While supporters across the country have helped hurl the Trayvon Martin case to the national stage, grieving family members say they need more financial help to make sure that justice is served.

Since their unarmed 17-year-old son was shot and killed by neighborhood watchman George Zimmerman in Sanford, Fla., the Martins have been fighting the self-defense law that's keeping Zimmerman out of jail. The grieving family has had some successes in bringing attention to the Stand Your Ground law, but is hoping that a fundraising campaign will help push their efforts even further.
