Steven Cropper was 7 when he was found dead on August 17, 1973, in a tenement at 325 East Houston Street in Manhattan’s Lower East Side. Responding officers and later autopsy reports described staged elements at the scene—shirt pulled high, pants tugged down slightly, sneakers removed—and razor slashes on his body; the fatal wound was a laceration to the main artery near his left elbow. His parents, Catherine and William Cropper, were located and brought to Bellevue to identify him.

In the weeks after the killing police pursued hundreds of tips, circulated a composite sketch, and questioned many people, including known sex offenders. In late May 1974 Ernesto Erno Soto was arrested after accosting a nine-year-old and taken for psychiatric evaluation; some witnesses later identified him and he confessed to Steven’s killing. Hospital records and a surviving victim’s inability to identify Soto clouded that confession, and there was no physical evidence publicly tying him to the crime. Soto was found not guilty by reason of insanity and committed to a maximum-security psychiatric institution; he had also been cleared in a 1976 report of other sex-mutilation murders, though he remained a suspect in Steven’s death and the file was still technically open.

If anyone knew Steven, his family, or saw someone matching the composite in 1973–74, please share what might help the investigation.
