'I Know I Didn't Shoot a Gun,' Husband Testifies in Utah Murder Trial

— -- A Utah man accused of shooting his wife to death after a night of drinking and watching the TV show "Dexter" was expected back on the stand this morning to face questioning from prosecutors.

Conrad Truman was adamant about his innocence in court Thursday.

“Did you shoot your wife?” a defense attorney asked.

“No,” he said.

“Did you kill your wife?”

“No.”

Truman, 32, is accused of shooting Heidy Truman in the head. Much of the trial has focused on his demeanor that night: from shrieking and speaking incomprehensively in his 911 call, to his behavior around her body, to reports from detectives that he threatened to kill them if they didn’t save his wife.

“I was just confused,” he said in court Thursday. “I didn’t know what was going on.”

Truman also addressed police allegations that he changed his story, previously saying that his wife might have shot herself by accident, or that a gunshot may have come from outside the house. While Truman says he isn’t sure who pulled the trigger, he says it wasn’t him.

“Well, I know I didn’t have a gun. I know I didn’t shoot a gun,” he said.

Truman’s lawyer asked to have the case dismissed Thursday, saying there’s no evidence Truman fired a shot, but the judge refused.

ABC News Chief Legal Affairs Anchor Dan Abrams is intrigued by the decision to have Truman testify.

“The strongest prosecution point is that the medical examiner found that the shooting was not an accident, so if the defense didn’t think he’d be a good witness, it would have been perfectly reasonable not to put him on the stand, and keep pointing out there’s no clear evidence against him,” Abrams said.
