Yes, it is a scam.

Are you sure?  I dont know...

Go to 800notes.com and research 301-358-5596 or 5599 and you'll see similar comments.  This Alan Parker or Jennifer Peoples has called multiple people with the same story.  Besides, how is someone (who is not a law enforcement officer) outside your state going to do anything?  Wouldn't it have to be a federal case? I don't know.  But your local sheriff is not going to come to your house looking for you.   These people won't tell you anything about the accuser.  It's just a sorry attempt at fraud.  Google Alan Parker and you'll find many complaints.

This is a scam, there is an open investigation on this number. Law enforcement is very close to shutting this down.

Nationwide Investigations is  a valid Private Investigations firm that often locates individuals and file an application for a warrant and then send over to a process server which then in turn will file the warrant with the local county in which it is applied to.  They are not a scam.
