Video purportedly shot minutes after George Zimmerman shot Trayvon Martin to death shows heavy bleeding on his scalp, lending possible credence to his claims he killed the teen in self-defense.

ABC aired the exclusive video on "Good Morning America" Friday, hours before Zimmerman appeared before a judge who ruled he could be freed on bond while he awaits trial on a second degree murder charge.

Zimmerman told the 17-year-old boy's parents in court that he was "sorry for the loss of your son," but maintained he acted in self defense. His lawyer said he was confronted by the unarmed teen after calling police to report a suspicious person in his gated community. One witness has said he saw the pair fighting, and that Martin was on top of Zimmerman, slamming his head into the pavement.

The racially-charged case has shone a spotlight on Florida's "Stand Your Ground" law, which holds that victims do not have a duty to retreat when under attack, and may instead meet the attack with sometimes deadly force.
