JMO, only if Jake or Angela lie on the witness stand. That seems highly unlikely. As AC said before, the state already has enough evidence to convict GW3 and GW4. The testimony from Jake and Angela is only to confirm what the evidence shows. With all the evidence at hand, it will be impossible for GW4 to try to insert some alternate scenario into the mix.
Angela and Jake want to keep the deals they negotiated, they'll do as they're told. If not, the whole family faces the DP. JMO, Jake's intention was to make sure his family didn't face the DP.
I've always thought the podcast leaned in favor of the Wagner family, JMO. I found it interesting that they stopped doing podcasts once Jake and Angela confessed and details confirmed the Wagner family was guilty. Now they only want to discuss technicalities of the upcoming trial. I'll go out on a limb and say they're probably repeating much of what GW4's attorneys are saying.
Maybe they'll even keep podcasting after GW4 and Billy are convicted, informing their listeners about the ongoing process of endless appeals.
It's possible. Only recently I found out that a loyal group of Happy Valley locals continues to insist Penn State coach Jerry Sandusky is innocent and are trying to get him a new trial. Truth is always stranger than fiction.
