911 tapes out in killing of unarmed black teen

(CBS News) Police in Sanford, Fla. have released recordings of 911 calls surrounding the shooting death of unarmed black teenager last month.

Trayvon Martin, 17, was gunned down by a white neighborhood watch volunteer on Feb. 28.

George Zimmerman admits shooting him, but has not been arrested. Martin's family and their supporters are furious.

They've demanded to hear 911 tapes related to the shooting, and Friday night, under pressure, Sanford police released them.

The unarmed teenager was walking inside a subdivision where relatives lived. Zimmerman called police about a suspicious person.

Zimmerman: This guy looks like he's up to no good. He's got his hand in his waistband. ... Something's wrong with him."

Dispatcher: "Are you following him?"

Zimmerman: "Yes."

Dispatcher: "OK. We don't need you to do that."

Zimmerman followed Martin anyway. They fought. Zimmerman shot him once in the chest.

Dispatcher: "So you think he's yelling 'Help?"'

Caller 1: "Yes."

Dispatcher: "Alright. What is your...

Caller 1: "Just... (pause, gunshot heard) There's gunshots."

Caller 2 (distraught): "They just said he shot him dead. The person is dead, laying on the ground."

Local police said they released the recordings to calm community concerns about Martin's killing.

Defense attorney Lauren Lake, who was visibly angry, told "CBS This Morning" co-host Rebecca Jarvis bias and racial profiling may very well have been involved in this case. To see the interview, click on the video below.

An emotional Sabrina Fulton, Trayvon's mother, told reporters, "I'm hoping that one day, one day, he's gonna walk through the door, and this is gonna be a nightmare."

What is it Trayvon's father, Tracy Martin wants?

"Justice. ... I want justice to be served. This guy should be locked up."

That's justice to you?

"That's justice," Martin responded.

Local prosecutors promise "a thorough, deliberate and just review" of the case, but would set no date for deciding whether to pursue criminal charges.
