I don’t want to impugn her honesty, but you could infer from the news (I know, very unreliable in this case) that Benjamin Crump, the Martin family lawyer, spent hours with that girl before law enforcement ever interviewed her. Zimmerman’s lawyers are unlikely to have talked to her at all at this point.
Which would of course be a failure on the part of law enforcement. From news reports, (reliability issue again), the police did not use Trayvon Martin’s cell phone to identify him early on, and did not check his calling history during the time in question.
Some time ago, ABC published an article about the girlfriend and the phone calls. It had a photo of the T-Mobile bill for Martin's phone:
We see the two calls he received just before the fight. Then there is a gap until March 2, at which time someone used his phone to call 911.
Hmmm. Could that be when the Sanford PD finally got around to investigating the phone? Could the 911 call be the Sanford PD calling themselves in order to find out the phone's number?
It may be that the phone was passworded. Passworded phones can usually be used to call 911 without needing to know the password, I believe. If the phone was passworded, the police would have needed T-Mobile's assistance for any investigation other than discovering the number by calling themselves.
I think I read that Martin was carrying no ID. So, his phone would have been the quickest way to identify him, I would think. Why did it take until March 2?
