(CBS/AP) SANFORD, Fla. - After listening to recordings of 911 calls Friday night, the family of a black teenager fatally shot by a white neighborhood watch volunteer say they're convinced now more than ever that the shooter should be charged.

Attorney Benjamin Crump, who is representing the family, told reporters that 17-year-old Trayvon Martin's parents both broke down and cried as they listened to the 911 recordings.

"They are completely devastated, are they are in unbelievable grief," Crump said.

Police agreed to release the recordings on Friday. Martin's parents previously sued to have the recordings released. A hearing for the case was scheduled for Monday.

Officials released a total of seven 911 calls. All of the callers described a single shot.

"There is somebody screaming outside," one female caller said, as an unknown male voice can be heard crying in the background. Then a shot is heard.

A male caller described a physical altercation between Martin and the shooter.

"I just heard a shot right behind my house," the caller said. "They're wrestling right behind my porch. The guy is yelling 'Help.' I'm not going outside."

Martin was carrying a drink and candy when George Zimmerman, the neighborhood watch captain, called 911 to report a suspicious man, authorities said.

CNN reports the 911 dispatcher told Zimmerman not to confront the man, but by the time police arrived, Martin lay dead with a gunshot wound in the chest, according to Sanford Police Chief Bill Lee.

"Hurry please ... there's someone screaming outside," a neighbor whispers on another 911 recording. "There's a gunshot, hurry up ... there's someone screaming. I just heard a gunshot."

In another call, a woman begs the dispatchers to send help, saying someone is "screaming and hollering" for help.

Martin's parents, Tracy Martin and Sybrina Fulton, accused Sanford police of botching the investigation and criticized them for not arresting Zimmerman, who says he shot Martin in self-defense. Martin was not armed and his parents say the police department hasn't arrested Zimmerman because he is white and their son was black.
