Trio of witnesses take stand in George Zimmerman trial
A trio of witnesses took the stand in Day 4 of the George Zimmerman trial, all hearing something on the night Trayvon Martin was fatally shot.
With just two weeks remaining before his trial, George Zimmerman returns to court Tuesday for what may be his last pretrial hearing, a session that could turn into a marathon with his attorneys asking for a trial delay and asking that an especially damaging state audio expert be banned from testifying.
