James and Jennifer Crumbley, the parents of the teenage gunman who shot and killed four students in a 2021 school shooting at Oxford High School in Michigan, were sentenced to 10 to 15 years in prison after being convicted of manslaughter in separate trials.
Judge Cheryl Matthews noted that the Crumbleys could have acted to prevent the tragic shooting.
"Opportunity knocked over and over again, louder and louder, and was ignored," Judge Cheryl Matthews said. "No one answered, and these two people should have, and sure didn't."
She added, "These convictions confirm repeated acts or lack of acts that could have halted an oncoming runaway train."
James and Jennifer each addressed the court and apologized for the pain and suffering their son caused.
"I sit here today to express my deepest sorrows for the families of Hana, Tate, Madisyn, Justin, and to all those affected on November 30, 2021," Jennifer said.
"I will be in my own internal prison for the rest of my life," she added.
"I want to say I can't imagine the pain and agony ... for the families that have lost their children and what they are experiencing and what they are going through. As a parent, our biggest fear is losing our child or our children, and to lose a child is unimaginable. My heart is really broken for everybody involved," James said.
"I really want the families of Madisyn Baldwin, Hana St Juliana, Tate Myre, and Justin Shilling to know how truly sorry I am and how devastated I was when I heard what happened to them," he added.
Judge Matthews said the Crumblys will receive credit for 858 days already served.
