DENVER — A man once charged with murder in the presumed death of his missing wife denied having anything to do with her disappearance in an interview broadcast on Monday.

In the interview with “Good Morning America,” Barry Morphew said authorities in Colorado have been wrong to focus on him as the person responsible for the death of Suzanne Morphew, who disappeared three years ago on Mother’s Day.

“They’ve got tunnel vision and they looked at one person, and they’ve got too much pride to say they’re wrong and look somewhere else,” he said, sitting between his adult daughters, who have defended him.

Prosecutors dropped charges against Morphew last year just as he was about to go on trial after a judge barred them from calling most of their key witnesses for repeatedly failing to follow rules for turning over evidence in his favor. That included DNA evidence linked to sexual assault cases in other states that raised the possibility of a different person being involved.

At the time, prosecutors said they wanted more time to find Suzanne Morphew’s body. They have said he is still a suspect as recently as last month, when Morphew’s lawyers announced they had filed a complaint asking that the prosecutors be disciplined for allegedly intentionally withholding evidence in effort to convict him.

This month, Morphew filed a $15 million lawsuit against prosecutors and investigators, accusing them of violating his constitutional rights.

District Attorney Linda Stanley did not immediately return a phone call or email seeking comment.

The charges against Morphew were dismissed without prejudice, so prosecutors can still decide to bring charges against him again. Morphew said he realizes that’s a possibility, since he said he was innocent the first time he was arrested.

“But I don’t have anything to worry about. I’ve done nothing wrong,” Morphew said.
