The most recent arrest was No. 37, Robert Tune, who had fled to Georgia. Tune was wanted on a second-degree assault charge and a parole violation. The U.S. Marshals service arrested Tune, he'd been on the run for three years.

It took all year in 2008 to arrest just 33 of the 50 most wanted. This is the 14th year they've done the top 50 round-up.

"We can't do this without the support of the community, their donations and their tips," said Mike Mills, Crime Stoppers Board President.

The criminals range from murderers to sex offenders to white-collar criminals.

They were just some of the 39,000 people in Colorado who have warrants out for their arrests.

"Many of the people that these fugitives units chase are career criminals. And when they're not in jail they're out victimizing additional people," said Division Chief Dave Fisher of the Denver Police Department. "We don't know where they are. But they're dangerous no matter where they may be."

"We need to get all 50 taken care of as quickly as we can; get them incarcerated, get them where they need to be and then begin the next cycle of 50," said Arapahoe County Sheriff Grayson Robinson. "These people all victimized members of our community, up and down the Front Range and across the state."
