Witness: George Zimmerman Told Me Trayvon Martin Grabbed His Gun

Mark Osterman wrote a book defending Zimmerman

George Zimmerman's best friend and the author of a book defending him said the neighborhood watch volunteer told him Trayvon Martin went for his gun as the two grappled in a gated community in Florida last year.

Mark Osterman took the stand in Zimmerman's second degree murder trial and told jurors what Zimmerman recounted to him when he picked him up from the Sanford Police station after the Feb. 26, 2012 incident.
