Odds are that whatever get's found..if anything at all...the Mcmurderers will discount..just like everything else that has ever pointed at them being the culprits. Read the police interview transcripts..then look at all the evidence...blood in the apartment..cadaver dogs giving positive reading for a dead body in the apartment..the list goes on. But when you have friends in high places then anything can be rebuked.
If that had happened here they'd have been doing time a long time ago.
