Nebraska State Patrol investigators believe Jeremy Koch carried out a tragic murder-suicide that claimed the lives of his wife and two sons on the morning of his eldest child’s high school graduation. Authorities were called to the family’s home near Johnson Lake, Nebraska, where Jeremy, 43, his wife Bailey, 41, and their sons Hudson, 18, and Asher, 16, were found dead from knife wounds.

Family members say Jeremy had struggled with severe mental illness for years, surviving multiple suicide attempts. He and Bailey had even created a Facebook page, Anchoring Hope, to support others facing suicidal thoughts. Just days before the tragedy, Bailey publicly described his ongoing crisis and a March incident in which she woke to him standing over her with a knife, before persuading him to seek help.

Bailey’s parents later expressed anguish and frustration over what they described as failures in the U.S. mental health care system. The loss was made even more devastating by its timing — the same day Hudson was meant to walk across the stage and graduate from high school.

At the graduation ceremony, school officials acknowledged the tragedy, asking the community to hold both grief and pride at once. Autopsies have been ordered for all four family members, and the investigation remains ongoing as the community struggles to process an unimaginable loss.
