Prosecutors say house fire that killed New Jersey hospital CEO and wife was intentionally set

A fire that killed the president of a major southern New Jersey hospital and his wife has been ruled arson.

The Somerset County prosecutor's office announced its finding Wednesday.

Investigators determined the fire was intentionally set early Sunday in the master bedroom of the Montgomery Township home of 72-year-old John Sheridan and 69-year-old Joyce Sheridan. But they have not released the cause of death for either person.

John Sheridan was pronounced dead at the scene. His wife was taken to a hospital, where she died a short time later.

John Sheridan was president and CEO of Camden-based Cooper University Health Care, which has more than 700 physicians and serves more than half a million patients a year.
