Columbus police have arrested two brothers in the death of a woman whose body was found on fire last December 23 in a Hilltop alley. 31-year-old Thomas Dortch and 24-year-old Dawan Dortch will be arraigned today in the death of 39-year-old Demeki Walker. Police say they found a large amount of blood and a spent shell casing in her home, indicating she might have been killed there and was burned to destroy evidence.
