What happened to this Bellevue nurse?

A Bronx woman last seen in December is now the subject of a missing person investigation as police search for clues to find her.

Police said Mahfuza Rahman, 30, was last seen on Tuesday, Dec. 8, as she left Bellevue Hospital, where she worked as a nurse.

On Monday, authorities were searching her Bronx home after co-workers reported Rahman missing on Friday, the New York Post reported. Her husband, Mohammad Chowdhury, had told her colleagues in December that she traveled to Bangladesh and would return in March.

Their Bronx neighbors said Chowdhury told them the same thing and that he, too, would be going to Bangladesh with their daughter, the New York Daily News reported. No one has returned to their home since December.

“Right now, it’s a missing person investigation,” an official said to the Daily News. “We don’t have any evidence of foul play. She could have just left.”

Detectives focused on a second-story back room in their Bronx home and dug up recently laid concrete in front of the home, sources said to the Post.

Investigators reportedly found it unusual that she did not call Bellevue before leaving, and a source said to the Daily News that police are trying to secure warrants to examine the family’s financial records.
