SALINA, Kan. (AP) — A retired Salina police lieutenant has announced plans to walk across Kansas to raise money for cancer research.

The Salina Journal reports  that retired police Lt. Dean Bonawitz, who is also a cancer survivor, plans to walk west-to-east across Kansas on a “Cops for a Cure” journey. The 400-mile solo walk will begin May 12 at the Kansas-Colorado border and is expected to end June 12.

Bonawitz will be walking along U.S. 36, covering 15 miles a day. Saline County Sheriff Glen Kochanowski has pledged to donate $1 a mile.

The 69-year-old Bonawitz is a prostate cancer survivor. His wife, Nancy Bonawitz, a breast cancer survivor, is driving the support vehicle this year.
