EATONVILLE, Fla. (AP) -- African-American community churches around the nation are amplifying the cries for justice in the shooting death of 17-year-old Trayvon Martin.

Martin was shot while wearing a hooded sweatshirt as he walked home on a rainy night in a gated community. The neighborhood watch volunteer who shot him, 28-year-old George Zimmerman, is the son of a white father and Hispanic mother, and the demands to charge him in Martin's slaying have increased.

In religious centers from Florida to Atlanta, New York and Chicago, many preachers and their congregations wore hooded sweatshirts in Martin's memory. But while the call continued to be for the arrest of shooter George Zimmerman, there were also a large call to use the incident to spark a larger movement.
