Source-derived summary

Richard Angelo (born August 29, 1962) is an American serial killer and former nurse who operated within Long Island and West Islip, New York. In 1989, he was convicted of murdering several of his patients and sentenced to 50-years-to-life in prison.

Early life

Angelo was born on August 29, 1962, to parents who were both working in education. His mother was an economics teacher, and his father was a high school guidance counselor for the Lindenhurst school district on Long Island. He graduated from St. John the Baptist Diocesan High School in 1980 and then entered a two-year nursing program at Farmingdale State College, where he was a well-regarded honor student.

Arrest

Angelo first came to the attention of the public in October 1987 when he was suspected of poisoning a patient at then Good Samaritan Medical Center. He was accused of injecting Gerolamo Kuchich with pancuronium, a muscle relaxant, via his I.V. The patient felt unwell after the injection, and later paged a nurse to help him. Angelo was arrested for assault on the 73-year-old patient because he was the only person to match the description given to the police.

Following his arrest, Angelo confessed to having poisoned other patients with pancuronium and Suxamethonium chloride, both of which are paralytic agents used in anesthesia.

Critical limits

The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
