart, saying he now believes Zimmerman racially profiled Trayvon Martin.
Now, Taaffe has been called to testify before a federal grand jury.
News 13's legal expert, David Jancha from the NeJame Law Firm, said it's unlikely that Zimmerman will make an appearance in court Wednesday.
"Completely one-sided proceeding; it's the government and the government only that's providing evidence," said Jancha. "I don't believe George Zimmerman will be present. Not only does he have the Fifth Amendment right against self-incrimination, but usually it's not something that happens."
The FBI would only confirm that there was an ongoing investigation into the alleged civil rights violation.
