LAMAR, Mo. — A former Lamar police officer apparently shot his estranged wife and her mother before killing himself early Tuesday morning in a rural area near the Lamar Municipal Airport.
The Missouri State Highway Patrol said Landon Ison, 32, apparently shot and killed his wife, Dana I. Ison, 33, and wounded his mother-in-law, Cheryl J. Thompson, 67, at their home at 91 SW Fifth Lane, sometime early Tuesday morning.
Highway Patrol Sgt. Mike Watson said the first call to 9-1-1 came in about 1 a.m. from a neighbor’s house just south of the residence.
“Lamar PD, the Barton County Sheriff’s Office and medical personnel responded and found Cheryl Thompson in the entryway of the home,” Watson said. “She had apparently tried to call 9-1-1 from the home, but the connection had failed, so she walked to the neighbor’s home and they called 9-1-1 and were able to identify the situation.”
Watson said Thompson was then able to walk back to her daughter’s home, where she was found.
Watson said investigators told him Thompson’s injuries were “life-threatening,” and she was being treated at Cox South Hospital in Springfield. He did not know her condition as of late Tuesday.
Dana Ison was found dead of a gunshot wound inside the home. She was pronounced dead at the scene by Barton County Coroner C. Tucker Joustra.
“Based on information at the scene, officers identified a suspect, Landon Ison, and attempted to locate him,” Watson said. “At 2:30 a.m. (Tuesday) they located him in a field in a rural area. He was dead of a self-inflicted gunshot wound.”
Watson said he was found in his blue Ford Explorer.
The couple’s two boys, both minors, were in the home at the time of the shooting, but they were not hurt, Watson said.
Lamar Police Chief Ron Hager said Landon Ison worked for the Lamar Police Department from January 2003 until this past August when he resigned suddenly without giving a reason.
Barton County Sheriff Mitchell Shaw said he called in the Missouri State Highway Patrol to investigate because of the close relationship Ison had with Sheriff’s employees.
Watson said investigators believe two different guns were used in the shootings. He said the rifle Ison used to shoot himself was apparently not the gun he used to shoot his estranged wife and her mother.
He said Landon Ison and Dana Ison had been separated since Oct. 1 and Landon Ison had been living at a residence in Lamar.
Watson said the investigation was continuing as officials worked to determine a timeline of what exactly happened and where everyone was prior to the shooting.
