There have been no charges brought against the two suspects for Jarens murder.You would think if they were involved that the police would have found some evidence somewhere,at least in their car,but nothing has been said that any real evidence has been found.As far as their storys not adding up that could be because they could have been doing something else that they were ashamed of and lying about but not nessecarily the murder.
They won't charge them until they feel they have a really strong case. They wouldn't charge with the hopes of continuing their investigation. Because once charged the time starts ticking and they have a right to a speedy trial. Defense could force that issue and LE would still be out investigating during trial. Only get one chance so they will take their time and gather all the info they can... Moo
