A Queens woman was 22 years old and pregnant when she disappeared nearly 50 years ago — but her family is still desperate for answers.

Milagros Perez Peralta was leaving an unemployment office in Williamsburg, Brooklyn, on Aug. 30, 1976 when witnesses claimed she was forced into a car, according to Manhattan Supreme Court papers filed by her brother, Rafael Perez.

Her family immediately contacted the cops in the nearby 90th Precinct, and in the 114th where she lived, Perez said.

Despite an investigation at the time, Peralta’s case went cold, said her brother, who filed a Freedom of Information Law request with the NYPD in April 2022 for any documents on his sister’s case.

“Since 1976, Ms. Perez’s family have carried on the search for their missing loved one,” the legal filing says.

But after nine months, the NYPD allegedly closed Perez’ FOIL request, claiming without explanation it had no documents about the case, he contends.

Perez now wants a judge to force the NYPD the provide the records or explain why no records exist.

The NYPD declined to comment on the litigation.
