George Zimmerman case heads to federal grand jury

ORLANDO, Fla. – A federal grand jury is expected to hear testimony Wednesday surrounding the George Zimmerman case.

The hearing is related to whether Zimmerman violated Trayvon Martin's civil rights when he shot and killed the unarmed teen in Sanford in 2012.

At least one witness has been subpoenaed to testify. That man is believed to be Zimmerman's former neighbor, Frank Taaffe.

Taaffe stood by Zimmerman throughout his trial but recently said publicly that he believed Zimmerman racially profiled Martin.

The grand jury will meet at the Federal Courthouse in Orlando.

Zimmerman, 30, was acquitted last year of a second-degree murder charge in Martin's death.
