A woman who formerly was a member of the famed vocal group The Platters has been missing for days after last being seen in Brooklyn, according to police and her daughter.

Sandra Hall went missing after 4 p.m. Friday in the vicinity of the Atlantic Terminal Mall, near Barclays Center, according to police. A statement from the family of the 80-year-old Hall said she was last seen boarding a subway at Atlantic Avenue.

Hall, who police said is about 5-foot-3, has dementia and can get confused or disoriented, according to the family. She was last seen wearing grey pants, white sneakers and a pink shirt over a white long-sleeve shirt.

“Sandra is more than just our mother; she is a warm, vibrant woman who once brought joy to audiences as part of The Platters. We just want to bring her home safely,” said her daughter, Star DaSilva.

The Platters were initially formed in 1952 and are most famously known for their hits “The Great Pretender” and “Only You.” Hall, who went by the stage name Sandra Dawn, was not part of the original lineup, but joined the group in 1965.

Anyone with information regarding Hall is asked to call the NYPD’s Crime Stoppers Hotline at 1-800-577-TIPS, or submit their tips on the CrimeStoppers website.
