Residents of a Sanford, Fla., community are demanding answers about why a Neighborhood Watch captain has still not been arrested following the shooting death of an unarmed teen last month, according to 9.

George Zimmerman, 28, hasn't been arrested for shooting and killing 17-year-old Trayvon Martin, officials said.

Martin was visiting family in this gated Sanford townhome community. 

Zimmerman called police around sunset on February 26 to report a suspicious black man in the predominately white neighborhood.

Sanford police Chief Bill Lee said that dispatchers told Zimmerman not to confront the teenager.

However, Zimmerman did and before police arrived, the two got into an argument and then a scuffle.

Zimmerman shot the teenager in the chest, police said.

He told police the shooting was in self-defense.

Zimmerman is nearly twice the teenager's size, measuring at 5 feet 9 and weighing 250 pounds, according to police records.

During the news conference, Lee said that Zimmerman's claim of self defense has not been proven or dis-proven. He also said that after the police department's investigation is complete, they will hand it over to the State Attorney's Office.
