They say an investigation of the April 7 posting led to 24-year-old Joshua Stagnitto of Brockport, 15 miles west of Rochester. He was arrested Thursday and charged with a misdemeanor count of falsely reporting an incident.
An investigator says Friday that Stagnitto claimed the listing was a joke. The children, boys ages 1 and 2, remain in their parents' custody.
Police don't know if Stagnitto has a lawyer. There is no phone number listed for him in Brockport.
