SANFORD, Fla. -- A Florida judge has ruled that jurors at George Zimmerman's trial may be told that Trayvon Martin had small amounts of marijuana in his body when he died.

Judge Debra Nelson on Monday denied a prosecution request to keep out parts of a toxicology report that shows Martin had small amounts of marijuana in his system.

Prosecutors argued the information would be prejudicial.

But defense attorneys said it was relevant since Zimmerman believed Martin was under the influence at the time he spotted him in his neighborhood.

Zimmerman is pleading not guilty to second-degree murder. He is claiming he fatally shot Martin in self-defense.

THIS IS A BREAKING NEWS UPDATE. Check back soon for further information. AP's earlier story is below.

Trayvon Martin's father testified Monday that he never denied it was his son's voice screaming for help on a 911 call, contradicting police officers' earlier testimony at George Zimmerman's second-degree murder trial.

Tracy Martin said that he merely told officers he couldn't tell if it was his son after his first time listening to the call.

"I never said that wasn't my son's voice," said Tracy Martin, who added that he concluded it was his son after listening to the call as many as 20 times.

Tracy Martin's testimony came after the lead investigator probing Martin's death testified that the father had answered "no" when the detective asked if the screams belonged to Trayvon Martin. Officer Chris Serino played the 911 call for Tracy Martin in the days immediately following Trayvon Martin's death in February 2012.

"He looked away and under his breath he said `no'," Serino said of Tracy Martin.

Officer Doris Singleton backed up Serino's account.

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.

During cross examination of Serino, 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. 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 wearing motion-capture suits.

Under cross-examination, prosecutor Bernie de la Rionda implied that Sondra Osterman and her husband, Mark, had a stake in the outcome of the trial because they had written a book about Zimmerman's case and were donating the proceeds to their friend.

Mark Osterman took the witness stand after his wife to testify about how Zimmerman had chosen and purchased his firearm. He testified that Zimmerman could shoot with both hands, and he also said he recommended keeping the gun loaded.

He said it was Zimmerman's voice screaming when the 911 call was played for him in the courtroom.

Former co-worker Geri Russo also testified it was Zimmerman yelling on the call, as did John Donnelly and Leanne Benjamin, a married couple who became good friends with Zimmerman and his wife.

The prosecutor also played for Sondra Osterman a nonemergency police call Zimmerman made to report Martin walking through his neighborhood. In the call, Zimmerman uses the words, "F------ punks. These a-------. They always get away." Sondra Osterman identified the voice as Zimmerman's.

When asked by O'Mara if she detected ill will, spite or hatred in his voice, she answered no.

Prosecutors must show that Zimmerman acted with ill will, spite or a depraved mind in order to get a second-degree murder conviction.

Defense attorneys also called the owner of a gym where Zimmerman had gone to lose weight to explain to jurors the mixed-martial arts fighting method called "ground and pound." Defense attorneys have said that Martin slammed Zimmerman's head into the sidewalk while he was on top of him in "a ground and pound" maneuver. To demonstrate the move, gym owner Adam Pollock straddled O'Mara on the courtroom floor. Pollock testified that Zimmerman trained in the form of fighting known as grappling but was an unaccomplished fighter.

"He was physically soft," said Pollock when asked to rank Zimmerman's athletic skill on a scale of 1 to 10.

"[Martin's family] suffered a tragedy ... Nothing can bring back Trayvon Martin ... But I'm not going to shy away from the fact that the evidence showed George Zimmerman did nothing wrong," O'Mara said.

(Washington, DC)— Dan Gross, President of the Brady Campaign to Prevent Gun Violence today called the verdict, “part of a tragic event that could have easily been prevented.”

Gross said, “There is sharp disagreement over the verdict, but there can be no disagreement over the reason why Trayvon Martin is dead. George Zimmerman had a gun that night, and the state of Florida allowed him to carry it virtually anywhere despite a violent history. Virtually anybody roaming our neighborhoods with hidden handguns is the gun lobby's vision, but it is not the vision of the rest of the American public, truly committed to safer communities. We will work as long, and as hard as it takes to prevent more tragedies like Trayvon Martin's. We recognize, at the end of the day, this is an enormous tragedy and a young man lost his life. Our sympathies continue to go out to Trayvon’s family.”

The Brady Campaign has been one of the leaders in fighting against “Stand Your Ground” or so called, “shoot first” laws like the one in Florida. As evidenced by the tragic shooting of Trayvon Martin, these laws have deadly consequences. They promote a dangerous mentality and misperception about weapons, by overemphasizing their value in self-defense relative to the other dangers that they pose.

In the end, George Zimmerman's mentality, and what emboldened him to approach Trayvon, may be debatable. What is not debatable, though, is the fact that Trayvon Martin is dead because Zimmerman had a gun. Zimmerman was given a concealed carry permit by the state of Florida despite an arrest record and a history of violence, as a direct result of the influence of the gun lobby, and if it weren’t for that, this tragedy never would have happened.

The Brady Center, the legal arm of the Brady Campaign, has been at the forefront in fighting concealed weapons laws. They recently filed an amicus brief along with the parents of Trayvon Martin, asking the entire United States Court of Appeals for the Seventh Circuit Court of Appeals to review and reverse a 2-1 decision that held Illinois law restricting the public carrying of firearms unconstitutional.

“Allowing deadly semi-automatic weapons on the streets does not make a community safer. By arguing for a broad constitutional right to carry hidden handguns, the gun lobby wants to deprive law enforcement of the tools it needs to keep guns off the streets. The American people should be allowed to decide whether they want people like George Zimmerman carrying loaded guns in public places where their children walk home,” said Brady Center Legal Action Project Director Jonathan Lowy. “Most courts have properly recognized that reasonable public safety laws do not infringe on the Second Amendment rights of law-abiding citizens. Courts should listen to the parents of Trayvon Martin and Jordan Davis, who lost their sons to people whose states entitled them to carry guns in public.”

The brief was filed on behalf of the Brady Center to Prevent Gun Violence; Tracy Martin and Sybrina Fulton, parents of Trayvon Martin; Ron Davis and Lucia McBath, parents of Jordan Davis; Major Cities Chiefs Association; and International Brotherhood of Police Officers by attorneys with the Brady Center’s Legal Action Project and the firm Hogan Lovells US LLP.
