UPDATE | No foul play suspected for two found dead in South Side home

YOUNGSTOWN — A mother and daughter were found dead this afternoon in their Mercer Street home, and authorities believe they died of natural causes.

The mother, 86, and daughter, 58, both had health problems and were under doctor’s care, police said. The family recently had a new furnace installed, but scans run by the city fire department found no measurable carbon-monoxide readings.

Toxicology tests will be run, police said. The mother’s son, who had last spoken to the women Thursday, came to check on his mother and sister Saturday when he hadn’t heard from them and found them deceased.

Mercer Street runs between Glenwoood Avenue and Plum Street on the city’s South Side.
