Actor Henry Winkler has testified in the trial of a lawsuit against two doctors over the death of actor John Ritter in 2003.
Winkler told Los Angeles County Superior Court jurors Wednesday that he last saw Ritter on the set of the show "8 Simple Rules … For Dating My Teenage Daughter."
Winkler said that later that night he received a telephone call saying Ritter had died.
The sitcom star died of a torn aorta after going to a hospital where he was treated for a heart attack.
Ritter's family is suing a radiologist who had earlier given Ritter a body scan and the cardiologist who treated him at the hospital.
