CHARLOTTE, N.C. (AP) — A man has been charged with murder in a North Carolina city's 50th homicide of the year.

The Charlotte Observer reports 35-year-old Alton Ulysses Morton Jr. was charged Wednesday in the July 7 death of his wife, 35-year-old Heidi May Morton. Alton Morton was charged after he voluntarily went to Charlotte-Mecklenburg Police headquarters to be interviewed.

Police have not said how Heidi Morton died, but determined in consultation with the Medical Examiner's Office and the District's Attorney Office that she was the victim of a homicide.

It's unclear if Alton Morton has a lawyer.
