Phoenix police say two officers' decision to pay for a troubled man's restaurant tab led to his being arrested in his roommate's stabbing death.

Sgt. Tommy Thompson says the officers went to a restaurant Wednesday after a man would not pay his bill. The officers concluded the man had some type of mental health issue, so they paid for his meal and took him to a behavioral health facility rather than take him to jail.

While at the facility, the man allegedly told staff he'd done something bad to his roommate. Police were contacted and went to his apartment, where they found the body of 29-year-old Steven Horkovy.

Police say 23-year-old Mykel Cantrel Cooper has been arrested on suspicion of first-degree murder. It's not clear whether he has an attorney.
