Overview
- Paramedics responded to a 911 call at the family’s Flint Township home on Nov. 4, 2025, and the boy, identified as Casper O’Brien, was rushed to Hurley Medical Center where he died later that day.
- A forensic autopsy found dilated cardiomyopathy as the cause of death with extreme morbid obesity listed as a contributing factor, reporting Casper was about 4 ft 2 in and weighed 255 pounds.
- Genesee County prosecutors filed charges in late June 2026 accusing Damien and Jessica O’Brien of second-degree murder, torture and multiple counts of child abuse; both were arrested, held without bond and are scheduled for a probable-cause hearing on July 2.
- Court filings allege prolonged neglect including a daily diet of chips and french fries, more than 150 pounds of weight gain in under two years, bed sores from immobility, and a hoarded, unsanitary home despite the family having employment and health insurance.
- Investigators removed the couple’s 5-year-old daughter into protective care and say neither child was enrolled in school nor known to Child Protective Services, a gap that prosecutors say highlights how the case avoided earlier oversight and could prompt local review.
