Problem:SANFORD – After four days of testimony detailing the witness accounts and forensics in the case against George Zimmerman, an unusual topic stole the show at times on Friday: Combat sports. 
  
 The state and defense battled repeatedly on mixed martial arts, the multi-discipline boxing-like sport usually practiced in an octagonal ring, with regard to both Zimmerman and 17-year-old Trayvon Martin. 
  
 After two days' testimony by the state's star witness ended Thursday, prosecutors on Friday called the man expected to be the defense's star: John Good, a Zimmerman neighbor who told Sanford police that on the night of the shooting he'd seen a black man on top of a lighter-skinned man "just throwing down blows on the guy, MMA-style." 
  
 On the witness stand, Good said he was watching television in the living room of his Retreat at Twin Lakes townhome when he heard noises outside. He opened his glass sliding door and stepped out onto his porch. 
  
 It looked like a "tussle," Good said, adding "I yelled out, 'What's going on?' and 'Stop it,' I believe." 
  
 Good said two people were wrestling, in a straddling position — which defense attorney Mark O'Mara acted out on his knees in court, and Good described with MMA terminology: The "ground and pound." 
  
 The one on top was wearing dark clothes, he said, and the one on the bottom had lighter skin and was wearing white or red. 
  
 Pressed further by O'Mara, Good said he could identify them: "The person who you now know to be Trayvon Martin was on top, correct?" O'Mara asked. 
  
 "Correct," Good replied. 
  
 "And he was the one who was raining blows down on the person on the bottom, George Zimmerman, right?" O'Mara followed. 
  
 Good's response: "That's what it looked like." 
  
 However, Good vacillated on two points that could benefit the state. He said he couldn't say with 100 percent certainty who it was calling out for help — though he thought it was Zimmerman. And he also acknowledged that he didn't see the punches connect, he just saw "arm movement going downward." 
  
 "I couldn't tell 100 percent that there was actually fists hitting faces," he said. 
  
 The MMA-style testimony continued in the afternoon, but this time the Zimmerman team was on the defensive. 
  
 Lindzee Folgate, an Altamonte Family Practice physician assistant who treated Zimmerman Feb. 27, 2012, the day after the shooting, was called to testify on his medical records. Reading a medical history taken Aug. 19, 2011, Folgate testified that due to difficulty sleeping, Zimmerman had "started to exercise intensely with MMA." 
  
 Another record from Sept. 23, 2011, indicated Zimmerman was in MMA training "three days per week." 
  
 Folgate also gave Zimmerman's measurements from the day after the shooting: 5-foot-7.5, 204 pounds. His body mass index rated him obese, she said. The medical records also described Zimmerman, whose mother is Peruvian and who self-identifies as Hispanic, as a white male. 
  
 Zimmerman had two lacerations on his head Feb. 27, Folgate said: 2 centimeters and 0.5 centimeters. Neither needed stitches, she said. Of Zimmerman's nose, Folgate said: "I would say likely broken, it's hard to say definitively." 
  
 No X-rays were taken to confirm that, she said. 
  
 On cross examination, Folgate testified that the cuts, scrapes and bruises to Zimmerman's head could be consistent with having his head slammed into a concrete sidewalk, as Zimmerman says Trayvon did before the shooting. 
  
 O'Mara asked: "Stopping the attack was what allowed him to survive it, wouldn't you agree?" 
  
 "It could have, yes," she said, though she agreed that was speculation when prosecutor Bernie de la Rionda followed up. 
  
 Earlier in the day, Good had testified that though the fight he saw the night of the shooting did move onto the sidewalk, he didn't see Trayvon slamming Zimmerman's head as the Neighborhood Watch volunteer described. 
  
 Jurors also heard Friday from the first people to arrive at the scene after the shooting. 
  
 The first civilian, Jonathan Manalo, said he was the first person to encounter Zimmerman after the shooting. He looked like he'd been in a fight, Manalo said, so the witness took cell phone pictures of Zimmerman's bloodied head. 
  
 While Manalo was on the phone with Zimmerman's wife — at Zimmerman's request — the defendant blurted out a seemingly blunt remark: "Just tell her I shot someone." 
  
 However, Zimmerman also told Manalo "I was defending myself and I shot him," the witness testified on cross-examination. 
  
 The first Sanford police officer to arrive, Tim Smith, also testified Friday, and said he held Zimmerman at gunpoint and handcuffed him after Zimmerman said he was the one who shot the teen. Zimmerman was compliant and calm, but also bloodied and wet, with grass on his clothes, Smith said. 
  
 Both Manalo and another police witness testified that Trayvon's hands were under his body after the shooting. That's an important point for the state, as Zimmerman told police that after the shooting, he climbed on top of the teenager, spread his arms and pinned them to the ground. 
  
 Smith testified that Zimmerman said he'd been crying out for help, as the defense claims. Zimmerman had "sort of a confused look on his face," when he said that, Smith said. 
  
 The trial resumes Monday morning. Among those who still haven't taken the witness stand in the high profile case are lead Sanford police investigator Christopher Serino, the medical examiner who autopsied the Miami Gardens teen and Trayvon's parents, Tracy Martin and Sybrina Fulton. 
  
 Testimony began Monday, after opening statements. Attorneys in the case estimated testimony and evidence would take two to four weeks, and defense attorney Mark O'Mara said Thursday they're on schedule so far.

Thursday, June 27, 2013. Zimmerman has been charged with second-degree murder for the 2012... (Associated Press) 
  
 A neighbor of George Zimmerman who had perhaps the best view of the struggle between the neighborhood watch volunteer and Trayvon Martin testified at Zimmerman's murder trial Friday that it appeared the unarmed teen was straddling Zimmerman during their confrontation. 
  
 However, Jonathan Good said he did not see anyone's head being slammed into the concrete sidewalk, which Zimmerman has said Martin did to him. Good initially testified that it appeared "there were strikes being thrown, punches being thrown," but during detailed questioning he said he saw only "downward" arm movements being made. 
  
 Zimmerman has claimed that he fatally shot 17-year-old Martin last year in self-defense as the Miami-area teen was banging his head into the concrete sidewalk behind the townhomes in a gated community. 
  
 But under prosecution questioning, Jonathan Good said he never saw anyone being attacked that way during the fight between Zimmerman and Martin. 
  
 "I couldn't see that," Good said moments later while being cross-examined. 
  
 Good, the second person to take the witness stand Friday, said he heard a noise behind his townhome in February 2012, and he saw what looked like a tussle when he stepped out onto his patio to see what was happening. 
  
 He said he yelled, "What's going on? Stop it." 
  
 Good testified he saw a person in black clothing on top of another person with "white or red" clothing. He said he couldn't see faces but it looked like the person on the bottom had lighter skin. Martin was black and was wearing a dark hoodie. Zimmerman identifies as Hispanic and was wearing a red jacket. 
  
 "It looked like there were strikes being thrown, punches being thrown," Good said. 
  
 Later, under cross-examination, he said that it looked like the person on top was straddling the person on bottom in a mixed-martial arts move known as "ground and pound." When defense attorney Mark O'Mara asked him if the person on top was Martin, Good said, "Correct, that's what it looked like." 
  
 Good also said the person on the bottom yelled for help. 
  
 During cross-examination, O'Mara got on his knees to recreate the fighting as he asked Good to walk him through it. 
  
 Good was in the middle of dialing 911 inside his townhome when he heard a gunshot, he said. 
  
 Zimmerman, 29, could get life in prison if convicted of second-degree murder. Zimmerman followed Martin in his truck and called a police dispatch number before he and the teen got into a fight. 
  
 Zimmerman has denied the confrontation had anything to do with race, as Martin's family and their supporters have claimed. 
  
 A second former neighbor of Zimmerman testified after Good. Jonathan Manalo, whose wife had testified earlier in the week, was the first neighbor to step outside and see what happened with his flashlight after he heard a gunshot. He took cellphone photos of a bloodied Zimmerman and Martin's body, and those photos were shown to jurors on Friday. Manalo also described Martin's hands as being under his body. 
  
 Manalo said Zimmerman didn't appear shocked and acted calmly. After police officers arrived and handcuffed Zimmerman, the neighborhood watch volunteer asked Manalo to call his wife and tell her what happened. 
  
 Manalo started to tell Zimmerman's wife that her husband had been involved in a shooting and was being questioned by police when "he cut me off and said, 'Just tell her I shot someone,'" Manalo said. 
  
 Under cross-examination, Manalo said when he asked Zimmerman what happened, the neighborhood watch volunteer told him, "I was defending myself and I shot him." 
  
 "From what you could tell at that moment, that seemed completely true?" asked defense attorney Don West. 
  
 "Yes," Manalo said. 
  
 Before Good testified, a worker at a video surveillance company that maintains cameras at the townhome community took the witness stand. A prosecutor played two videos from surveillance cameras; one showed what looks like a person walking past a window at the complex's clubhouse, and another showed what looks like a light by the complex's mailboxes. 
  
 Greg McKinney said the digital clock on the video is off by 18 minutes, a point O'Mara hammered home by getting McKinney to concede the timing difference was inexact and could be more than 18 minutes. 
  
 Jurors already have been shown some of the state's biggest pieces of evidence, including the 911 call featuring cries for help prosecutors believe came from Martin. 
  
 On Thursday, a friend of Martin who had been on the phone with him when he was shot testified about what she heard during his confrontation with Zimmerman.

Solution:
George Zimmerman's trial has moved on from key witness Rachel Jeantel, with today seeing a handful of people take the stand. The day's standout testimony, largely per the Orlando Sentinel: Zimmerman neighbor John Good, described by the AP as having "perhaps the best view of the struggle," said he heard noise while watching TV on the night Trayvon Martin was killed and stepped outside to investigate. He described seeing a MMA-style scene unfold. In his telling, the two men were "tussling" on the ground, with the person on top in a straddle position and throwing punches "ground and pound" style. He described the person on top as darkly-clad, with the one on the bottom in either red or white, and having lighter skin. Per the evidence, Trayvon was in a dark-colored sweatshirt and Zimmerman was dressed in red that night. When asked if he believed Trayvon was on top, Good replied, "Correct ... that's what it looked like." Neighbor Jonathon Manalo, who was the first one to step outside and took cellphone photos that night that were shown to the jury today, described "blood running down [Zimmerman's] nose from both nostrils and over his lips." He said Zimmerman's demeanor was calm, and said Zimmerman asked him to call his wife. "Just tell her I shot someone," Manalo recounts Zimmerman as saying. He said Zimmerman told him at the time that the shooting was in self-defense. When asked if that "seemed completely true," Manalo replied, "yes." The Sentinel notes that some big names have yet to take the stand. Among them: Trayvon's parents, the medical examiner, and lead Sanford police investigator Christopher Serino.
