An American couple have been charged with murder following the death of their 7-year-old son who weighed a staggering 17 stone (113kg). Damien and Jessica O'Brien are accused of inflicting severe physical harm on their reportedly immobile son, according to a complaint lodged by the Genesee county prosecutor's office.

Emergency services were alerted to young Casper's plight after receiving a distressing 911 call about a child not breathing at a residence in Flint township, Michigan, on November 4, 2025. The boy tragically passed away after being rushed to hospital.

The couple were subsequently charged with second degree murder and multiple counts of child abuse. If found guilty, the O'Briens could be looking at life behind bars. "It was reported that the decedent's diet was potato chips and fries because of texture issues," deputy medical examiner John A Bechinski wrote in a forensic autopsy report, according to Michigan news outlet MLive.
