why dont you ask him?
Jeff are you Johnny Gosch? see #20 and 23
If Gannon is Gosch he'd jeopardize his life by admitting it at this time unless he is in a very, very safe place. Even Johnny's mother, Noreen, will neither deny or confirm that Gannon is Gosch.
Whoever Gannon turns out to be I hope he gets his book written ASAP and distributes it worldwide so that the corrupt debauched fiends will be exposed.
