Captain Chris Arnold, 58, a longtime Wyandotte County Sheriff’s Office officer, was shot and killed inside his childhood home in Kansas City, Kansas, on October 5, 2019. A 28-year department veteran, he had risen to captain, served as a firearms and Taser instructor and K-9 commander, and was remembered by colleagues and family as a gentle giant who loved dogs, hunting and riding his Harley. He is survived by a son, a stepdaughter and two sisters.

Investigators treated the death as a domestic incident and centered the probe on Arnold’s son, 22-year-old Zachary Arnold, who was arrested and charged. Court filings say Zachary, who has documented mental health diagnoses, claimed his father drew a gun during an argument and the weapon discharged during a struggle, fatally wounding Captain Arnold in the face; Zachary called 911 after the shooting. The original charge of second-degree murder was later amended to involuntary manslaughter, and the case proceeded through the courts.

Does anyone in the Kansas City area have information about Captain Arnold or the events leading up to that October 2019 night?
