An 80-year-old Brooklyn woman who was missing for days has been found. 

Sandra Hall, 80, is the former singer for the hit group The Platters. She disappeared Friday at around 4 p.m. near Atlantic Terminal. 

Hall's daughter Kahtia DaSilva said Wednesday that Hall had been found in New York Presbyterian Hospital and is doing well. 

Hall went missing Friday after spending time at the Atlantic Terminal Mall.

"We don't know where she's been sleeping, what she's been eating," DaSilva said before Hall was found. "I'm very concerned."

DaSilva said Hall has dementia and was in the area with her caretaker, who's DaSilva's niece, at the time of her disappearance. DaSilva said Hall separated from her caretaker at the Atlantic Avenue-Barclays Center subway station slipped through a turnstile, and got on an uptown 2 train. 

"She just hopped on, and by the time my niece, her caretaker, was able to get her bearings, the train had already gone," DaSilva said. 

DaSilva said Hall likes to be independent, but had never gone missing for several days.
