FORT WAYNE, Ind. (AP) — The coroner’s office in Allen County says the death of a 72-year-old woman who rushed into a Fort Wayne pond to save her grandson was an accidental drowning.

According to WANE-TV, Sharon Shively died early Saturday at a local hospital about 18 hours after she was pulled from the pond.

The coroner’s office said Tuesday that her death was an accident.

Authorities said Shively ran into the pond after noticing her 6-year-old grandson had drifted 15 to 20 feet from shore.

A neighbor pulled the boy from the water before trying to rescue Shively. She was unresponsive when she was pulled from the water.

Authorities say the boy was in good condition.
