"It would mislead the jury and be prejudicial," Guy said. "It doesn't tell us about Trayvon Martin and certainly doesn't tell us what George Zimmerman knew about Trayvon Martin."
However, West said they were relevant.
"It relates to his physical capabilities, his knowledge of fighting," West said.
The effort to get the text messages and cellphone images introduced came after the judge said she would rule Wednesday on whether a defense animation depicting the fatal struggle between Martin and Zimmerman can be played for jurors.
Nelson held an evidence hearing with jurors out of the courtroom. Prosecutors object to allowing the animation, saying it isn't an accurate depiction.
An expert on gunshot wounds also testified that the trajectory of the bullet and gunpowder on Trayvon Martin's body support Zimmerman's account that the teen was on top when the defendant shot and killed Martin.
Dr. Vincent DiMaio, a forensic pathologist, also used photographs of Zimmerman to point out where he appeared to have been struck. His testimony took up a significant portion of the day's hearing. Defense attorneys, who said they may wrap up their case Wednesday, were hoping DiMaio's testimony would help convince jurors of Zimmerman's claims that he shot Martin in self-defense.
DiMaio said the muzzle of Zimmerman's gun was against Martin's clothing and it was anywhere from 2 to 4 inches from Martin's skin.
"This is consistent with Mr. Zimmerman's account that Mr. Martin was over him, leaning forward at the time he was shot," said DiMaio, the former chief medical examiner in San Antonio.
DiMaio testified that lacerations to the back of Zimmerman's head were consistent with it striking a concrete sidewalk. Later, when looking at photos of Zimmerman's injuries taken the night of the shooting, DiMaio identified six separate impacts to Zimmerman's face and head. He said he believed Zimmerman's nose had been broken.
