 One of the main suspects in the train crashes is Walter Gray (Lloyd Whitlock), the airline manager and Larry's boss, who stands to gain if the L & R Railroad loose contracts.Suspicion is also cast on Tom Jordan (Matthew Betz), a recently discharged and disgruntled railroad engineer.Another possibility is that Frank Stratton (Edmund Breese), an escaped convict who had wrongfully been convicted, may be the Wrecker.
