It is with a heavy heart that we have to report that the former Chief of the Civil Division, Chris R. VanSchaik, passed away at his home on Sunday, November 3, 2019.  

Chris was born in Dayton on February 9, 1941, to the late Chris and Vera VanSchaik.  Chris graduated from Chaminade High School and the University of Dayton before attending the University of Cincinnati Law School. 

Chris was appointed as an Assistant Montgomery County Prosecuting Attorney on November 9, 1970, and in 1979 he was promoted to the position of Chief of the Civil Division of the office.  He served in that position until his retirement in December 2004.  Chris was the legal advisor and attorney for the Montgomery County Board of Commissioners and attended the commission meetings for over two decades. 

Prosecuting Attorney Mat Heck said, "Chris VanSchaik displayed the utmost integrity and dedication to a life of public service.  He was a most valued employee and was a well-respected expert and speaker on county and municipal law throughout Ohio.  Chris had a great sense of humor and will be sadly missed by all of us who had the good fortune of working and spending time with him at and outside of work."

Former Prosecuting Attorney Lee C. Falke added, "I hired Chris in 1970 right out of law school.  It was an excellent choice, as he was a hard-working and smart lawyer who eventually was promoted to the Chief of the Civil Division. In addition to his ability as an attorney and assistant prosecuting attorney, he always had a joke to liven up the day.  He is missed."

The Ohio Crisis Response Team awarded the Outstanding Community Leadership Award to Ms. Sandy Hunt, the DIrector of the Victim/Witness Division.  The award was given to recognize her efforts in facilitating and expeditiing a supportive response during "a time of community-wide crisis," the Oregon District shooting.
