Michigan Parents Charged with Murder After 7-Year-Old Son Weighing 255 Pounds Dies from Heart Failure

A Michigan couple has been arrested and charged with murder after their 7-year-old son, who weighed 255 pounds, died from heart disease last year. Authorities say the boy’s death stemmed from years of severe neglect, including poor nutrition, lack of medical care, and living in terrible conditions.

On June 24, Jessica O’Brien, 41, and her husband Damien O’Brien, 40, from Flint Township, were taken into custody. They face second-degree murder charges, torture, and multiple counts of second-degree child abuse related to the death of their son, Casper O’Brien, in November 2025.

Prosecutors allege that Casper had become immobile because his parents did not give him proper food, skipped necessary doctor visits despite having health insurance, failed to encourage any exercise, and kept him in an unsafe, filthy home. Genesee County Prosecutor David Leyton described it as a heartbreaking case of willful neglect that caused the boy immense suffering.

“Their neglect led to their child suffering severe bed sores, various rashes and other physical health disorders including extreme morbid obesity that ultimately led to his early death,” Leyton said.

Casper reportedly lived mostly on potato chips and fries. He had autism, never attended school, and had only seen a doctor once in recent years. In early 2024, he visited his primary care physician and was referred to a specialist, but that appointment never happened. On the morning he passed away, his parents reportedly called their veterinarian about their dog instead of seeking immediate help for their son.

The tragedy unfolded just before 9 a.m. on November 4, 2025, when Jessica called 911 saying Casper wasn’t breathing. Paramedics tried to revive him and rushed him to the hospital, but he was pronounced dead. The medical examiner determined the cause was dilated cardiomyopathy, a serious heart condition, made worse by his extreme obesity.

When police and child protective services investigated the family’s rental home, they found it in appalling shape, filled with trash and filth. There was only one bathroom, and its toilet was broken and overflowing with waste. Casper shared a makeshift bed with his parents and his 5-year-old sister.

In his obituary, Casper was remembered fondly as a bright and loving boy whose joyful spirit touched everyone around him.

The O’Briens are being held in the Genesee County Jail without bond and are scheduled to appear in court again on July 2. Damien’s attorney said it’s too early to comment on the charges, as they have not yet received full details from prosecutors, and plans to defend the case in court rather than in the media.
