Luis Ortiz was nine years old when he vanished in Manhattan on March 6, 1973 after being sent to a nearby corner store for groceries. His body was later found in a basement stairwell at 200 West 106th Street. Investigators described a frenzied, brutal attack: dozens of stab wounds and severe mutilation that led authorities and the public to view the killing as part of a pattern rather than an isolated random assault.

The crime was linked by police and press to a string of similar attacks in 1972–1973 attributed to an unidentified predator nicknamed Charlie Chop-off, a series that targeted children and involved extreme stabbing and sexual mutilation. Police said they were working with witness information and a suspect description and increased patrols around schools amid intense public pressure and community fear.

Attention later focused on Ernesto Erno Soto, a man with extensive psychiatric hospitalization, who was arrested on May 15, 1974 after accosting a child and reportedly confessed to another killing in the series. Questions about Soto’s whereabouts, his mental state, and his fitness for trial prevented the case from resolving into a conviction for Luis Ortiz’s death; Soto was later found unfit for trial and confined in the forensic psychiatric system, and no public conviction tied the murders definitively to a single perpetrator.

Did anyone on the Upper West Side or Harlem border in 1973 see Luis Ortiz that afternoon or remember a suspicious person near 200 West 106th Street?
