The Kansas Bureau of Investigation is investigating the death of a man believed to have shot himself while authorities were conducting a search warrant at his residence.

 Yesterday, shortly after 11 a.m., the Marion County Sheriff’s Office requested KBI assistance to conduct the investigation. KBI agents responded to the scene.

 Preliminary information indicates that yesterday morning around 10:35 a.m., the Marion County Sheriff’s Office and the Marion Police Department began conducting a search warrant at 341 S. 4th St. in Marion, Kansas. The suspect, 65-year-old Charles Park, was present while deputies and officers were searching his residence related to a felony investigation.

 During the search and interview, Park reached for a shotgun that was hidden inside the house. He then shot himself in front of the officers. The self-inflicted gunshot wound was fatal. The coroner pronounced Park deceased at the scene.

 No law enforcement officers discharged their weapons during the incident, and no law enforcement officers were injured.
