Trayvon Martin Crime Scene Photos Shown To George Zimmerman Jurors (GRAPHIC PHOTOS)

Jurors in George Zimmerman's murder trial on Tuesday were shown graphic photos of Trayvon Martin's body while a police officer testified about trying to resuscitate the teen.

Sgt. Anthony E. Raimondo, who works for the Sanford Police Department, testified he was one of the first officers to respond to Martin's shooting on the night of Feb. 26, 2012.

Raimondo said Martin was face-down and unresponsive. He said he turned the teen over and began to give him CPR but heard air escaping "in a manner that it was not supposed to."

The police officer said he determined the air was escaping from the gunshot wound to Martin's chest. He continued in his attempts to resuscitate the teen until paramedics arrived and pronounced Martin dead.

Assistant State Attorney John Guy displayed several graphic photos of Martin and his injuries during Raimondo's testimony. Defense attorney Mark O’Mara also displayed graphic photos of Martin's body during his cross-examination of the witness.

The photos had an obvious impact on those seated in the courtroom and were so disturbing to Martin's family members that his mother averted her eyes and his father left the courtroom.

Zimmerman, 29, shot and killed Martin as the unarmed teen was walking back to the home of his father's fiancee from a Sanford, Fla., convenience store with a bag of candy on the night of Feb. 26, 2012.

The defendant has pleaded not guilty in Martin's death. The defense team says Zimmerman was attacked by Martin and acted in self-defense. Prosecutors allege Zimmerman profiled Martin before killing the teen.

Zimmerman faces a possible sentence of life in prison if he is convicted.

George Zimmerman Trial Live Updates: Opening Statements In Murder Trial

More than a year after the shooting of 17-year-old Trayvon Martin sparked controversy across the country, prosecution and defense lawyers will finally get to outline their cases to a Florida jury.

Opening statements are set for Monday morning in George Zimmerman's second-degree murder trial. The proceedings start following a marathon nine days of jury selection to find objective candidates who had not already formed an opinion about Zimmerman's guilt or innocence.

Jury selection in Zimmerman’s trial concluded Thursday, with a panel of six female jurors chosen to decide his fate. The jurors and four alternates were sequestered at an unknown location over the weekend in order to eliminate the possibility of their exposure to outside influences.

Monday's opening statements in Seminole County Circuit Court will preview the essence of the trial.

Defense attorneys Mark O'Mara and Don West are representing Zimmerman, and the lead prosecutor for the state of Florida is Bernie de la Rionda.

Zimmerman's attorneys claim he acted in self-defense when he was attacked by Martin while on a neighborhood watch patrol. The prosecution will likely suggest Zimmerman, who is Hispanic-American, profiled and murdered Martin.

The defense has not yet decided if Zimmerman will take the stand. That decision will likely be made after the prosecution presents its case.

The long-awaited proceedings have piqued the interest of the nation and fed a national debate about racism, self-defense laws and gun control.

The trial, before Circuit Judge Debra Nelson in Seminole County, is expected to last more than a month. During that time, both sides will try to convince the jury of their version of the events of Feb. 26, 2012.

If convicted, Zimmerman could face a possible sentence of life in prison.

Opening statements are scheduled to begin at 9 a.m. EST.
