Calls to Wolfinbarger seeking comment today went unanswered. A CSP spokesman would not elaborate on the probe which he says is now closed.

Wolfinbarger joined the Colorado State Patrol in 1995. He became Chief in 2009. He is married and has two children. Lt. Col. Scott Hernandez will serve as acting chief.

Here is the email Chief Wolfinbarger sent out to his staff this afternoon:

Dear members of the Colorado State Patrol,

For the past decade we have seen a dramatic shift in our operations from being a traffic safety organization to a more encompassing public safety agency. Since 2001, when we drafted our first strategic plan, we have seen the creation of Homeland Security and Immigration Enforcement, have expanded and updated our internal mission and vision statements, have brought Leadership in a Police Organization (LPO) education and training to all members of the Patrol, and have voluntarily agreed to meet the standards of CALEA. We are a more progressive and professional agency because of your efforts, and I am extremely proud of each of you.

After countless discussions with my wife and family, I have decided to retire from the Colorado State Patrol, effective January 31, 2013. I am pursuing new challenges and look forward to the next phase of my professional life.

I would like to thank Executive Director Jim Davis for being a great supervisor and an exceptional leader.

I believe everyone who comes to the Patrol, uniform and non-uniform alike, intends to help others, make a difference in the lives of those we assist, and most importantly, to save lives.

I have assigned Lt. Colonel Scott Hernandez to serve as Acting Chief during the interim.

I thank each of you and wish you all the very best of health and prosperity.

Most Respectfully,

Colonel James M. Wolfinbarger
Chief, Colorado State Patrol
