Florida prosecutors have released several hundred pages of evidence in the killing of Trayvon Martin.
The deadly encounter between George Zimmerman and Trayvon Martin was "ultimately avoidable" if Zimmerman had "remained in his vehicle and awaited the arrival of law enforcement," according to a Sanford police officer's report, the Orlando Sentinel says.
Officer Jonathan Mead took a photo of Zimmerman with his iPhone. The photo showed Zimmerman's bloody nose, which Mead believed was broken.
"I also saw that the back of Zimmerman's head was also bloodied," Mead wrote.
One resident told an investigator he saw a black male in a hooded sweatshirt on top of a white or Hispanic male who was yelling for help. He said the black male was throwing mixed-martial-arts-style punches.
When the witness yelled that he was going to call the police, he heard a "pop," then saw the black male lying on the grass.
The autopsy report, by Volusia County medical examiner, says the fatal bullet went through Trayvon's heart. A diagram showing the fatal gunshot wound was approximately 3/8 inches across. The "stippling," powder burns resulting from a gunshot, was about 2 inches in diameter.
Post-mortem tests also showed that Trayvon's blood and urine contained THC, the active chemical in marijuana, the Orlando paper writes.
