That is very, very far from declaring Mr. Bernhardt to be mentally ill.  If you can read the statement in its full context, then you'll understand it was an attempt to fully reconcile his wife's actions.  As I see it, given all we presently know, either she did not consider her husband a danger to himself or others when she left Hawaii or she did consider him to be a danger to himself and others when she left.  If the former, then why bother to make a phone call to the police that could worsen a future interaction between him and responding police officers?  If it was the latter, then what compelling reason made her leave him alone at such a vulnerable time?

In case you don't understand the above, then I'll repeat part of it more explicitly:  no, I have no certain knowledge Mr. Bernhardt suffered from a mental illness.

However, yes, I have difficulty reconciling Mrs. Bernhardt's actions as reported so far by the Star-Advertiser.
