A 4-year-old Utah boy reported missing Sunday morning was found dead in his home later in the day.

The Hurricane City Police Department reported that Kache Wallis was last seen Saturday evening when he was tucked into bed wearing white Teenage Mutant Ninja Turtle pajamas but was missing when the family awoke in the morning. At the time, they suggested the boy might be with his non-custodial, biological mother.

But just four hours later, police reported that the boy was “located deceased in the home” without providing any further details.

The department said the death was being investigated by police and the Medical Examiner’s Office.

“”Our thoughts & prayers go to the family of Kache Wallis at this difficult time,” police said in a statement.
