O'Mara then asked where Fulton first heard the 911 call. She said she heard the call in the Sanford mayor's office.  When asked, Fulton said Tracy Martin, who is Trayvon Martin's father, along with Trayvon Martin's brother, Jahvaris Fulton, Stephanie Sands, Darian Sands and attorneys Benjamin Crump and Natalie Jackson were in the office when the call was played.

O'Mara asked her if anyone had listened to the 911 tape alone and she said Martin's father had, but added that he never told her that he had listened to the recording previously.  Tracy Martin initially told Sanford police that he didn't think the screams were his son's voice.

"I heard my son screaming," Fulton said upon further questioning.

"You certainly had to hope it was you son screaming in the 911 call?" O'Mara asked Fulton.

"I didn't hope for anything. I just simply listened to the tape," Fulton responded. Fulton said she was the first in the room to react.

Fulton said no one told her before the playing of the 911 call that she would be listening to screams to prepare herself for any possible "trauma."

During redirect, de la Rionda asked about the "hope" she was questioned about by the defense.

"Were you still hoping he would still be alive?" de la Rionda asked.

"I was hoping he still was alive," Fulton said.

"Did you enjoy listening to that?" de la Rionda said.

"Absolutely not," Fulton said.

O'Mara then asked, "You certainly were hopeful that your son that did nothing that would have lead to his own death?"

"What I hope for is this would have never happened and he would still be here. That's what I hope," Fulton said. 

Later, de la Rionda showed Fulton the button Trayvon Martin was wearing when he was shot and she confirmed it was her son's.

The state also called Martin's 22-year-old brother, Jahvaris Fulton, to testify. He said Tracy Martin wasn't his biological father but he was "the only dad I knew."

Jahvaris Fulton said he and Trayvon Martin were "very close." He identified his brother's screams in the call.

He said he's heard his brother yell, but "not like that."

O'Mara cross-examined Jahvaris Fulton, asking him if he told a reporter on March 31, 2012, "I think it was my brother's screams, but I'm not completely positive."

"I guess I didn't want to believe it was him and I guess that's why during that interview I said I wasn't sure," Jahvaris Fulton said when questioned about it by O'Mara, adding that he was clouded by "shock, denial and sadness."

The defense noted the TV interview was nearly two weeks after he initially listened to the calls. O'Mara wanted to play the TV interview in court, but the state objected.

Nelson heard the matter outside the presence of the jury and ruled that it would not be omitted into evidence.

O'Mara asked Jahvaris Fulton if he had listened to the call between hearing it the first time at Sanford City Hall and the TV interview. Jahvaris Fulton said he didn't recall and when asked why, he said it was "emotional" and didn't want to listen to them again, although he said he has since listened to them.

O'Mara asked Jahvaris Fulton when Tracy Martin left his Miami home in regards to him considering Tracy Martin his father figure. Jahvaris Fulton said he was 9 or 10 years old. O'Mara asked if Trayvon Martin was spending more time with Tracy Martin than his mother. Jahvaris Fulton said both he and Trayvon Martin spent a lot of weekends at his father's house.

During redirect, prosecutor John Guy asked if it was "emotionally difficult" to hear the 911 calls with the screams in the background and how many more times he's listened to the calls.

"Do you now believe it's Travyon Martin's voice on that tape?" Guy asked.
