I've wondered about that too! Mainly about how B.L.'s parents can get money to him without getting it traced.
Here's an idea..it probably has holes in it, but what are the holes? That day that mom went to Orlando..she was browsing around the library. She made sure that a family friend was there ? Left an envelope between 2 books.. Family friend picked up envelope, and mailed it. Some predetermined fake name, sent to General Delivery in Murphy, North Carolina. B.L. picked up the envelope, or had someone else pick it up? Maybe $1500 in cash in there.
How could L.E. track this? Just guessing.
