JEFFERSON CITY -- A mid-Missouri murder case is getting some national attention this weekend.

The popular TV show "America's Most Wanted," which normally tries to track down criminals, will instead offer a one hour special Saturday on Dale Helmig who was convicted of murdering his mother in 1995.

The show's producers say Helmig deserves a new trial.

"There's not one solid fact, nothing that ties my brother to this crime," said Richard Helmig, Dale's brother. "There's nothing."

Richard Helmig is adamant that Dale didn't kill their mother in 1993. "Absolutely not," he said. "They had a wonderful relationship."

During the Great Flood of '93, their mother, Norma Helmig, disappeared. Her body was found along the Osage River. Richard says then-prosecutor Kenny Hulshof zeroed in on his brother.

"Instead of letting the evidence lead them to the perpetrator," said Helmig. "They went out and found out everything they could use against" Dale.

Richard says there were a number of missteps at trial, including a lack of evidence.

"They twisted the facts," he said. "They lied, flat out lied on the witness stand. They manipulated evidence. They did everything they could."

Dale Helmig has been behind bars for almost 14 years. He's serving a life sentence without the possibility of parole. But his case is getting a second look - thanks to "America's Most Wanted."

"I think there are lots of people that realize there are innocent people in jail," said the show's host, John Walsh. "That the criminal justice system is the criminal injustice system."

In a video preview on the show's Web site, Walsh says there were "prosecutorial missteps" during the trial. We were unable to contact Hulshof but he has said previously that he stands by the jury's decision.

Richard Helmig noted that the conviction of Joshua Kezer - another case prosecuted by Hulshof - was recently set aside and that gives the family hope.

"America's Most Wanted" will devote an entire show, a full hour, to the Helmig story Sat. May 30 at 8 p.m.

Richard hopes the publicity will prompt authorities to give his brother's case a second look.

"We're asking for a new trial," he said. "That's all we're asking for. Just a new trial. Let the facts come out and I guarantee you that the outcome will be different."
