Only Murders in the Building: Why did The trio suspects that Loretta may not be the true killer.?

In the episode "Thirty" of the TV show Only Murders in the Building, the trio consisting of Charles, Oliver, and Mabel makes progress in their investigation into the murder of Tim Kono, who is more commonly known as Ben. Throughout their investigation, they follow various leads and uncover new information that leads them to suspect Loretta, who initially confessed to the murder, may not be the true killer.One of the pivotal moments that leads the trio to suspect Loretta's innocence is when Charles reveals his alibi, clearing him of any involvement in the murder. This realization causes them to shift their focus towards finding the real murderer in order to convince Loretta to retract her confession. They understand that if they can prove someone else committed the crime, Loretta's confession loses its weight in the eyes of the law.To gather more evidence, the trio decides to investigate Ben's activities leading up to his death. They start by exploring his connections to Broadway and the 35th street area. They initially plan to enter a suspected front for a brothel, believing it might hold crucial information, but are unable to gain entry. Instead, Charles pretends to cry, successfully gaining access to a fabric shop where they meet women from Ben's sewing circle. These women reveal that they last saw him on the opening night of the play Death Rattle and helped him sew customized hankies for the cast and crew.Diving deeper into the timeline of events surrounding Ben's murder, the trio listens to voicemails left by Ben, expressing his distress and feelings of being surrounded by untrustworthy people. They focus on the 30-minute window between Ben's arrival at the theater and his distressed voicemail. By analyzing police interrogations, they discover that Ben was late for the show and had an argument with KT, the stage manager. They also uncover that Ben was fasting and was punched by Charles during rehearsal. Donna, Ben's mother, mentions that Ben looked bad and complained about Charles and Loretta. Additionally, Tobert, a behind-the-scenes filmmaker, approached Ben with his camera, and Ben took it into his dressing room to have a conversation with an unidentified individual, caught on camera.With this new evidence, the trio begins to suspect that the mysterious person Ben was talking to on camera might have poisoned him. They believe that Ben's murder was premeditated and orchestrated by someone who wanted to get rid of him to save the play. The motive could have been a negative review criticizing Ben's performance, which Howard, another character involved in the investigation, discovered among the shredded documents.Despite their suspicions pointing away from Loretta, the trio realizes they need more time to solve the case and exonerate Dickie. They understand that rushing the investigation may lead them astray or fail to uncover the true culprit. Nevertheless, they are determined to clear Loretta's name and bring the real killer to justice.In a race against the clock, the trio devises a plan to prove Dickie's innocence and secure Loretta's release from jail. They suspect Donna, who had both the motive and opportunity to commit the murder. However, they also acknowledge the difficulty of solving the case in time. With Mabel's quick thinking and her "bride" status commandeering a cab, they rush to the courthouse, posing as Mabel's fathers to gain access. At the courthouse, they locate Loretta and convince her not to plead guilty, promising to prove Dickie's innocence. Reluctantly, Loretta chooses to trust their judgment.As the tension escalates, Oliver inadvertently adds to the suspense by dramatically snorting when asked about the real killer. This emphasizes the high stakes involved as the trio prepares to present the evidence that will prove Dickie's innocence and reveal the true murderer.The decision of the trio to suspect Loretta of being innocent is based on their meticulous investigation, the uncovering of new evidence, and the realization that Charles's alibi clears him from suspicion. By examining Ben's activities before his death, the trio identifies potential motives and opportunities for other characters involved in the story. Their ultimate goal is to exonerate Loretta, as her confession loses credibility if they can prove someone else committed the crime. The path they are on leads them to suspect that the murder was premeditated and that Ben's death was orchestrated by someone who had reasons to remove him from the equation, possibly to salvage the success of the play. As the investigation intensifies, the trio becomes more determined than ever to uncover the truth and bring justice to all those involved.
