Mirin Nieves-Rivera was 36 when she was last in contact in Buffalo, New York, with an official last-contact date of October 15, 2018. Her family says they had not seen or heard from her for about two months before that date. Mirin is described as a woman of Asian descent, black hair, brown eyes, 5 feet 3 inches tall and about 110 pounds.

The Buffalo Police Department is handling the investigation. The case was added to the NamUs database on June 25, 2020, but police and family report few significant leads and no public breakthroughs. The circumstances of her disappearance remain unclear and the case is still listed as an open missing-person investigation.

If anyone in Buffalo around summer–autumn 2018 had contact with Mirin, knew where she worked or spent time, or has any information about her movements, please share what is known with the Buffalo Police Department.
