The Los Angeles Times reports that the wife of John Ritter has filed a wrongful death lawsuit against two physicians, alleging that their negligence caused the actor's death in 2003. The defendants are a cardiologist who treated Ritter the night of his death, and a radiologist who interpreted the results of a preventative body scan he had received two years prior. The lawsuit alleges that had a chest x-ray been performed on the night of his death, an enlarged aorta would have been spotted, and that life-saving surgery could have been performed. The chest x-ray had been ordered, but not performed. Over $67 million in damages are being sought from the doctors, according to the Los Angeles Times.
