Events of Criminal Case
Carl was flagged as a suspect moments after he informed Jones and the player that Rachel was missing. Rachel was found murdered later on, and the team did not hesitate to inform Carl about it. When asked why he did not inform them about Rachel's missing incident sooner, Carl stated to the team that he could not tell them about it earlier as he was fired by Rachel because she did not like his camerawork. And later, Carl went to Rachel in hopes of getting his job back, but Rachel was not in sight. At first, Carl assumed Rachel was just avoiding him, but later realized that something was wrong. He also stated that he had started to get bad feelings ever since Rachel started hanging out with Drake Ribbs, an ex-military soldier.
As the investigation went on, the team found Rachel's USB stick inside a cryptex under Alden Greene's desk. When asked about it, Alden claimed that the USB stick was given to him by Carl. After hearing this, the team went straight to Carl, who explained that Rachel's USB stick contained all of her research and most of them concerned Alden. So he took advantage of it and sold it to Alden for extra money since Rachel did not pay him well. After finding this out, Rachel fired Carl for his betrayal—exposing Carl's lies to the team in his previous conversation with them.
Carl was found innocent after Rachel's murderer turned out to be none other than Alden Greene.
Post-trial, Carl requested the team's help to find Myriam Priest's (Rachel's grandmother) phone number (which he had unintentionally lost in a notepad) so that he could ask her to fetch Rachel's "CCN Best Reporter" trophy. The team did not hesitate to search the Grim News Headquarters and eventually found the notepad, thus giving it back to Carl, who was thankful and relieved as he wanted Rachel's prize to end up with her family. The team felt Carl did the right thing after he had wrongly sold out Rachel to Alden, feeling that Rachel could finally get the recognition and respect she deserved.
In Rachel's memory, Carl wanted the team to celebrate a meal at her favorite diner since he believed Rachel would have done the same if she was still alive.
