The sons of a prominent New Jersey couple say a prosecutor concluded that their father killed their mother and himself, then made the evidence fit the theory.

Lawyer Mark Sheridan on Monday sent an open letter to the Somerset County Prosecutor's Office laying out why he and his brothers fault the prosecutor's finding on the deaths of John and Joyce Sheridan.

The couple was found in their home in September after a fire. It was six months before a cause of death was announced for John Sheridan. The former state government official was CEO at Camden's Cooper University Hospital.

Mark Sheridan says some basic facts were wrong on an autopsy. He and his brothers have said they intend to sue.
