I'm doing a research paper and I need some help!?

I have two ideas on what i want my paper to be about, either child abductions (kidnapping) or Madeline McCann. If you've never heard about that she was kidnapped. But anyway I need help because if I do Madeline Mccann I need to have a 3-5 page paper, and I have to use 2 books, an encyclopedia, and internet. Im not sure i will be able to find enough stuff. My other option child abduction, or like amber alert I'm interested in to but i don't know what i would say besides statistics. I need some help please!
