Firefighters were called to the home on Heathcote Road about 10:30 p.m. that night in response to a reported dispute and fire. Once the fire was out, investigators found 27-year-old Rashawn Cline and her daughter, 1-year-old Dashawn, dead inside.

An autopsy by the Office of the Chief Medical Examiner later ruled the pair’s deaths homicides as a result of the fire.
