SANFORD, Florida - There were some tense moments in the courtroom today in the George Zimmerman murder trial.
The family of Trayvon Martin listened intently as a police officer detailed the final moments of their son's life, trying to save the young man as he lay dying.
Also, a witness for the prosecution testified she saw Zimmerman and Martin fighting. She was an eyewitness who says she saw the deadly confrontation between George Zimmerman and Trayvon Martin on the night the teen was killed.
"It sounded like 'no' or 'uhhh.' I saw what looked as figures and arms, flailing," said Selene Bahadoor.
But the defense tore her apart.
Zimmerman's attorneys claimed she was a Trayvon Martin supporter, that she endorsed a Facebook page demanding "Justice for Trayvon." In the end, attorneys for Zimmerman said it was too dark for the witness to see exactly what happened.
"The first time when you looked out ... the first time you heard a noise, caught your attention, and you couldn't see a thing because it was too dark, is that accurate?," Mark O'Mara asked.
"I couldn't identify figures- who it was out there," she answered.
Earlier in the day, prosecutors showed graphic crime scene photos to jurors of the 17-year-old teenager. More emotional moments came when Trayvon Martin's mother listened as one of the first police officers described trying to breathe life back into her son.
Sgt. Anthony Raimondo from the Sanford Police Department testified that he wasn't able to get a pulse, and that he tried to breathe for the teen.
The state is trying to convince jurors that Zimmerman went too far when the neighborhood watch captain decided to follow Trayvon.
Zimmerman called the cops that night. "Are you following him?" asked a dispatcher.
"Yes," Zimmerman replied.
"OK, we don't need you to do that," the dispatcher said.
This wasn't the first time Zimmerman called police. He called the cops 50 times over eight years.
Prosecutors want the jury to hear those calls where Zimmerman told dispatchers about African-American men in his neighborhood that he calls "suspicious."
The defense doesn't want the calls admitted, but it's up to the judge.
