OKLAHOMA CITY - A police report uncovered from June of 2013 claims to give a glimpse into the mental state of Christian Costello.
According to the report, the 26-year-old was convinced he was being followed in the years before he allegedly stabbed his father, Labor Commissioner Mark Costello, to death outside an Oklahoma City Braums.
Christian claimed he and his girlfriend found “GPS tracking devices in their car” and said their phones had been hacked.
Police will not tell us who Christian was accusing of spying, but in the report he describes the suspect as “controlling” and claims they had been “caught previously doing the same type of things to his sister.”
Christian also told police that the person “always wants to be in charge and know what’s going on” and stopped giving him funds because that person was upset with who he (Christian) was dating.
Family members say Christian has a history of mental illness and that they tried to help him.
Police say they are still looking into why he allegedly stabbed his father to death.
