Students rally, demand arrest in Trayvon Martin case

Neighborhood watch leader George Zimmerman admitted to fatal shooting

SANFORD, Fla. - Florida college students angered by the shooting death of teenager Trayvon Martin are protesting Monday outside the Seminole County criminal courts building.

The rally was organized by Florida members of the Black Law Students Association. 

The Seminole County building houses the state attorney's office, where the case is being reviewed to decide if criminal charges will be filed against George Zimmerman, the neighborhood watch volunteer who killed the 17-year-old.

Zimmerman, 28, has not been arrested, causing public outrage. Neighbors said Zimmerman has since moved out of the complex.

Sanford police say they cannot arrest Zimmerman because he said it was self-defense, a claim supported, they say, by witness accounts and other evidence, including Zimmerman's bloody nose.

The 911 calls made in the February shooting were released Friday, shedding more light into what happened in the shooting. Zimmerman didn't elaborate in the calls what made Martin look suspicious.

Sanford police said Zimmerman has called 911 46 times since 2001, reporting disturbances, break-ins and other incidents. On nine different occasions, Zimmerman has reported a suspicious person.

From January 2011 to February 2012 records show there were 402 calls to police from that neighborhood, five were about burglaries, but a majority of the calls were about disturbances.

Local 6 has obtained the 911 calls Zimmerman had previously made before the shooting. Check back for more information on the calls.

Sharpton to hold rally

Meanwhile, the Rev. Al Sharpton is planning a rally for Martin.

Sharpton will hold the rally Thursday at the First Shiloh Baptist Church in Sanford.

Martin's family has criticized police for not arresting Zimmerman.  Zimmerman had called police to report a suspicious person walking through the neighborhood.

The teen had gone to a convenience store and had a bag of Skittles and an iced tea when he was shot.  Martin's family says 911 calls show the teen was terrified as he tried to flee Zimmerman.

Zimmerman's father says his son has been unfairly portrayed as a racist.
