I don't think it's that easy to find someone in witness protection, unless there are some other sloppy programs in the US, you, sir, are incorrect.

"More than 18,400 men, women and children have participated in it, and not one of the 8,500 witnesses or the 9,900 family members has been harmed" [1]

Now his family idk, good luck to them.
