In a quiet, rural home near Blue Springs, Nebraska, the life of 40-year-old Caucasian female Brooke Nicole Koch came to a tragic end on the morning of April 6, 2021. Gage County deputies responded to a 911 call and discovered a grim scene inside the residence. Koch was found deceased, the victim of a fatal shooting. Alongside her was the body of 49-year-old Jason Arnold, who died from what authorities believe was a self-inflicted gunshot wound. The Nebraska State Patrol's preliminary investigation led them to conclude that Arnold shot and killed Koch before turning the shotgun on himself in a murder-suicide.

The day of the tragic discovery was the same day Arnold was scheduled to appear in Gage County Court for violating a protection order that Koch had obtained against him. This was not the first instance of trouble between the two. Court documents from an August 2020 petition for a restraining order detailed a pattern of abusive and threatening behavior from Arnold. Koch had ended their relationship due to his verbal abuse and alleged meth use. In the petition, she recounted how he had stalked her home, flipped a table, and acted as if he were going to throw a chair at her. He had previously been arrested on domestic charges and had reportedly threatened her, saying, "I'm going to blow you away," and on another occasion, "A little bang bang, to you."

In the wake of the murder-suicide, it was revealed that Arnold had a history of threatening Koch with violence. He had been enrolled in a diversion program after criminal offenses were filed against him. He was later arrested and charged a second time but was released after posting bond. A tort claim for $25 million was filed against the Gage County Attorney in April 2022, alleging gross negligence for failing to refile charges against Arnold after he was terminated from the diversion program. The claim argued that this failure contributed to Koch's wrongful death. There was no arrest in the case as the sole suspect, Jason Arnold, died at the scene.
