Just adding to this:
"On March 20th Benjamin Crump held a major press conference where he revealed that he was in possession of a sworn affidavit from Trayvons 15-year-old girlfriend <modsnip>.
We took another step in this what has been a daily journey for the past three and a half weeks.
Mr. Martin, on Sunday evening [March 18th], was working with his cell phone account, trying to figure out Trayvons password. And he looked on it, and he saw who the last person was that Trayvon Martin talked to while he was alive.
He called me late Sunday night and told me that he had called the young lady, and he told me, and I was just utterly shocked when he told me the time that they talked. They had talked all that day, about 400 minutes, starting that morning to the afternoon. Like many teenagers do, they talked on the phones."
