there is no proof Patsey wrote that letter and I think at this point anymore bashing of the Ramsey's is rediculous.
Many believe she did write the letter because the ransom requested was the exact amount of John's Christmas bonus ($18,000, I believe).
Some people can not and will never admit that they were wrong. They've spent 10 years saying she was guilty - now when someone is arrested for the murder and it's not a Ramsey, they still can't admit it.
