The sister of a missing Brooklyn woman who has schizophrenia is pleading for her sister's safe return.

Nola Roberts says her 58-year-old sister, Rebecca Wilson, has been missing for two weeks.

Roberts says while she was at work on Oct. 29, she checked the cameras in her home and noticed that her sister, who lives with her, was not there.

She says when she went to her East Flatbush home, she noticed the front door was open and her sister was nowhere to be found.

She filed a police report, started putting up posters and has been calling area hospitals in hopes of finding her sister.

She's also worried because her sister, who also goes by the name Charmaine, is diabetic and needs to take her insulin regularly.

Roberts says her sister Rebecca is 5 feet, 4 inches tall, weighs about 140 pounds and has dark brown eyes.

She was last seen wearing black-and-white-striped sleepwear, with no shoes or jacket.

Anyone with any information regarding her whereabouts is asked to call police.
