SANFORD -- Defense attorneys presented a parade of witnesses Monday who testified, one by one, the chilling screams on a 911 call came from their friend, George Zimmerman.
And jurors soon will learn Trayvon Martin had marijuana in his system Feb. 26. 2012, the night Zimmerman shot him. Seminole County Circuit Judge Debra Nelson, who previously held off on a ruling on the toxicology report's admissibility, said Monday she would let the defense present the information to jurors in Zimmerman's second-degree murder trial, now entering its third week of testimony.
Prosecutors rested the state's case Friday.
Defense attorneys seemed to gain momentum Monday with testimony from two Sanford police investigators who said Tracy Martin, father of slain 17-year-old Trayvon, told them the screams on the recorded call did not belong to his son.
But, in what legal observers called a risky move, defense lawyers called Tracy Martin to the stand. He remembered a different version
of what he told police after they played him the 911 call two days after Zimmerman fatally shot Trayvon in a gated Sanford community.
Investigator Chris Serino "basically just said, 'Do you recognize the voice?'" Martin said. "My response was... I pushed my chair away from the table, shook my head and said I can't tell. I never said, 'No, that wasn't my son's voice.'"
Later, Martin said, he recognized the voice as his son's.
"After listening to the tape maybe 20 times, I knew that it was Trayvon's voice."
Monday's list of defense witnesses -- the first five, including two married couples, said they believed they heard Zimmerman yelling for help on the 911 call -- served to counter testimony Friday from Trayvon's mother and brother, who identified the voice crying out for help as belonging to the slain Miami Gardens teen.
The defense witnesses also offered testimony aimed at bolstering the image of the defendant, a former Neighborhood Watch coordinator who prosecutors are painting as a frustrated, wannabe cop. Zimmerman, 29, maintains he acted in self-defense after Trayvon violently attacked him. Zimmerman faces up to life in prison if convicted as charged.
One couple, John Donnelly and Leanne Benjamin, spoke of Zimmerman in parent-like fashion. She talked about mentoring the defendant in starting his own business, while her husband choked up a bit when he described buying Zimmerman suits for the trial and teaching him to tie a Windsor knot.
Another Zimmerman pal, Mark Osterman, previously called as a state witness, took the stand Monday as a defense witness, telling jurors about teaching his "best" friend about firearm safety. Osterman's wife, Sondra, who also took the stand, repeatedly referred to Zimmerman as "Georgie" and identified the voice on the 911 call as Zimmerman's.
"The voice witnesses on both sides will probably cancel each other out, especially because each one has a built-in bias," said former Miami-Dade prosecutor David Waksman, who watched part of Monday's testimony. "But for the defense, these witnesses were important to humanize the defendant. They want him to be Georgie, George, your next-door neighbor."
Although several neighbors in Sanford's Retreat at Twin Lakes community placed 911 calls the night of Trayvon's death, one particular call from Jenna Lauer captured several harrowing seconds of yelps followed by a single gunshot.
The "Lauer call," as defense attorney Mark O'Mara referred to it, was played multiple times in court Monday so witnesses could say who they thought was screaming.
"There's absolutely no doubt in my mind, that is George Zimmerman, and I wish to God I did not have that ability to understand that," Donnelly testified. He said his experience as a U.S. Army medic in Vietnam taught him to identify screams in traumatic situations.
On cross-examination, Donnelly said he had given $4,700 in clothes, money and food to Zimmerman after the shooting. He also acknowledged he had never heard Trayvon's voice, which meant he was unlikely to have been able to identify it on the 911 recording.
Prosecutor Bernie de la Rionda countered O'Mara's playing of the Lauer call by playing, on cross-examination, Zimmerman's non-emergency call to police when he reported Trayvon as suspicious. In that call, Zimmerman uttered profanities that the state has argued showed ill-will, spite or hatred -- elements of second-degree murder.
Jurors, who have heard the recordings about a dozen times during the trial, remained attentive but took only occasional notes as the audio played.
Trayvon's parents stayed in the courtroom throughout the replaying of the 911 call. Earlier in the trial, they had been leaving the room before the graphic tape was played.
On the witness stand Monday, Trayvon's father said the sounds still haunt him.
"You realized that was the shot " de la Rionda began to ask.
"That killed my son, yes," Tracy Martin said.
"My world from that point and until today has just been turned upside down," Martin continued. "I was listening to his last cry for help, listening to his life being taken, trying to come grips with the fact that Trayvon isn't here...
"I was trying to figure out ... why did the defendant get out of his vehicle and chase my son?"
The judge's ruling on the marijuana issue, made after jurors were dismissed for the day Monday, was a big win for the defense and a correct decision, legal experts said. A state witness, assistant medical examiner Dr. Shiping Bao, opened the door for the drug report last week when he revealed, outside the presence of jurors, he believed marijuana in Trayvon's system could have had an effect on him that night.
The decision to allow testimony about the marijuana use was "not even close," said Miami defense attorney Brian Tannebaum, because prosecutors have brought in so much of Zimmerman's past, including his college courses, interest in law enforcement and physical training.
"What's good for one side is good for another. It's pretty clear," Tannebaum said.
Former Miami-Dade prosecutor John Priovolos said that while the defense could make an argument that the teen's use of marijuana made him aggressive, the evidence also could be seen as a significant blow to the credibility of a key state witness: Rachel Jeantel.
The Miami teen told jurors she was on the phone with Trayvon moments before his death and heard him describe Zimmerman as a "creepy-ass cracker" who was following him.
"Their best bet is to say Trayvon is not a bad person because he was smoking dope, but his statements to Rachel that night might not be credible because of the drug use," Priovolos said.
