To R. Mutt:
He was "declared the killer" by the police because he IS the killer. You say he was "dumb enough to be interviewed by the detectives". People who are innocent and have nothing to hide don't mind talking to the police. Why not? If you did not commit the crime, if there is no evidence pointing in your direction then you have nothing to fear because they police will not find anything than can tie you to the crime.
Naposki is an sociopath who murdered a man in cold blood to get his money. His girlfriend gave him the key to the gate so he could get in the door. They are BOTH cold blooded killers who almost got away with it.
Good job Larry Montgomery (and everybody else who has worked this case) in the OC D.A's office. EXCELLENT police work in bring these two killers to justice.
