A Fort Riley soldier was arrested and charged with involuntary manslaughter for a traffic accident that killed a Kansas police officer who was driving home after his shift, according to local law enforcement.

Pvt. Gage Kaiser, 19, was arrested Sept. 10 for a warrant out of Sedgwick County where the March traffic accident occurred, according to the Geary County Sheriff’s Office. The charges against the soldier are involuntary manslaughter while driving under the influence of drugs or alcohol and two counts of aggravated battery.

Kaiser was driving on U.S. Highway 81 in Peck at about 4:19 a.m. March 16 when he ran a stop sign while speeding and hit a vehicle driven by Clearwater Police Officer Scott Hollingsworth, according to the Sumner County Sheriff’s Office, which responded to the accident.

The area is south of Wichita and largely rural with the exception of a nearby casino. Kaiser was leaving the town of Mulvane and traveling to a friend’s house, according to police. Fort Riley is about 120 miles north of Wichita.

Hollingsworth, 26, had just gotten off work and was driving back home to the town of Wellington. He had worked for the department for about a year and is survived by his wife and daughter, according to Clearwater police.

Kaiser, an infantryman, enlisted in the Army in July 2023 from Arkansas City, Kan., and had been assigned to Fort Riley since February, according to the base.

The soldier was in Geary County Detention Center with a $200,000 bond, according to the county’s website. Fort Riley is partially located within Geary County.

Fort Riley has about 15,000 active-duty soldiers assigned to the base. Its largest unit is the 1st Infantry Division.
