>> are until now photos from trayvon martin's family have mostly shown him as a much younger boy. digital pictures show pictures snapped closer to the 17-year-old's death, also on his cell phone , a marijuana plant, and a handgun, and hundreds of text messages including discussions of afterschool fights. the log does not show who is texting and who is responding. i lost da first but won da second and third. oh, so it was three rounds? damee well at least you won, lol but you need to stop fighting back for real. the defense says the text about fighting is important because 29-year-old george zimmerman who is accused of shooting the unarmed martin claims it was the teenager who turned on him and began to beat his head into the cement sidewalk when zimmerman fired the fatal shot.
>> it showed he had the propensity toward violence and acting in a similar way previously that he acted on george .
>> reporter: attorneys for martin's family say the photos are irrelevant and could pollute the jury pool. the family said they know unflattering material about their son could be part of the case.
>> you have george zimmerman who is alive. you have trayvon martin who is dead, who is not here to tell his story. of course he's going to blame the victim.
>> reporter: it will be up to the judge to determine if a jury will ever even see this evidence. kerry sanders , nbc news, miami.
