Feb. 26, 2012 -- Trayvon Martin is walking to the home of his father's fiancee after purchasing items from a 7-Eleven store in Sanford. George Zimmerman, a neighborhood watch volunteer, spots Martin at approximately 7 p.m. and calls police. "We've had some break-ins in my neighborhood, and there's a real suspicious guy," Zimmerman tells police.
Feb. 26, 2012 -- Roughly seven minutes after Zimmerman's call to police, authorities receive a 911 call from an individual reporting a fight. During the call, the dispatcher hears a gunshot in the background and sends police units to the location. Responding officers discover that Martin has been shot in the chest. The teen is unresponsive and pronounced dead at the scene.

Our parents: Mr. & Mrs. Zimmerman along with our sister are in court today supporting George. Despite safety considerations, the time was right to do what they could to visibly advocate for George's innocence. Our parents have avoided showing their face on-camera because of numerous death threats directed at our entire family. Our parents have served as primary caretakers for our grandmother.
June 20, 2013 -- Day nine of jury selection begins.
Zimmerman's defense attorney Mark O'Mara addresses the potential jurors.
"We have labels that we put on people. We have victims and we have defendants ... and George Zimmerman has been called a defendant, as if he has something to defend," says O'Mara. "The jury decides whether or not the state has proven its case beyond a reasonable doubt."
O'Mara talks to the potential jurors about how "reasonable doubt" and "direct evidence" play a role in the case.
Afterward, De la Rionda asks to strike P67, for cause. The prosecutor says the potential juror has limited understanding of the English language and has said serving would be a hardship.
O'Mara objects, saying the juror can understand English.
The judge declines to excuse the juror for cause.
The judge then lists each of the jurors and asks both sides if they have peremptory strikes against any of them.
B12 - Strike by prosecution because of comments she made visiting Zimmerman's website.
B86 - Strike by prosecution because she said Trayvon had been expelled from school and shooting would not have occurred if that had not happened.
B29 - No strike.
E6 - Strike by prosecution because she said she was concerned about being sequestered and expressed an opinion about the difficulty of sending someone to prison. The judge denied the strike.

B7 - Strike by defense.
B37 - No strike.
B51 - No strike.
E40 - No strike.
B35 Strike by prosecution.
E54 - No strike.
E73 - No strike.
M75 - Strike by defense. Defense said they are concerned because she is a friend and co-worker of a witness in the case and did not disclose it.
B72 - No strike.
E22 - Strike by defense. Defense concerned because she said police should have been more active and her pastor of 19 years, for whom she works, wrote a "pointed letter" to the Orlando Sentinel that was "very pro-Trayvon." The pastor also allegedly gave a sermon that he was in favor of Martin's side. The defense said they consider her to be "somewhat stealth" because she did not disclose the information.
E13: No strike.
The Jury Is Chosen:
E6, E40, B37, B51, B29 and B76.
All six Zimmeman jurors are women. Six are white and one is Hispanic.
The alternates are: E54, E73, B72, and E13.
The jury has been sworn in.
June 24, 2013 -- The prosecutor’s opening statement in the long-awaited murder trial recounted what George Zimmerman told a police dispatcher shortly after he spotted Martin: "F------ punks. These a-------. They always get away."
According to Prosecutor John Guy, Zimmerman was fed up with "punks" getting away with crime and shot Trayvon Martin "because he wanted to," not because he had to.
Defense attorney Don West follows Guy’s statement with a lackluster knock-knock joke about the difficulty of picking a jury for the case.
"Knock. Knock," says West.
"Who is there?"
"George Zimmerman who?"
"All right, good. You're on the jury."
West quickly changes gears and counters the prosecution, saying Martin sucker-punched Zimmerman and pounded his head against a concrete sidewalk.
"He had just taken tremendous blows to his face, tremendous blows to his head," says West.
With that, the prosecution calls their first witness, a custodian of police dispatch calls, to the stand. She testifies about 911 calls and is followed by a convenience store clerk who sold Martin Skittles and the 911 dispatcher who took Zimmerman's call about Martin.
June 25, 2013 -- Notable witness on day two include George Zimmerman's neighbor, Selene Bahadoor (pictured) and Wendy Dorival, former coordinator of the Sanford Police Department's neighborhood watch program
Bahadoor describes being drawn to a window in her home the night of the shooting when she heard movement outside.
"I saw figures, arms flailing," says Bahadoor.
Dorival testifies she worked with Zimmerman to set up the “Neighborhood Watch” program in his neighborhood.
"[Participants] are the eyes and ears of law enforcement," Dorival says. "They're not supposed to take matters into their own hands."
June 26, 2013 -- George Zimmerman’s former neighbor, Jayne Surdyka, testifies on the third day of his murder trial. She says she thought she heard multiple gunshots.
"I truly believe the second yell for help was a yelp," says Surdyka. "It was excruciating. I really felt it was a boy's voice."
Rachel Jeantel (pictured), the young woman who was on the phone with Trayvon Martin the night he was shot, is also called to testify on day three.
According to Jeantel, Martin was aware he was being followed by someone.
"He kept complaining the man was watching him," says Jeantel.
Martin allegedly told her the man watching him was a "creepy-ass cracker." She claims she then heard a bump and Martin say "get off." The call was then cut off and she never spoke to Martin again.
During cross-examination, Jeantel, admits to lying about her age after the shooting.
June 27, 2013 -- Rachel Jeantel is called back to the stand on day four of the trial. Defense attorney Don West confronts her about differing accounts she has allegedly given regarding what happened before Martin's killing.
"That's real retarded, sir," Jeantel says when West suggests Martin may have confronted Zimmerman.
Afterward, a mobile phone manager testifies about Martin's cell phone records and a former neighbor of Zimmerman says she heard someone screaming outside her townhome on the night Martin was shot.
"They were being hurt," says Jenna Lauer.
June 28, 2013 -- Notable witness on day two include John Good (pictured), who lived at the Retreat at Twin Lakes, and police officer Ricardo Ayala and Timothy Smith.
According to Good, he was watching TV on the night of the shooting when he heard a "faint" noise come from outside his home. He could not tell which direction the noise came from and "didn't think anything of it" until he heard further noises.
"I yelled out 'What's going on?'" says Good.
He then looked outside.
"It looked like there were strikes being thrown or punches being thrown ... it could have also been holding down," Good says.
Officer Ricardo Ayala, one of the first police officers who responded the night of the shooting, tells the court he saw Martin stomach-down on the ground and asked to see his hands. Ayala recalls that he received no physical or verbal response. He says he did not see any movement from Martin's body.
He later discovered the gunshot wound on Martin.
Officer Smith is another member of the Sanford Police Department who responded to The Retreat at Twin Lakes complex on the night of the shooting.
Smith explains the rainy weather conditions and how he came to the scene.
Officer Smith describes how he first approached Zimmerman and how Zimmerman held his gun at the time. Smith said that he asked Zimmerman if Martin was shot and who shot him, to which Zimmerman replied that "he did and he was still armed."
Almost immediately after turning toward the patrol car, Smith recalls Zimmerman "stated to me that he was yelling for help and that nobody would come help him."
July 1, 2013 -- The prosecution has called Dr. Hirotaka Nakasone (pictured) to the stand. He works in the operations division of the FBI field office in Quantico, Virginia. He specializes in forensic examinations of audio clips.
Dr. Nakasone said he received recordings in this case in March 2012.
"All together eight recordings were given to us," says Nakasone.
Dr. Nakasone said he examined the 911 call that contains sounds of someone yelling for help.
"The case was assigned to me to do voice comparison ... We listened to the entire conversation ... When I was listening I could hear voices in the background -- someone yelling for help," says Nakasone.
Nakasone says he could not compare the voices.
"That type of voice sample is not fit for the purpose of voice comparison," Dr. Nakasone said of the 911 call containing the screams. "I don't think it would be possible to determine the age by listening."
Dr. Nakasone is followed on the stand by Doris Singleton, a police officer with the Sanford Police Department.
According to Singleton, she was at the police department the night of the shooting and interviewed Zimmerman.
"I did not get any indication that he was under the influence of anything," says Singleton.
She then recounts what Zimmerman told her: "He jumped out from the bushes and said, 'what the f--k's your problem,'" Zimmerman said of Martin.
He said Martin attacked him and punched him.
"I said 'Help me, help me, he's killing me,'" Zimmerman said.
Zimmerman said after he shot Martin the teen said, "You got me."
July 2, 2013 -- The prosecution has called Mark Osterman. He is an officer with the Federal Marshal Service. He has known Zimmerman for "at least five years" and consider him the best friend he has ever had.
According to Osterman, Zimmerman told him he was going for his phone when Martin punched him "squarely in his face." Afterward he said Martin slammed Zimmerman's head into the sidewalk.
"George began screaming for help at that point," says Osterman.
The next witness is Dr. Valerie Rao (pictured). She is the District four medical examiner.
Rao examined the reenactment of the shooting, photos, medical records, the medical examiner report, autopsy photos and other relevant evidence.
"They were so minor that sutures were not required," Rao says of Zimmerman's injuries.
July 3, 2013 -- The prosecution calls Sonja Boles-Melvin (pictured) to the stand. She works at the Seminole State College of Florida.
According to Boles-Melvin, Zimmerman applied for degree in October 2011. He anticipated graduating in spring 2012.
Boles-Melvin is followed by Lt. Scott Kearns, a police officer with Prince William County Police in Virginia.
Kearns testifies Zimmerman filed an application to become a police officer with his department. The application was rejected in July 2009 because Zimmerman had bad credit.
After hearing witness testimony about college courses Zimmerman took on criminal litigation and investigations, Anthony Gorgone is called to the stand. He is a crime lab analyst with the Florida Department of Law Enforcement.
Gorgone testifies about blood evidence and reveals items of clothing he had inspected had been packed in plastic bags, which can destroy DNA evidence.
"Both sweatshirts were still wet when I opened the package," says Gorgone.
July 5, 2013 -- The prosecution calls Sybrina Fulton (pictured) to the stand. She is Trayvon Martin's mother.
Fulton says she recognizes the screams on the 911.
“I heard my son screaming," says Fulton.
Trayvon Martin’s older brother, Jaharvis Fulton, says the same thing. However, on cross-examination he admits to previously telling a reporter he was "not completely positive" his brother was the one screaming on the 911 call.
The prosecution next calls Shiping Bao to the stand. He is the medical examiner who performed Martin's autopsy.
"The cause of death was gunshot wound to chest," says Bao.
Bao has difficulty remembering many details of the case and admits to changing his opinion on how long Martin would have lived after he was shot.
"All I know is I did autopsy, he was shot and he is dead … I don't remember anything," says Bao.
After Bao the State rests its case.
The first defense witness is Zimmerman’s mother, Gladys Zimmerman.
Asked by defense attorney Mark O’Mara who can be heard screaming on the 911 call, she replies, “My son George."
George Zimmerman’s uncle, Jorge Maza, states the same thing when he takes the stand minutes later.
"It was George," says Maza.
July 8, 2013 -- Sondra Osterman is the third witness called by the defense. Her husband Mark is Zimmerman's best friend.
Osterman listens to the defense play the 911 and she says she believes “it's Georgie," that can be heard yelling in the background.
Osterman's husband Mark follows her on the stand. Osterman said Zimmerman took a gun course for a concealed carry permit. He said he also advised Zimmerman on gun safety.
Osterman said he has heard the 911 and believes the person yelling is Zimmerman.
"It just sounded like George," says Osterman.
Several other of Zimmerman’s friends take the stand after Osterman and also testify they believe Zimmerman is the one screaming on the 911 call.
The defense then calls Chris Serino to the stand. He is the officer with the Sanford Police Department who spoke with Martin's father while Singleton was present.
Serino acknowledges he met with Martin's father in his office a day or two after the shooting, to bring him "up to speed on the progress of the investigation."
Serino says he played the 911 recording with the screams for Tracy Martin during the meeting and asked Martin if that was his son's voice in the background.
"He looked away and under his breath ... said 'No,'" says Serino.
After Serino the defense calls Adam Pollock (pictured) to the stand. He owns a local gym.
"He came to the gym to lose weight and get into shape," Pollock says of Zimmerman.
Pollock says he trained Zimmerman for about a year and describes him as “physically soft" and not very strong.
The defense then calls Trayvon Martin's father to the stand.
Tracy Martin says detective Serino played the 911 call for him, but denies he said the voice he heard was not his son.
"I [said I] can't tell ... but I never said that wasn't my son's voice," says Martin.
July 9, 2013 -- The defense calls Dr. Vincent Di Maio to the stand. He is a forensic pathologist.
Di Maio explains the procedure for handling evidence and says wet clothing must be dried and should never be placed in plastic.
He also says it is his opinion that Zimmerman’s gun, "at the time of discharge the gun was against [Martin’s] clothing" and was two to four inches away from Martin's skin.
The angle of the shot is consistent with Martin being on top of Zimmerman at the time he was shot, says Di Maio.
July 10, 2013 -- The defense calls Dennis Root to the stand. He is a self-employed law enforcement investigator and private detective. He reviewed the 911 calls, police reports, autopsy reports and other relevant evidence in the case.
"Based on injuries I saw ... they are consistent with a fight," says Root, referring to the photos of Zimmerman's injuries.
The last witness called by the defense is Zimmerman’s father Robert Zimmerman Sr. (pictured).
Defense attorney Mark O'Mara asks the elder Zimmerman if he has an opinion on who can be heard yelling on the 911 call.
"It's my son George," says Zimmerman.
With that the defense rests.
July 11, 2013 -- Prosecutor Bernie de la Rionda (pictured) gives the closing statement for the State.
"A teenager is dead. He is dead through no fault of his own. He is dead because another man made assumptions. That man assumed certain things. He’s dead not just because the man made those assumptions, [but] because he acted upon those assumptions and unfortunately because his assumptions were wrong, Trayvon Benjamin Martin no longer walks on this earth," says de la Rionda.
The prosecutor says Zimmerman “profiled [Martin] as a criminal ... and that is what led to his death."
July 12, 2013 -- Mark O’Mara (pictured) gives the closing argument for the defense.
O'Mara says he is concerned about the jurors forming an opinion before they begin deliberating.
"You’re completely unused to it. You don’t know how to apply a standard beyond a reasonable doubt, you just don’t," says O'Mara. "You can’t help but have a first impression."
O'Mara puts on a pinkie ring and sunglasses as an example of something that could cause someone to formulate a first impression.
"Be careful with your common sense because common sense is the way we run our everyday lives, the way we make those snap decisions we have to make every day," says O'Mara.
O'Mara has asks everyone in the courtroom to be quiet.
"That's how long Trayvon Martin had to run -- about four minutes," says O'Mara. "He had four minutes ... before that fight started ... Do you have a doubt as to what happened and what Trayvon Martin was doing for four minutes … You can run a mile in about four minutes if you're in decent shape."
He holds up a chunk of concrete and says, "That is not an unarmed teenager."
Prosecutor Guy gave the rebuttal closing for the state.
"There's only two people on this earth who can tell what happened. One of them can't testify and the other one lied," says Guy.
With that the judge reads the final instructions to the jury.
Judge Nelson explains to the jury that they must find the case presented by the prosecution to be true beyond a reasonable doubt in order to convict Zimmerman.
The jury is now deliberating the case.
July 12, 2013 -- After 16 hours of deliberations the verdict is in.
The jury has found George Zimmerman not guilty.
The judge told Zimmerman his bond will be released and his GPS monitor will be removed.
