EXCLUSIVE: Trayvon Martin's family tells Soledad O'Brien of grief over losing their son, say they want justice

A heartbroken family is speaking out for the first time, outraged that the man who killed their son is still walking free.

Trayvon Martin, a 17-year-old from Florida, was shot dead on February 26th. He was walking home from a 7-11 near Orlando, through a gated community where his father's fiancee lives. Neighborhood Watch captain George Zimmerman admits he shot Trayvon, but claims it was in self defense. The family says it was racial profiling: an unarmed African-American boy shot by a larger, armed white man.

This morning on "Starting Point with Soledad O'Brien," Soledad talks with Trayvon's father Tracy Martin, his mother Sybrina Fulton and family attorney Benjamin Crump about the latest in the case. Tracy says no parent should have to bury his or her child, and all they want for Trayvon is justice.

In the last video, CNN senior legal analyst Jeffrey Toobin explains the legal complexities of the case.
