SANFORD, Fla. - The defense has not decided yet if George Zimmerman will take the stand in his own defense, but today jurors are hearing his version of events from audio tape of his first interview with police.
State attorney Bernie de la Rionda called Sanford Police Officer Dorris Singleton to the stand late Monday morning.
She's the officer who interviewed Zimmerman at the police station following his deadly encounter with Trayvon Martin.
Zimmerman explains that he was following Martin in his car, because he was walking leisurely in the rain and looked suspicious.
He said he called the 911 non-emergency line and explained what he saw, and the dispatcher told him not to follow the man, and Zimmerman said ok.
He told Officer Singleton that he got out of his car to check the street sign so he could tell the dispatcher where to meet the officer.
"I was walking back through to where my car was and he jumped out from the bushes…" Zimmerman said. "I tried to sit up and yell for help, but he grabbed my head and was hitting it into the sidewalk.
A calm and composed Zimmerman walked through the encounter step-by-step.
"I yelled, 'help me, help me'," he said. "And he said 'you're going to die tonight'."
Zimmerman continued, "I felt his hand going down my side and I thought he was gig for my gun so I got it out and shot him."
The defendant told the officer he thought he was going to die from the repeated bashing of his head into the sidewalk.
After Zimmerman pulled the trigger, he said Martin said, "you got me."
Officer Singleton was the second witness to testify Monday morning. Before her, the state called FBI audio expert, Dr. Hirotaka Nakasone.
Before opening statements, the judge ruled she would now allow expert testimony from witnesses who claim to be able to identify the voice heard screaming for help.
Nakasone testified that the screams are not clear or long enough to identify.
"There's about 2.53 seconds of screaming sort of standing by itself," he said. "That type of voice same is not fit for the purpose of voice comparison."
Before he got off the stand, the state got him to reiterate the best way to identify a voice is by the people who are familiar with it.
That state opened the door for Trayvon Martin's parents who are expected to take the stand very soon and tell the jury that it's their son heard screaming for help.
