CHICAGO (STMW) – Investigators are trying to determine what caused a fire that damaged the Calumet Heights home of Cook County Clerk of the Circuit Court Dorothy Brown Friday night on the South Side.

Brown and her husband were returning home from an evening out when they saw the blaze and called the fire department, Brown’s spokeswoman Enza Raineri said.

Firefighters responded about 9:30 p.m. to the blaze in the 8800 block of South Constance Avenue, according to Fire Media Affairs.

The fire was in the basement and first floor and caused a partial floor collapse, according to the fire department. Nobody was injured.

Brown has two dogs, who also managed to escape unharmed, Raineri said.

The cause of the fire remains under investigation Friday night.
