The Senior Roll Call Lifeline checked in on the woman who lives in an apartment on Welsh Tract Road.
When she didn't answer the phone Wednesday morning, the lifeline called her neighbors.
That's when neighbor Danielle Waters found the elderly woman on the floor; she had fallen out of bed while sleeping.
She was taken to the hospital for evaluation.
