DENVER -- Police were fanning out across the Denver metro area hoping to find those on this year's "50 Most Wanted Fugitive Round Up."

Police last year arrested 32 out of 50 on the list. Eighteen agencies from the metro area are taking part in the 14th annual roundup.

By Monday morning, six of 2009's 50 most wanted were in custody. Police had also arrested 39 additional fugitives who are not on this year's 50 most wanted list.

"I think it's been excellent," said Diane Dell, who was helping take tips in the so-called "War Room" on Sunday at Denver Police headquarters. Dell works for the Jefferson County Sheriff's Department.

"A lot of people are calling in. A lot of arrests are being made out there," said Dell.

Police were especially getting an unusually high volume of tips Sunday from Holyoke, where No. 29 on the list Frederick Bauer has recently been spotted. He's wanted for forgery and larceny.

Colorado Bureau of Investigation director Ron Sloan says there are more than 29,000 outstanding felony warrants in Colorado. Those on this year's round up face charges ranging from assault to attempted first-degree murder.

The effort was being coordinated by the Fugitive Location Apprehension Group, which includes Denver police and six other law enforcment agencies.

Denver police said one of their priorities is locating No. 26 on the list, Wayne Weaver. Weaver is charged with scamming at least 100 people while managing the now-defunct Castle Pines Auto Sport dealership in Castle Rock.

His victims said he did not pay off loans on trade-in vehicles, sold nonexistent extended warranties and sold cars that didn't have titles.

Police said they have exhausted all efforts to find Weaver but have come up short. The same can be said for the 49 others on the list.

"People out in the community know these people. They are friends, relatives, former cell mates and classmates," said Chief David Fisher, of Denver police.

Police will be standing by phone lines from 7 a.m. to 7 p.m., waiting to taking any information people may have.

"Any lead could be significant. Anything that is shared with us about a criminal could be the tip that literally breaks the case," said Fisher.

Anyone with information can call Crime Stoppers at 720-913-STOP (7867) and remain anonymous.

Crime Stoppers will be offering cash rewards up to $2,000 for information leading to the arrest and charging of any suspects on the 50 Most Wanted list.
