(AP) — Omaha police have arrested a homeless man in connection to the death of his ex-girlfriend, whose body was found near a fire.

33-year-old Sonny Delong was booked into jail Friday on suspicion of criminal homicide and first-degree arson in connection to the death of 30-year-old Amanda M. Brown. Court records do not list an attorney.

Firefighters found Brown south of downtown Omaha Tuesday night. Fire crews were dispatched to battle a blaze near railroad tracks in a wooded, brushy area used by homeless people.

Officials say it is unclear how Brown died. An autopsy has been ordered.
