George Zimmerman's defense attorneys on Thursday released photos and text messages from 17-year-old Trayvon Martin's cellphone ahead of a hearing that will determine whether they can be used at Zimmerman's murder trial.

Zimmerman is charged with fatally shooting Martin last year during a confrontation at a gated community in Sanford. He is pleading not guilty, claiming self-defense. His trial starts next month.

The photos show Martin blowing smoke and extending his middle finger to the camera. The photos also show a gun and what appears to be a potted marijuana plant.

In the text messages, Martin tells a friend that his mother has told him he needs to move out of her house and move in with his father since he was caught skipping school.

Prosecutors have filed a motion asking Circuit Judge Debra Nelson to prevent the photos, texts and other personal information from being used at the second-degree murder trial.  The hearing is set for next Tuesday.

Zimmerman's defense attorney, Mark O'Mara told The Associated Press last week that the materials could be relevant if prosecutors put a spotlight on Martin and his character.

"If the state puts at issue Trayvon, who he was. If the state makes that an issue, we get to respond to that," O'Mara said.
