the guy seem to be kind of a schmuck but i have yet to see anything that points to him being guily of murder. the guy is probably selling stuff because he needs the money, as best i can tell he hasn't been able to work regularly and i can assure everyone that no insurance company has paid any death claims on the life of his wife at this point. the authorities always jump on the husband when they have no other suspects. if they didn't do that they wouldn't be doing anything as they obviously don't have the foggiest clue about what happened to that lady.
i find it puzzling that his wife's family wholeheartedly supported him until they found out that he lied about the affair. excuse me, but men always lie about affairs, and i can't imagine someone volunteering that info when his wife has disappeared. last time i checked, california is a no-fault divorce, community property state. if he wanted to ditch the wife for some younger tuna, murder would not be the easiest option.
as to polygraphs, i almost never allow my clients to submit to a test by a police examiner without having a private test run first. of course, the police generally refuse to test your client if they find out that he's been perviously tested as they want him green and dumb when he sits for their test. most of the time the police test is done by an officer who, after the formal test is complete, will keep your client incommunicado post test while he interrogates him and tries to get a confession without the lawyer present (a right the client waived in order to take the test). if that fails, they just come out and call the test "inconclusive" and you're right back where you started.
why do you think the police went to the media right off the bat and insinuated that this guy was a suspect. remember all the publicity the cops generated with that sonar image they found at the marina where he keeps his boat, implying that it may be his wife's body? they already knew that was nothing, that was done for no other reason than to watch him sweat and see how he reacted. they didn't care about the fact that they had no evidence that pointed to him or how it would affect him. they just wanted to get a break in the case so they wouldn't look like incompetents. i promise you if the police had any evidence at all that suggested that this guy was connected to his wife's disappearence he already would have been charged and arrested. the fact that he hasn't speaks for itself.
and scott-atlanta, a criminal justice system whereby one is arrested without probable cause and held until he proves himself innocent is the format that was used by communist states, the star chamber, and before them, the inquisition. our systen presumes innocence and requires the state to prove guilt beyond a reasonable doubt. i prefer things that way.
