A man who told police he saw Teddy Munet shoot William "Billy" Fallau two years ago testified Monday in state court that Fallau never saw the shot coming.

Munet, 31, is on trial for murder in Fallau’s July 19, 2012, death. Hikers found Fallau’s body in Ka­wai­nui State Park Reserve.

A Honolulu medical examiner testified that Fallau, 29, died from a gunshot that entered the back of his neck, just below the skull, that severed his spinal cord and fractured a vertebra and his jaw, exiting from his right cheek.

Munet’s ex-girlfriend Malia Vidal testified Monday that in the morning before Fallau’s shooting, Munet told her that "he was getting tired of Billy’s s—, that he was going to shoot him."

Then in the evening following Fallau’s death, Vidal said, Munet told her, "Remember what I told you in the car? Well, I did it."

Kaipo Octubre told the jury Monday that the shooting was as swift as it was unexpected. He had gone with Munet and Fallau to the park, where Fallau was smiling and passing around a folding saw he had found on a stump. Octubre, 31, said Munet pulled a gun from his pocket and shot Fallau when Fallau turned his head.

"I was shocked," Octubre testified. "I didn’t know what was going on. I didn’t know what to do."

As he and Munet hiked back to Munet’s car, Octubre said he stayed behind him because he was afraid of being shot, too. In the car, Octubre said, he reclined his front passenger seat in order to keep an eye on Munet, and noticed he had blood on his hands.

He said Munet "went lick his hands, and he said, ‘This is what Billy Fallau’s blood taste like.’" He said Munet called Fallau a fake friend and that he hated Fallau.

In 2013, Munet escaped before a court hearing and was captured nearly 12 hours later.
