The "50 Most Wanted Fugitive Round-Up" was announced Saturday. The operation is coordinated by the Fugitive Location Apprehension Group, commonly referred to as FLAG. The group comprises eight different law enforcement agencies in the Denver metro area.

Police released photos of all 50 of the fugitives they are looking for. .

Police say they’ve been using their resources throughout the year to track these men and women down. Sunday will be dedicated to catching as many as possible. When officers aren’t chasing down leads in these cases, nearly 100 officers will be on the streets handing out warrants.

In last year’s effort, 68 percent of the fugitives were captured.

Rudolfo Gonzalez, 27, is at the top of this year's list and police said he's one of their top priorities.

Police said he shot and killed 21-year-old Teddy Guerra Jr. at a Halloween party in 2005.

His mother and father, Michelle and Teddy Guerra Sr., said they haven't given up hope.

They said they are encouraged to see the man believed to be their son's killer is back on the public's radar.

"To know that much more people are going to see him...maybe we're that much closer to getting him,"said Michelle Guerra.

If you recognize any of the people on the list or know anything about their whereabouts, call Crimestoppers at 720-913-STOP (7867). The call is completely anonymous and you could receive up to a $2,000 reward.
