Scammers push people to pay with iTunes gift cards

I'm dealing with the guy says his name is Nick Patrick Scott Malone age 52 single dad with a daughter age 12. He says he's an only child and both his parents are deceased. He says he's an engineer and he had to go to Germany for work for two weeks and it up going into 3 weeks claiming that he is sending a box of money that was found in a tunnel where they were working, and that he needed my email address to get the notice from the private FedEx. I received an email which I did not open, that said that there is something there for me a package and that I need to verify my full name and address in order to have it delivered. I contacted FedEx they said they investigated and there was no package for me. When I confronted supposedly Nick he said that is because it is a private FedEx and they do things differently. I researched him and checked all data bases including purchasing Intelius which gives you information on people phone numbers Etc. He is nowhere in any database. He had me buy two separate times, iTune cards at $100 each. Something about, to help set up his phone. I was not aware how to use iTune cards and that it doesn't do that. after doing all my research I've asked him several times for his driver's license because when I asked him for his address the first time he gave me a bogus one that went to a Chase Bank near my home, and the second one to some place that was a trailer manufacturer home that was full of junk and crap everywhere. I went up to the place and talk to the kid who lived there and asked if Nick was there or his daughter he said nobody's there by this name and then told me what his last name is which I checked in the Intelius database which the kid was telling me the truth. I immediately went to the sheriff department and filed this information. I'm continuing talking to this person because I want to catch him! I said I need to speak to his daughter who lives here in the states. I sent him a picture of the Junkie property that I was at that he claimed was his address that he gave me, which supposedly he lives in a big house which he still has a mortgage with his daughter. Last night I asked for his daughter's phone number so I could talk to her, I never got it this morning he said he fell asleep, and he gave me a phone number and said this is his daughter's number to call her now. I put that number into the database Intelius, come to find out that number belongs to a deceased man that died in 1999. I'm hoping with the iTune cards, that the police department or whoever does investigations will be able to track who cashed or use those serial numbers. Does anybody know if that's fact can they track somebody by cashing in or using those numbers?
