A Wichita father, Brijin M. McCullough, has been sentenced to 36 1/2 years in prison for the fentanyl poisoning death of his one-year-old son, Kaiden, on Halloween 2023. McCullough pleaded guilty to second-degree reckless murder and other drug-related charges. Two days earlier, the child's mother, Wilma Faye Presley, received a 20-year sentence for distributing a controlled substance causing death and aggravated endangering a child. Prosecutors revealed that Kaiden was exposed to lethal levels of fentanyl while in McCullough's car during a drug transaction. Both parents continued drug-related activities even after their child's death, including coordinating from jail. The tragic incident occurred when Kaiden became unresponsive during a Walmart shopping trip, and he was later pronounced dead at a Wichita hospital.
