George Zimmerman was telling the truth when he said he shot Trayvon Martin because he thought the teenager would kill him, a police lie detector test found.

A flood of new evidence released Thursday by Zimmerman’s attorney included video and audio of Zimmerman’s various police interviews and a recording of a voice stress test he took on Feb. 27 — almost exactly 24 hours after the shooting.

“Were you in fear for your life when you shot the guy?” Sanford Police Investigator William Ervin asked.

Zimmerman replied without hesitation: “Yes.”

As part of the test, Zimmerman had been told in advance that he would be asked that. He was so eager to answer the question that he interrupted Ervin’s first attempt to ask, and had to be admonished to let the cop finish before replying.

The scene was bizarre: Zimmerman was made to sit facing a blank wall in a Sanford Police interview room while the cop asking questions sat behind him fiddling with a laptop that monitored the sound of Zimmerman’s voice.

Two days later, in an audiotaped interview also released Thursday, Sanford Police Investigator Chris Serino tells Zimmerman the test found no deception.

“Obviously, you passed a lie detector test,” Serino said Feb. 29.
