OLATHE, Kan. (AP) — A man arrested at a suburban Kansas City storage unit with two of his children and his dismembered wife’s remains has been found competent to stand trial after undergoing a mental health evaluation.

The ruling was made Monday during a hearing for Justin Rey in Johnson County, Kansas, where he’s charged with child endangerment.

He isn’t charged in his wife’s killing. Rey says she died after giving birth in October in a Kansas City hotel room. Investigators say he then went to the Lenexa, Kansas, storage unit where he was arrested with the newborn and the couple’s toddler. He was preparing to catch a train. He’s also charged in the death of a California man whose body hasn’t been found.

Rey told The Associated Press he didn’t kill anyone.
