A family is demanding to know how their elderly loved one with dementia was able to wander out of a rehab center and was later found at a mall.

The family says Marie Ciranni, 90, wandered away from the Massapequa Center Rehab facility Thursday night. She later ran into good Samaritan Jeanne Morgan who was able to help out.

Morgan says she was just dropping off a night deposit at the Chase bank outside the Sunrise Mall when Ciranni came up to her car at around 11 p.m.

Ciranni had somehow gotten out of the facility and walked more than a half a mile across busy Sunrise Highway to the empty mall.

Her son, Michael Ciranni, says she was recovering at the Massapequa Center from a fall. He has no idea how she was able to leave the facility, but a police report was filed. The Massapequa Center director told Michael Ciranni he is looking into what happened.

Michael Ciranni says he is not taking his mother back to the facility and opting for in-home care.

News 12 Long Island reached out to the director of the facility but has yet to hear back.
