JonBenét Ramsey's father wants DNA on infamous ransom letter tested

It's been nearly 30 years since his innocent little girl was murdered, but John Ramsey is never going to stop trying to figure out what happened to JonBenét Ramsey.

According to oxygen.com, John Ramsey wants the ransom letter that was left at his house to be tested for DNA.

Here's the letter that the Ramsey family found in their residence on Dec. 26, 1996:

Listen carefully! We are a group of individuals that represent a small foreign faction. We do respect your bussiness [sic] but not the country that it serves. At this time we have your daughter in our posession [sic]. She is safe and unharmed and if you want her to see 1997, you must follow our instructions to the letter.

You will withdraw $118,000.00 from your account. $100,000 will be in $100 bills and the remaining $18,000 in $20 bills. Make sure that you bring an adequate size attache to the bank. When you get home you will put the money in a brown paper bag. I will call you between 8 and 10 am tomorrow to instruct you on delivery. The delivery will be exhausting so I advise you to be rested. If we monitor you getting the money early, we might call you early to arrange an earlier delivery of the money and hence a [sic] earlier delivery pick-up of your daughter.

Any deviation of my instructions will result in the immediate execution of your daughter. You will also be denied her remains for proper burial. The two gentlemen watching over your daughter do not particularly like you so I advise you not to provoke them. Speaking to anyone about your situation, such as Police, F.B.I., etc., will result in your daughter being beheaded. If we catch you talking to a stray dog, she dies. If you alert bank authorities, she dies. If the money is in any way marked or tampered with, she dies. You will be scanned for electronic devices and if any are found, she dies. You can try to deceive us but be warned that we are familiar with law enforcement countermeasures and tactics. You stand a 99% chance of killing your daughter if you try to out smart [sic] us. Follow our instructions and you stand a 100% chance of getting her back.

You and your family are under constant scrutiny as well as the authorities. Don't try to grow a brain John. You are not the only fat cat around so don't think that killing will be difficult. Don't underestimate us John. Use that good southern common sense of yours. It is up to you now John!

Victory!

S.B.T.C.

The letter raised a lot of questions, and some people even believed that the girl's mother may have written it.

Why would the criminals have lingered at the crime scene long enough to write a three-page letter? How did they know to demand $118,000, almost the exact amount of John's Christmas bonus the previous year? Since the girl was already dead, why ever write the letter in the first place?

The letter seems to have produced more questions than answers since it was first found, but maybe we're close to using it to help solve the case once and for all.
