"He didn't have bruised knuckles, he didn't have swollen hands. The only injury to his hand that was capable of being photographed was a small abrasion with his left right finger. Trayvon Martin was left-handed," Guy said.

Guy said the jury will hear a "bone-chilling 911 call" where Martin was screaming in the background, stopping when Zimmerman shot him.

The state's opening statements closed by Guy saying Zimmerman "profiled" Martin.

"George Zimmerman didn't shoot Trayvon Martin because he had to. He shot him because he wanted to," Guy said, thanking the court for their time.

Attorney Don West made much longer opening statements than the state's, filled heavily with recitation of timeline facts for the defense, starting out soft-spoken and quoting one of the potential jurors by saying "there are no winners."

"This is a sad case of course ... one man lost his life, another is fighting for his," West said. "I think the evidence will show this is a sad case that there are no monsters here."

"George Zimmerman is not guilty of murder," West continued.

After the state objected to West referring to motherly advice, he said, unattributed, "sometimes you have to laugh to keep from crying."

"I'd like to tell you a little joke," West said, before telling a knock-knock joke about being on the Zimmerman jury. Only one juror grinned. West later apologized for his joke.

West first showed the jurors the aerial view of the neighborhood where Zimmerman fatally shot Martin-- The Retreat at Twin Lakes.

West then told the jury the events of Zimmerman leaving the house on Feb. 26, 2012 to go to Target to get food for his lunches. West said Zimmerman was not "patrolling" that night.

Little did Zimmerman know he was going to be "sucker punched in the face, head pounded into the concrete," West said.

West said that Zimmerman participated in Neighborhood Watch because the community asked him to be involved in it as the Sanford police liaison. He said Zimmerman called the non-emergency number to report the suspicious activity.

West called it "absolutely untrue" that Zimmerman was told by a dispatcher not to follow Martin while he was still in his truck.

"You'll know when Zimmerman got out of the car and you'll know what he was doing when the call ended," West continued, explaining the defense's timeline for the night of the shooting.

The defense then played the non-emergency call in which Zimmerman reported suspicious activity the night of the shooting, where Zimmerman is heard describing Martin as being "up to no good."

As the call was playing, Zimmerman didn't react as the dispatcher is heard asking him if he is following, as he responds "yes," to which the dispatcher says "OK we don't need you to do that." West said Zimmerman then stopped following Martin.

West said that Zimmerman was "following Trayvon Martin at a distance, reporting what he saw to police." West also said when the dispatcher asked which way Martin was running, Zimmerman took that as a cue to get out of his vehicle to find out.

West then focused on how dark it was out that night, and that's why Zimmerman told authorities to call him when they got on scene instead of giving an exact address.

The non-emergency call was then played for the second time in the defense's opening statements.

West then discussed Witness 8's phone call with Martin and said that it tells the moment that it got physical. He said Martin decided to confront Zimmerman and had plenty of time to go home, possibly hiding in the dark.

"That's basically the last thing she heard," West said, "That's when Trayvon Martin made the decision to confront George Zimmerman and say 'what are you following me for?'"

West then played the 911 call from witnesses with screams and the gunshot in the background. Martin's mother, Sybrina Fulton, walked out of the courtroom as the 911 calls were played.

"Those are the screams of someone in a life-threatening situation," West said. West said there's no scientific way to identify the person screaming in the background of the 911 call.

"I would expect Trayvon Martin's parents to say screams were his," West said, adding that Sybrina Fulton "wants it to be" her now-deceased son. West then told the jurors about how Martin's father, Tracy, told Sanford police officers the screams weren't his son's. Zimmerman's family recognized Zimmerman's screams on the 911 call, West added.
