The family of a teen shot over Orlando's NBA All-Star Weekend is outraged that the man who pulled the trigger has not been arrested.

The 17-year-old was killed, and his family said they have gotten no help from police in Sanford, where he was visiting family members.

Trayvon Martin went to a nearby store, when his family said he got into an altercation with George Zimmerman, the captain of the neighborhood watch program at the Retreat at Twin Lakes gated community.

Family members said Zimmerman shot the teen for no reason, and they want answers, including why the neighborhood watch captain was carrying a gun in the community, and why he hasn't been arrested for murder.

"My son left Sanford, Florida, in a body bag, while George Zimmerman went to sleep in his own bed," said Tracy Martin, Trayvon's father.

"We are here on behalf of this family to demand the arrest of George Zimmerman in the name of justice, that police arrest him for shooting in cold blood Trayvon Martin, killing him," said attorney Ben Crump, who is representing the teen's family.

The family said Zimmerman admitted to shooting the teen, whom they said was no threat. When the teen was found, he had only a drink and a bag of Skittles in his pocket.
