That letter was added a few months back to Supernaught and it’s a little bomb. Ted Bundy wrote this letter to his friend Mary on June 02, 1987, which is months after Carole supposedly took Rosa and never came back to visit.
According to the letter she did came back though :
“Thank you for picking Rosa and Carole up at the airport last month. We had a great time while they were in Florida. Carole is considering moving back to Florida. It’s all up in the air. She can’t afford to now anyway. I know Margot isn’t happy with the idea and I can see why, especially now that Jamey is returning to Gainesville. I would love to see them all more often, but I know that if I had a choice I wouldn’t want to live in Florida. All I want is what’s best for Rosa and Carole.”
