Jurors on Tuesday will again hear from the lead detective who investigated the 2012 fatal shooting of Trayvon Martin, after listening to other defense witnesses and taped testimonies from George Zimmerman on Monday.
Prosecutors played four taped testimonies on Monday in which Zimmerman, 29, gives a general account of what happened on the night of Feb. 26, 2012, when he shot and killed 17-year-old Martin. The prosecutors argued that although Zimmerman's story line remains the same overall in each account, some of the details changed.
The former neighborhood watch volunteer has been charged with second-degree murder for fatally shooting the teenager last year, to which he has pleaded not guilty. He does not deny shooting Martin, but says he acted in self-defense.
Zimmerman maintained in each account that he found Martin suspicious because he was standing in the yard of a home that had recently been robbed. In one recorded testimony, Zimmerman said he called police and followed Martin on foot, meeting him face to face when he was heading back toward his truck. But he originally told police that he was not following Martin, and that he had gotten out of his truck because he was trying to find a street sign.
Zimmerman's story also varied when he described an exchange he had with the teenager before the fight started. According to an initial account to investigators, Zimmerman said Martin approached him, saying, "What the f--- is your problem, homey?"
But the day after the shooting, Zimmerman said Martin simply said, "You got a problem?" to which he replied, "No, I don't have a problem," according to the Orlando Sentinel.
According to Zimmerman's account, the teenager said, "You've got a problem now," before he began beating him.
Zimmerman said that as he saw Martin reach for Zimmerman's gun, he grabbed the teenager's hand, pulled out the gun and fired one shot.
In a subsequent interview, Zimmerman again changed the details of what happened when he said, "I wasn't following. I was just going in the same direction," the Orlando Sentinel reported.
Chris Serino, the case's lead detective who will again testify on Tuesday, told Zimmerman, "That's following, man."
Serino, along with another investigator, Doris Singleton, recounted their investigations to jurors on Monday.
Serino told the jury on Monday that he did not believe that Martin had knocked Zimmerman to the ground with one blow, nor that he punched Zimmerman 25 to 30 times because Zimmerman did not appear to be hurt that badly.
However, Serino said he believed Zimmerman, because when he tried to fool him by saying Martin had videotaped the encounter, Zimmerman said, "Thank God."
Singleton also testified on Monday, saying that in her initial interview with Zimmerman the night of the shooting, he was shocked when he learned that Martin had died.
"He's dead?!" Singleton recalled Zimmerman saying that night.
Earlier, prosecutors also called an FBI audio expert to the stand. Hirotaka Nakasone said there was no way to tell whose voice is heard screaming in the background of the 911 calls during the encounter, according to Central Florida News.
Zimmerman's father has said it was his son calling for help, while Martin's family maintains it was the teenager screaming.
