A girl who overheard part of an incident involving Florida teenager Trayvon Martin can help prove he was killed "in cold blood," an attorney for Martin's family said Tuesday.
The girl, who was dating the 17-year-old, "completely blows (George) Zimmerman's absurd self-defense claim out of the water," Benjamin Crump said at a news conference.
He said the girl -- who does not wish to be identified -- "connects the dots" to describe what happened that day when she lays out what she overheard while on the phone with him.
