SANFORD, Fla. — The parents of a slain Florida teenager are blaming police for leaking information about their son being suspended for marijuana and details about the fight he had with the shooter that portrayed the teen as the aggressor.

Trayvon Martin’s mother, Sybrina Fulton, and family attorneys said Monday that it was part of an effort to demonize her 17-year-old son who was shot and killed last month by neighborhood watch volunteer George Zimmerman.

“They killed my son and now they’re trying to kill his reputation,” Fulton told reporters.

Martin was suspended by Miami-Dade County schools because traces of marijuana were found in a plastic baggie in his book bag, family spokesman Ryan Julison said.

Martin was serving the suspension when he was shot Feb. 26.

The Sanford Police Department insisted there was no authorized release of the new information, but acknowledged there may have been a leak. City Manager Norton Bonaparte Jr. said it would be investigated and the person responsible could be fired.
