Sara Nicole Ahern was 33 when she was last known to be in Frederick, Maryland, on April 11, 2023. NamUs lists her as a white female with brown hair and brown eyes and shows Frederick as the place of last contact. A friend received a voicemail from her about 12:19 p.m. on April 12, 2023, and her social media activity stopped after she went missing. Her current cellphone has been reported disconnected and local checks of area hotels and the hospital did not locate her.

Sara did not have a confirmed local address at the time and was reported missing on April 15, 2023; Frederick Police Department is the investigating agency. Public notices say she was known to frequent parts of the Baltimore–Washington region, including Carroll and surrounding counties, which widens the area where she might have been seen. Photos were added to her NamUs entry and the record was created in early September 2025, reflecting ongoing attention to the case.

Anyone who remembers seeing someone who fits Sara’s description, or who has even a small detail that might place her after April 11–12, 2023, is urged to contact the Frederick Police Department with tips.
