That’s a statement to the DA by DeeDee. There never has been a grand jury. If the DA were really really incompetent it could be something the DA saw in the media or got third hand from the Martin’s attorney. That’s not likely.
Attorneys for Martin’s family said it wasn’t until weeks later, when Tracy Martin, Trayvon’s father, was looking through the teen’s cell phone bill that he noticed the timing of the last call. The family and their attorneys then contacted Trayvon’s girlfriend and heard her account of the night. Lawyer Benjamin Crump, who represents the family, recorded an interview with the girl and provided it with Martin’s cell phone records to federal authorities, who by then had joined the investigation.
