He and several friends of his, using expensive toys apparently bought by Tucker's wealthy parents, Tucker would wait for the other kids to become involved in a case before pretending to pull jurisdiction on them to muscle in on their playtime, insisting the FBI had jurisdiction in every single case, especially the case where Bill and Fosse kidnapped Sarah Peterson's doll.
