A Philadelphia woman died in a possible drowning on the Lehigh River over the weekend.

Carbon County Coroner Robert Miller said that Rosa Spadaro, 67, of Philadelphia was rafting on the Lehigh River Sunday near the area where Route 895 crosses the Lehigh when she went into the water.

She was pulled out by crews at the boat launch in Bowmanstown.

He said officials weren’t sure if she had a heart attack or drowned but an autopsy performed on Tuesday ruled out a heart attack.

Results from the autopsy are still pending, Miller said.

The Pennsylvania Fish and Boat Commission are investigating.
