After serving our local community in law enforcement for more than 38 years, Bill Hanley, Chief of the District Attorney’s Office Bureau of Investigations, has announced his retirement effective Friday, November 16, 2018. Chief Hanley has served in the role of Chief since 2005 when he was appointed by District Attorney Gerald T. Shea in 2005.


“During my career, I have had the opportunity to work cases in almost every state. I have worked with and observed many Detective Units and I, without hesitation would put our Bureau of Investigation right at the top in ability, desire, and results,” said Chief Hanley in a memo to staff.  “I continue to marvel at the quality of work that you do and the quality of people I got to work with for so many years.  After 38 years, I realize it is time to leave it to you all to do what you do best.”

Chief Investigator Hanley completes a prestigious 38-year career of serving the residents of San Luis Obispo County.  He began in 1980, being selected as the Top Police Officer by the San Jose Police Academy.  He then served as a San Luis Obispo Police Officer until August of 1985 where he was assigned to major crimes, homicide, robbery, sexual assault, and served a term with the San Luis Obispo County Narcotics Task Force. After being hired as a District Attorney Investigator in 1985, Investigator Hanley distinguished himself as an exceptional investigator who was entrusted with the office’s most notable and difficult cases including: People v. Rex Krebs (1998); People v. Michael Whisenhunt (1995); People v. Harold Ted Cornelius (1998); People v. Dennis Webb (1987); and People v. Mark Weyland et al. (2001).   Chief Hanley has served as a board member and instructor for the California District Attorney Investigator Association.

“I am indebted and very grateful to Chief Hanley for providing excellent leadership and faithful service to this office and to our community. He is a true friend and trusted advisor that I will miss greatly,” said District Attorney Dan Dow.  “Chief Hanley is a quiet and humble public servant who always puts the needs of others ahead of his own. As such, he has earned the high respect and admiration of our entire law enforcement community.  He will be sorely missed.”
