“This was completely unexpected. ”
Those were the words Jessica O’Brien said after investigators walked her through the extent of her son’s injuries. By then, seven-year-old Casper O’Brien was already dead. He died on the morning of November 4th, 2025, in a rented three-bedroom house on Donya Street in Flint Township, Michigan.
That morning, his parents called their veterinarian because they believed one of their dogs had suffered a stroke. Shortly after, Jessica called 911 to report that her son was unresponsive and not breathing. Casper’s uncle found him with blue lips and foam in his mouth. He cleared the boy’s airway and started chest compressions.
He was still performing CPR when paramedics arrived. The first responders couldn’t move freely inside the home. The floor was buried under trash on every surface. There was no working toilet, and human waste had accumulated throughout the house.
It was infested with bugs. Casper was found in a makeshift bed shared by family members. He was wearing a soiled diaper. He was extremely obese, visibly dirty, and unable to move on his own.
He was four feet two inches tall and weighed 255 pounds. His body mass index was 71. 7. For a boy his age, the typical BMI is around 16.
At the emergency room, doctors found some of the worst open sores and rashes they had ever seen. The wounds were infected and swollen, covering his back, legs, and thighs. His hair had been unwashed and unbrushed for so long it was matted and smelled strongly. His fingernails hadn’t been cut in a long time.
Casper was pronounced dead at 9:32 a. m. at Hurley Medical Center. The medical examiner ruled the cause of death as dilated cardiomyopathy, a disease in which the heart’s ventricles become thin and stretched, leaving the heart unable to pump blood properly.
The examiner listed morbid obesity as a contributing cause. The attending physician, a specialist in child abuse and neglect, documented that neglect and abuse were also contributing factors. Two years earlier, in February of 2024, Casper had been brought to an urgent care clinic. That was the only documented medical visit of his life.
He was diagnosed with an acute cough, throat congestion, and metabolic disease. He weighed a little over 104 pounds at the time. The doctor referred him to a pediatric endocrinologist, but he never went. Jessica later said she had a traumatic history of being sexually assaulted by a doctor, and that was why she avoided taking herself or her children to medical appointments.
She didn’t want to subject them to the same experience. Between that single clinic visit and the day he died, Casper gained roughly 150 pounds in less than two years. Jessica told investigators she spent about 12 hours a day lying in bed. She believed Casper had avoidant restrictive food intake disorder, a condition where a person restricts what they eat based on sensory properties like texture, smell, or appearance.
According to Jessica, Casper didn’t like getting wet, which she claimed made bathing him difficult. She said she used baby wipes on him two to three times a week. She estimated his last actual bath had been about six months before his death. Casper’s daily diet reportedly included a large bag of potato chips, a large order of french fries, apple juice, and sparkling carbonated water.
There was no indication he was given any opportunity to exercise. He was autistic and didn’t speak. He had never been enrolled in school. Neither had his five-year-old sister.
When officers found Casper’s sister, she was outside the house, unclothed, dirty, with knots in her hair. She also weighed 130 pounds and was morbidly obese. One prosecutor described her as being like a feral child. She was immediately taken into the care of Child Protective Services.
Jessica later told investigators she suspected the girl was nearly blind in one eye, but she had never taken her for an examination. Child Protective Services had no prior record of either child. As prosecutor David Layton put it, “None of these kids even existed in the eyes of the government. CPS had never been out there.
Nobody knew about these kids. They had not been to school. ”
He also pointed out something that stuck with many people: the call to the veterinarian. “They had called the veterinarian about one of their pets.
They knew what to do for the dog, but they didn’t do it for their own child. ”
The home’s landlord had grown concerned as the property fell into visible disrepair, but the couple wouldn’t let them inside. They simply left the rent on the front porch. Casper’s uncle told investigators he had repeatedly warned Damian and Jessica that CPS would get involved if they didn’t clean the house.
When asked why he never called CPS himself, he said Damian was the only family he had left, and he was living in their house after all. During the investigation, both parents spoke to police about their mental health. Damian, a 40-year-old cloud engineer for Delta Dental, told investigators he had a drinking problem but had been sober for three months due to his diabetes. Jessica, 41, told investigators separately that his drinking had gotten really, really bad and that they weren’t communicating.
Damian and Jessica O’Brien were charged on June 23rd, 2026, and arrested the following day. They were held without bond at the Genesee County Jail. Each of them faced five counts: one count of second-degree murder, one count of torture, and three counts of second-degree child abuse, one of which covered the neglect of Casper’s little sister. At the probable cause hearing on July 2nd, 2026, neither parent appeared in court.
The defense asked for more time to review discovery, noting the case involved more than 400 pages of medical records. Attorney Elias Feneuse, representing Damian, told the court, “We’re still reviewing discovery here, Judge, but I don’t see murder, let alone torture. ”
Judge Mark McCabe postponed the hearing and ordered both parents to undergo competency and criminal responsibility evaluations. Both defense attorneys filed motions for reasonable bond, arguing that neither parent posed a danger to the community.
Judge McCabe denied both motions. After the denial, Feneuse said, “This is a tragic case. It shouldn’t be made more tragic by him having to grieve the loss of his son while in jail. ”
Under Michigan law, second-degree murder and torture each carry a maximum sentence of life in prison.
Legal analyst Dave Aronberg argued that charging the parents with second-degree murder rather than manslaughter was the right call. He described the case as a slow, agonizing, years-long process of willful and wanton cruelty, and pointed out that with Damian employed and having excellent health insurance, poverty was not an excuse. Second-degree murder doesn’t require proof of premeditation, but it does require proving willful and wanton misconduct, essentially that the defendants acted or failed to act in a way where the most obvious consequence would be great bodily harm or death. Prosecutors argued this wasn’t a single mishandled medical emergency, but a series of choices made over the course of years.
The parents understood, or should have understood, what the final result was likely to be. Casper’s funeral was held on Saturday, November 15th, 2025. His obituary asked that in lieu of flowers, contributions be made to the family in the care of Damian O’Brien. That obituary was written in November of 2025, months before any charges were filed.
The only known recent photograph of Casper was provided to the media after his death. It was clearly edited heavily, and some people suggested it might be an AI-generated rendering, although that couldn’t be confirmed. Looking at Jessica’s social media, there wasn’t a picture of Casper since he was four or five years old. That means it’s possible no pictures of Casper were taken for the last three years of his life.
On a positive note, prosecutor Layton confirmed that Casper’s little sister is in temporary foster care and is doing quite well, despite everything she went through and witnessed. As for Damian and Jessica O’Brien, they have not yet gone to trial and are considered innocent until proven guilty in a court of law. The next court date is set, and no trial date has been scheduled yet.
