SANFORD, Fla. - BREAKING DEVELOPMENTS:
Judge Nelson rules she will allow toxicology report showing TCH, or marijuana, in Trayvon Martin's body at time of death.
Trayvon Martin's father has testified that he never denied it was his son's voice in screams for help on a 911 call.
Tracy Martin said Monday that he merely said he couldn't tell if it was Trayvon Martin after his first time listening to the call.
Tracy Martin's testimony came after the lead investigator testified that Tracy Martin had answered "no" when he asked if the screams belonged to Trayvon Martin.
While on the stand, Martin said he didn't believe lead investigator played every 911 call for him, but did play the call with the "fatal shot."
Convincing the jury of whose voice is on the tape is important to both sides because it would help jurors decide who was the aggressor in the confrontation that left Martin dead. Relatives of Martin's and George Zimmerman's have offered conflicting opinions about who is heard screaming.
Earlier on Monday, the lead detective in George Zimmerman's second-degree murder case also testified that Trayvon Martin's father told him that screams for help on a 911 call weren't his son's.
Officer Chris Serino was called by the defense to testify about a meeting with Martin's father in the days after the Miami teen was fatally shot by Zimmerman last year.
At the meeting, when Tracy Martin listened to the 911 recording and was asked if it was his son, Tracy Martin said "no," Serino said.
"He looked away and under his breath he said `no'," Serino said.
Tracy Martin was in the courtroom as Serino recounted the meeting.
Under cross examination, prosecutor Bernie de la Rionda suggested that Tracy Martin may have been in denial about his son's death and uttered, `no."
"It could be perceived as denial," Serino said.
The investigator's testimony was just the latest effort to determine who was crying for help on the 911 calls. Convincing the jury of whose voice is on the tapes is important to both sides because it would help jurors decide who was the aggressor in the confrontation that left Martin dead. Relatives of Martin's and Zimmerman's have offered conflicting opinions on previous days about who is heard screaming.
Another investigator, Office Doris Singleton, backed up Serino's account of Tracy Martin's initial reaction to the 911 call.
A series of Zimmerman's friends on Monday testified that the screams on the recording were their friend, and the 911 call was played multiple times in the courtroom.
After the call was played for Sondra Osterman, defense attorney Mark O'Mara asked who it was.
"Yes, definitely. It's Georgie," said Osterman, who testified she first met Zimmerman in 2006 while working with him at a mortgage company. Osterman and her husband, Mark, describe themselves as the best friends of Zimmerman and his wife.
The emergency call captured the confrontation between Zimmerman and Martin shortly before Zimmerman fatally shot the teen. Zimmerman's mother and uncle testified last Friday it was Zimmerman screaming. Martin's mother and brother also took the witness stand last Friday to say the voice belongs to Martin.
Zimmerman himself once said during a police interview that the screams didn't sound like him, though he and his family later said the screams were his.
Prosecutors had wanted to introduce as witnesses two audio experts who said the voice belonged to Martin and ruled out Zimmerman's voice. But Judge Debra Nelson prohibited the audio experts from testifying, saying their methods were unreliable.
Zimmerman, a former neighborhood watch volunteer, has pleaded not guilty to second-degree murder and says he shot Martin in self-defense during a scuffle in the townhome complex where he lived. Martin was there visiting his father and his father's fiancee.
Prosecutors contend that Zimmerman was profiling Martin and perceived the teen as someone suspicious in the neighborhood, which had been the site of a series of break-ins.
Prosecutors were also seeking Monday to stop defense attorneys from presenting an animated depiction of the fatal fight. Their motion requests that the animation not be mentioned or played at Zimmerman's trial, claiming it would only confuse jurors. They said the animation doesn't show a murder weapon, only approximates positions based on witness accounts and artificially depicts lighting conditions.
Defense attorneys hadn't immediately filed a response. Prosecutors said in their motion that the animation commissioned by the defense was created by employees of the animator re-enacting the fight
