Medical examiner overturns suicide ruling of former hospital CEO John Sheridan
New Jersey's medical examiner has overturned an earlier ruling that the former president and CEO of Cooper Health System killed himself.
The medical examiner Friday changed John Sheridan's manner of death from suicide to undetermined on his death certificate.
The decision came after the four sons of John and Joyce Sheridan accused a prosecutor of jumping to conclusions that Sheridan killed his wife and then himself after setting their Montgomery Township house on fire in 2014.
The Sheridan sons say that they do not believe that their father killed their mother and think that both parents were killed by an unknown person.
Mark Sheridan says the family feels that a "huge wrong has been made right," but that they still don't know who killed their parents. They want the investigation reopened.
A nationally known forensic scientist hired by the sons concluded that John Sheridan was likely killed.
