The April 13 fire that killed a DeKalb woman might have been accidental.

The fire is “leaning toward accidental” and the investigation will be left “open for some time, hoping for witnesses or other evidence,” said DeKalb Police Detective Bill Thompson.

The woman killed in the fire, Virginia Tyson, 30, had Downs syndrome and lived with her sister Connie Hawkins at University Village Apartments, 819 Russell Road.

Tyson died from smoke inhalation. Hawkins was at work at the time of the incident, Thompson said.

DeKalb Fire Lt. Stanley Croom said the investigation is “pointing that something happened in the apartment” that started the fire. “It appears possibly she (Tyson) was in the bedroom.”

Fire officials are trying to eliminate all possibilities, Croom said. An electrical engineer will investigate the apartment’s television set today, but Croom said he does not suspect the fire started there.

“Without proof, the fire is considered undetermined,” he said.

Thompson said he interviewed between 15 and 20 people, but there are “no witnesses to place anyone in or around the apartment.”

However, police will interview some witnesses again because new questions have come up during the investigation, he said.
