This confession ought to stick, even if it did occur in a mental hospital. I'd still like to know, if that PO box was his and or how long he had the alias.
Is is common practice for people to be admitted under alias'?
My sister is a nurse. We were talking about the alias last night and she said the hospital she works at will do the same thing. If it is a patient with a high profile, then they will get an alias. Anyone calling from the press or anyone not cleared by the family or patient can't get information.
