Trayvon Martin's girlfriend, who was on the phone with him before the unarmed teen was shot and killed by George Zimmerman, will testify before a grand jury.
The grand jury will be impaneled April 10 to determine if Zimmerman, the neighborhood watch captain, should be charged with murder, according to reports.
The Trayvon Martin case gained national attention after he was gunned down by Zimmerman, who felt he was acting suspiciously in his gated community.
Martin was unarmed, and even though a 911 dispatcher told Zimmerman not to pursue Martin, he subsequently shot the teenager, claiming self defense.
To the outrage of many, local law enforcement in Sanford, Fla., declared that there wasn't enough evidence to charge Zimmerman with a crime in the February killing.
Amid public outcry, the Florida State Attorney's Office has since announced that a grand jury would ultimately decide if he should face criminal charges, however.
The FBI and the U.S. Justice Department have also launched investigations.
The 17-year-old Martin was on the phone with his girlfriend, whose name has not been released because she's a minor, as Zimmerman began to follow him.Sanford Police never questioned Trayvon's girlfriend, even though her parents contacted the cops to tell them she wanted to come in for a full interview.
A grand jury will now give her that chance to tell her side of the story.
"Trayvon's girlfriend has been told that the (Fla.) State Attorney's Office has prepared a subpoena for her to appear in front of the grand jury," a police source said.
Sanford Police Chief Bill Lee Jr. temporarily stepped down from his position Thursday, after he came under fire for not arresting Zimmerman in the case.
Zimmerman called 911 46 times in 2011, according to records. Not a single one of those calls resulted in an arrest or further action being needed by police.
