Judith Permar, 56, died from a combination of trauma and possible hypothermia, according to Northumberland County Coroner James Kelley.
Permar used a step stool to reach the bin when her arm became stuck and the stool collapsed – her feet dangling just above the ground, WNEP reported. She broke her left arm and wrist, which prevented her from escaping, authorities said.
Investigators believe the woman went to the bin around 2 a.m. Sunday.
She was found around 8:30 a.m. and pronounced dead at the scene, the KTRK report said.
The coroner ruled the cause of her death accidental.
Permar’s son said she always wanted to help the less fortunate and constantly donated to those clothing bins.
In lieu of flowers, her family asks people make donations to their local SPCA or animal shelter as Judith was an animal lover.
