The body of a woman was found set on fire in the basement of a house in Southwest Center City Monday afternoon, police said.

Initial reports indicated that the body of the woman, who remained unidentified around 2:15 p.m., was found by her dog walker around 12:30 p.m., but a police spokeswoman said later that she was unsure who found the body. Police said the woman was found in a house on Naudain Street, just south of Lombard, near 17th. She was pronounced dead at the scene at 12:47 p.m.

Police said they couldn't tell how the woman died, and they were awaiting an autopsy report from the Medical Examiner's Office. The death remains under investigation as suspicious.
