In his own words, George Zimmerman relives his life-or-death struggle with Trayvon Martin:
"He said, 'You're going to die tonight,'" Zimmerman said.
Zimmerman claimed the dispute started after Trayvon Martin circled his car.
"He jumped out of the bushes and he said, 'What the (blank) is your problem homey?' And I said, 'Hey man, I don't have a problem.' And he goes, 'No, now you have a problem.' And he punched me in the nose," Zimmerman said.
Trayvon Martin's parents sat stone-faced as they listened to the grim recording.
Zimmerman was impassive too.
"He grabbed my head and started hitting it into the sidewalk and I said, 'Help me, help me, he's killing me.' I thought he was going for my firearm so I grabbed it immediately and as he banged my head again I just pulled out my firearm and shot him," Zimmerman said in the recording.
The officer also read from a written statement Zimmerman gave that night. He told of Trayvon Martin's last words.
"The suspect sat back, allowing me to sit up, and said, 'You got me,'" Zimmerman said in the statement.
The jury was also shown a video of Zimmerman having his mouth swabbed for a DNA sample. In the video, bandages can be seen from the injuries on the back of his head.
The trial is now in its second week. INSIDE EDITION asked celebrated attorney Jose Baez, who famously won an aquittal for Casey Anthony, to rate the defense and prosecution cases so far.
"I think there's very little evidence that the prosecutor has to work with at this point. I see no way in the world of them getting a second degree murder conviction. This case is clearly the defense's case to lose," he said.
Meanwhile, the defense lawyer who raised eyebrows when he told that knock-knock joke during his opening statement to the jury is making headlines again.
Don West's daughter posted an Instagram photo of herself, her sister and her father enjoying ice cream after court last week. It was captioned, "We beat stupidity celebration cones. #dadkilledit"
West issued a statement saying, "Sometimes we're deeply disappointed by the things our children do. But we love them anyway, and we move on."
