Woman deemed fit for court over alleged stabbing of tourist at Macy’s

Kerri Aherne, 44, has been deemed fit to face court after a psychiatric evaluation, in a case involving the alleged stabbing of a California tourist in a Macy’s bathroom. Prosecutors say the woman was changing her ten-month-old baby’s nappy when she was attacked, making the case notable for the child’s presence and questions about Aherne’s mental health and release from hospital.

The alleged attack took place at the Herald Square store on 11 December 2025. The mother suffered wounds to her back, shoulder and arm and was taken to hospital in stable condition; the baby was not injured. Prosecutors say Aherne had bought a knife in the store and attacked the woman, who was helped to subdue her by the baby’s father. Aherne faces charges including attempted murder, assault and endangering a child; her remand was continued, with her legal team expected to return with a motion by 21 December.
