THE BRONX - The family of a Bronx man who went missing over the weekend spoke to News 12’s Alisha Laventure about the urgency to find him.

Carlos Melendez, 79, suffers from dementia and Alzheimer’s disease. He was admitted to Bronx Lebanon Hospital over the weekend after an emotional outburst.

When his wife, Isabel Calderon, went to check on him Monday morning, she says she was told by hospital staff that he left.

She says the staff told her that her husband was being uncooperative and physical, so they let him go.

Melendez’s family says his outburst stemmed from his inability to grasp that he is not well.

"He was very sociable, and I think that's the problem,” said his niece. “He doesn't know how to deal now that he doesn't have that anymore."

News 12 reached out to Bronx Lebanon about Melendez's disappearance. The hospital has not yet responded.

Anyone with information regarding Melendez’s whereabouts can call Crime Stoppers at 1-800-577-TIPS.
