(CNN) – Items taken from Trayvon Martin’s cell phone — including a text-message discussion of drug use and pictures of a gun and marijuana plants — are among new details released Thursday by attorneys for the neighborhood watch volunteer accused of killing him without provocation 14 months ago.

The evidence, George Zimmerman’s attorneys say, paints a different picture of the 17-year-old than the one portrayed by his family and supporters. Lead defense attorney Mark O’Mara says he will try to use the evidence if prosecutors attempt to attack Zimmerman’s character during his trial on second-degree murder charges, set to begin next month.

Also Thursday, O’Mara filed motions in court. One asks for sanctions against the state for withholding evidence and for saying it didn’t have more evidence when asked. The second requests that his client’s trial be delayed.
