Samantha Primus, a 46-year-old who is deaf and has disabilities, had been missing for three weeks.
Samantha was found on the 1 train in South Ferry.
As of Saturday night, she is at Brooklyn Methodist Hospital and she is expected to be OK. But her family's fight for justice is far from over.
"Jumping from train to train, looking and hoping she was going to get home and we found her," said her sister, Sophia Primus.
The Primus family's quest to find Samantha ended Saturday afternoon when they got a tip that she was on the 1 train at the South Ferry station.
They immediately took the ride over to the station.
A family friend said Samantha looked disoriented, tired and dehydrated.
"Both feet were swollen, her eyes were dark, her skin was dry," Sophia Primus said.
Samantha first went missing on Dec. 23 and was found later that day by a paramedic.
Her family said she was then taken to Queens General Hospital but was released that same day only to go missing again.
"My sister was lost, found and lost again," Sophia Primus said.
The Primus family said their next step is to take legal action.
"If the Nassau County police report was accurate, then clearly this hospital was not only negligent but also heartless, and appropriate legal action will be instituted," said attorney Sanford Rubenstein.
For now, however, the Primus family said they are just happy that she is safe.
"Jubilation and a weight off our shoulders, our hearts and our heads," Sophia Primus said.
The Primus family originally had planned a search party for Sunday, which they said now is cancelled.
They added that Samantha will remain at the hospital until she is healthy enough to go home.
