New Jersey's medical examiner has overturned an earlier ruling that the former president of a hospital 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 he killed his wife and then himself after setting their house on fire.

Mark Sheridan says the family feels that a "huge wrong has been made right," but they still don't know who killed their parents.

They want the investigation reopened.

A nationally known forensic scientist concluded that John Sheridan was likely killed.

Sheridan is the former president and CEO of Cooper Health System.
