District Attorney Ken Buck

Since 2004
, Weld County District Attorney Kenneth R. Buck and his office have made great strides toward making Weld County a safer place to live and work.


The problems facing today’s youth are one of the areas Ken has focused on as district attorney. Early in his term, Ken collaborated with several community groups to develop the Juvenile Ground breaking for the JAC (juvenile assessment center) Assessment Center (JAC) which encourages a multi-disciplinary approach to address issues such as delinquency and truancy. To date, the JAC has helped more than 1,100 Weld County kids and their families. Two other programs, which are run through the district attorney’s office, have also had a positive impact on Weld County youth: the Truancy Diversion program and the Juvenile Diversion Program.

In an effort to relieve overcrowding at the jail and to better help those with mental health and/or substance abuse issues, ICAPP (In-Custody Alternative Placement Program) was formed to serve those defendants who would benefit from treatment rather than jail time. Initiated in Weld County by Ken, this program incorporates the valuable services and input of many county law enforcement and treatment agencies. Although this program is still in its infancy, it has already had a positive life-changing impact for those who have completed it.

Recently the gang task force was awarded a $235,000 grant from the Federal Government to continue its work to reduce gang crime in Weld County. The D.U.I. Task Force works toward reducing drunk driving in the county and is supported solely by grants. The White Collar Crime Task Force, a unique partnership between the district attorney’s office and area banks, is responsible for prosecuting white-collar crime cases which have resulted in almost   $1 million in restitution.

Under Ken’s direction, the district attorney’s office has also reached out to the community. Attorneys sit on a variety of boards including A Woman’s Place, A Kid’s PlaceKen speaking at Evans senior lunch, SASI and Island Grove Regional Treatment Center. The office as a whole participates in numerous community activities throughout the year. Employees of the office have served more than 300 meals at the Guadalupe Shelter and have organized three annual blood drives. This office has also provided more than 750 hours of presentations to more than 16,000 residents of Weld County.


The job of any district attorney is to effectively handle criminal cases for the people of the county. From day one, Ken was determined to do his part to reduce crime in Weld County through tough prosecution and harsh sentences. In eight years, his office has received 17 life without parole sentences—several of which were imposed on dangerous gang members.

Ken's office has aggressively tried and won numerous first and second degree murder cases, sexual assault cases, child abuse cases, vehicular homicide cases, drugs, white collar  and habitual criminal cases. The cumulative sentences for the worst of these cases add up to more than 6,237 years in prison. Dangerous criminals are being taken off of Weld County streets and that is good news.


Ken Buck was elected District Attorney by the citizens of Weld County in November 2004. A veteran prosecutor, Ken gained substantial experience prosecuting violent criminals, fraud and high-profile cases during his tenure with the U.S. Attorney’s Office in Denver, Colorado. He served as Chief of the Criminal Division while a part of that office.

In 1981, Ken earned his undergraduate degree in Politics from Princeton University. He received his Juris Doctorate in 1985 from the University of Wyoming School of Law.

Congressman Dick Cheney hired Ken to work on the Iran-Contra Investigation in 1986. He began working as a prosecutor with the U.S. Department of Justice in Washington D.C. in 1987. Ken then joined the Colorado U.S. Attorney’s Office in 1990. Throughout his years in Colorado, Ken has served as an instructor at the University of Denver Law School and for the National Institute of Trial Advocacy.

Ken has life-long ties to Weld County, and has been active in our local community for many years, including associations with North Range Behavioral Health, A Woman’s Place and the Restorative Justice Coalition.
