George Zimmerman failed to identify himself twice and missed opportunities to defuse a confrontation with Trayvon Martin, a detective says in a newly released report.
Zimmerman, a neighborhood watch volunteer, is charged with second-degree murder in the February 26 shooting death of Martin, 17, in Sanford, Florida.
The report, which Florida prosecutors released Tuesday, includes a video of Zimmerman showing injuries he said he suffered in the altercation with Martin.
Zimmerman, 28, told police he shot the teen in self-defense, but many feel he racially profiled Martin and ignored a 911 dispatcher's advice not to follow him.
Among the documents released was a report from a police officer who conducted computerized voice stress analysis tests on Zimmerman following the incident.
"Mr. Zimmerman was subjected to two exams, and was found to be classified as No Deception Indicated," the report said.
Also released was an unredacted capias request, a request that someone be taken into custody, prepared by the lead police investigator in the case.
Christopher Serino wrote in the report:
"Investigative findings show that (Zimmerman) had at least two opportunities to speak with (Martin) in order to defuse the circumstances surrounding their encounter."
"On at least two occasions (Zimmerman) failed to identify himself as a concerned resident or a neighborhood watch volunteer."
