MICHIGAN CITY, IN — Indiana serial killer Orville Lynn Majors, the former male nurse who was found guilty in 1999 of murdering six hospital patients, has died.
The 56-year-old native of Linton was serving a 360-year sentence for the six murder convictions, according to the Indiana Department of Correction.
Indiana State Prison correctional officers were assisting with a medical pass for Majors Sunday afternoon when he became unresponsive.
Staff performed CPR and applied a defibrillator, but he was later pronounced dead at Franciscan Health Hospital in Michigan City.
An autopsy conducted Monday determined that he died of natural causes related to a heart condition, according to the release.
Majors was a licensed practical nurse when he murdered patients at the former Vermillion County Hospital by injecting them with heart-stopping potassium chloride — earning him the nickname “The Angel of Death.”
Though he was convicted of six murders, authorities believe that he may be responsible for more than 100 deaths. Investigators have made a list of more than 150 suspicious deaths at the hospital, and exhumed over a dozen bodies during a multi-year investigation.
While Majors was a nurse, an investigation by a nursing supervisor showed that an ICU patient died every 23 hours when Majors was working, compared with every 552 hours when he was not on duty.
In March 1995, he was suspended. In December 1995, a state board found that, among other abuses, Majors was giving unauthorized injections, and suspended his nursing license indefinitely.
Majors’ earliest projected release date was listed as July 1, 2177.
