Colt Gray, who was 14 at the time of the shooting, has pleaded not guilty to a raft of charges. <\/p>\n Prosecutors said Colin Gray gave his son access to a gun and ammunition despite knowing that his mental health had deteriorated.<\/p>\n A look at other cases:<\/p>\n In Wisconsin, Jeffrey Rupnow is charged<\/a> with intentionally giving a dangerous weapon to a person under 18 causing death. In 2024, his daughter, Natalie Rupnow, 15, killed a student and a teacher at Abundant Life Christian School in Madison and then killed herself.<\/p>\n Prosecutors said Rupnow told investigators that his daughter was struggling to cope with her parents\u2019 divorce and that he bought her guns as a way to connect with her.<\/p>\n Rupnow’s attorney has argued that he acted reasonably. Natalie had passed a gun safety course, and Rupnow took the extra step of keeping guns in a safe, Lisa Goldman said at a hearing in July 2025.<\/p>\n Jennifer and James Crumbley were the first U.S. parents held criminally responsible for a mass school shooting committed by a child<\/a>. They are serving 10-year prison terms<\/a> for involuntary manslaughter.<\/p>\n Their son, Ethan Crumbley, killed four students and wounded others at Michigan’s Oxford High School in 2021. The school revealed his violent drawings to the Crumbleys a few hours before the shooting, but they declined to take him home. No one checked his heavy backpack for a gun.<\/p>\n The Crumbleys were not aware of their son’s plans, but they had given a gun as a gift a few days earlier. Prosecutors said Ethan’s actions were foreseeable and that the Crumbleys had failed to prevent the violence.<\/p>\n Robert Crimo Jr. pleaded guilty to misdemeanors<\/a> for endorsing his son’s Illinois gun permit in 2019 despite knowing that Robert Crimo III had expressed suicidal thoughts. <\/p>\n Three years later, Crimo III killed seven people<\/a> at a Fourth of July parade in Highland Park, a suburb north of Chicago.<\/p>\n \u201cHe was criminally reckless the moment he submitted that affidavit,\u201d prosecutor Eric Rinehart said of the father.<\/p>\n Crimo Jr. was sentenced to 60 days in jail. His son is serving a life prison sentence<\/a> after pleading guilty in March to murder. <\/p>\n Deja Taylor was prosecuted in state and federal court after her 6-year-old son took her gun to school and wounded a teacher<\/a> in a classroom full of students in Newport News, Virginia, in 2023.<\/p>\n Taylor was sentenced to 21 months in federal prison<\/a> for a drug-related crime connected to possessing a gun. Separately, she was sentenced to two years in state prison for child neglect.<\/a><\/p>\n \u201cThat is my son, so I am, as a parent, obviously willing to take responsibility for him because he can\u2019t take responsibility for himself,\u201d Taylor told \u201cGood Morning America\u201d in 2023.<\/p>\n The teacher, Abigail Zwerner, told a judge she wasn’t sure \u201cwhether it would be my final moment on Earth.\u201d <\/p>\n<\/div>\n
