Gunfire and screaming can be heard in dramatic 911 calls released late Friday from the shooting of Trayvon Martin.
In one call, placed by the shooter George Zimmerman, he actively pursues the teen before the deadly shooting.
"Are you following him," an emergency dispatcher asks after Zimmerman describes Trayvon as a black male who was acting suspiciously.
Zimmerman responds: "Yeah."
"OK, you don't need to do that," the dispatcher says.
The recordings were released after Trayvon's family spent two hours with city officials, listening to the calls that documented the 17-year-old's last moments alive.
"What you hear on that tape is shocking. It's riveting," Benjamin Crump, an attorney for Trayvon's family, said after the group emerged from their meeting with officials late Friday.
Police had previously refused to release the calls. Zimmerman, a 28-year-old neighborhood crime watch volunteer, has not been arrested and is not charged with a crime. He claimed the Feb. 26 shooting was in self defense.
