All He Really Knew
Aaron couldn't help but commend himself on his acting skills. Gray seemed utterly unsuspicious about where the evidence against him came from. He wouldn't have acted the way he did on the phone otherwise.
He and Keeley had discussed this possibility. As a worst case scenario, even if a good lawyer managed to reduce his sentence, there was no way Gray would be able to get off completely. Not being found near the scene of the crime without a valid alibi anymore.
He sincerely hoped the police would be able to prove it had been premeditated. Then Gray would be out of their hair for a minimum of twenty years. After that…well, they would cross that bridge when they got to it.
He had already contacted Neal Ashley and told him the simple version of the situation. It wouldn't do for the lawyer to know more than Aaron supposedly did when he showed up at the precinct. He passed on exactly what Gray had said over the phone and nothing more.
