They're not stopping until they feel justice has been served.

More rallies on behalf of 17-year-old Trayvon Martin, who was shot by neighborhood watch volunteer, George Zimmerman, in a Sanford Florida community one month ago. As Trayvon's parents continue to mourn their loss in Sanford, nationwide hostility towards George Zimmerman continues to grow.

The New Black Panther Party has offered a $10,000 bounty for his capture.

All we know is he's still in hiding, but has told investigators Martin attacked him, and slammed his head to the ground, before the shooting.

Here at home, Texas Southern University students organized a "Rally for Justice." Students from area schools, colleges and community organizations wore hoodies and yellow ribbons to show support.
