George Zimmerman's defense team called forensic pathologist Dr. Vincent Di Maio to the stand on Tuesday.
Di Maio has worked as a pathologist for about 40 years, and he has preformed about 9,000 autopsies and has reviewed more than 20,000 other autopsies conducted by other doctors. The defense asked Di Maio to explain the mechanics of what happens in a gun when a bullet is fired, to explain to the jury how the evidence matches up with Zimmerman's story -- that Martin was standing over him when he was shot by Zimmerman.
