Sylvia Chase who was one of the first correspondents of ABC’s News mag 20/20 has died.

Chase joined ABC news in 1977 and joined 20/20 show in 1978.

In December of 1985, Chase resigned ABC News to become a local news Anchor at KRON in San Francisco.

Chase had worked on a 20/20 story the late Marilyn Monroe for months. The segment, which concerned Monroe's reported affairs with President John F. Kennedy and Atty. Gen. Robert F. Kennedy never aired.

Shortly before the segment was to air on "20/20," then ABC News President Roone Arledge decided to cancel it, saying it needed more work.

Chase, who had worked on the story for three months, never publicly criticized Arledge. "It's no secret that I was disappointed, and I think it was a wrong decision," she said, but never gave that as the reason she was leaving ABC.

She said at the time that she was joining KRON simply because she thinks it has "one of the best local news operations in the country."

Wow…how times have changed.

ABC Executive Producer Shelley Ross broke the news of Chase’s death on her social media:
