Report Shows Tulsa Toddlers Died From Hyperthermia Complications

The state medical examiner released the exact cause of death of two Tulsa toddlers.

Prosecutors said over the summer, Dustin Dennis fell asleep and his two children climbed into his pickup truck and died in the heat.

The report said three-year-old Ryan and four-year-old Teagan died of complications of hyperthermia.

Second-degree murder charges against Dennis were dismissed due to the McGirt v. Oklahoma Supreme Court case ruling. Both children were Cherokee citizens and died on the Creek Nation’s reservation.

Dennis has been charged in federal court with felony child neglect.
