Kidnap for Ransom?

*Update - seems Robert's parents PAID the ransom, but Robert was NOT returned.  THe FBI is making this a top priority.  The family is offering $250,000 reward.  I hope Robert didn't kidnap himself and is putting his family through this, then again the alternative is worse, so let us hope he is alive and well somewhere.

A young man is missing.  There was a ransom note to his parents.  The specifics have not been shared with the public, but it is said that the signature name was "unique and specific".  

Robert Wiles age 26 went missing from his parent's flight maintenance facility.  Originally, the parents offered a $10,000 reward for his safe return, but now after receiving the ransom note two days after his disappearance, they have increased that reward to $250,000.

I have some questions.

1. How much do the kidnappers want?  Is it more than $250,000?

2. These types of kidnappings are really rare and most likely has been orchestrated by someone they know, because the kidnappers have to know the parents A) Pay the Ransom and B) They have the money.

3. Has there been proof of life?

I bet the FBI has this under control, but don't they know the kidnappers know they are asking for $250,000 for someone to betray them?

Robert was single and working for his parents who have several businesses.  I hope Robert is ok, but I can help thinking this is a huge illusion.

I will keep you posted.
