The Season 3 finale of Only Murders in the Building has concluded, revealing the identity of the killer and setting the stage for the next chapter. The show, available on Disney+, revolves around the adventures of Charles, Oliver, and Mabel, portrayed by Steve Martin, Martin Short, and Selena Gomez, respectively. The trio resides in the esteemed Arconia building and embarks on a journey to unravel the mysteries behind their neighbors' untimely demises, documenting their investigation through a podcast.

In Season 3 of Only Murders in the Building, the focus shifts to unraveling the mystery of the murder of the renowned actor Ben Glenroy, portrayed by Paul Rudd. The previous seasons have been filled with unexpected twists and suspenseful moments, with both concluding in cliffhangers involving fresh homicides. Season 2, for instance, concluded with Ben Glenroy tragically collapsing dead on stage. Now, in Season 3, the primary inquiry revolves around determining who is responsible for his untimely demise. In this discussion, we will explore the details of the murder case and also delve into the conclusion of Season 3 of Only Murders in the Building. Please be advised that there will be substantial spoilers for Season 3 ahead.

Who killed Ben Glenroy in Only Murders in the Building Season 3?

It turns out the killing pair were a mother-and-son duo: Donna and Clifford Demeo. Donna attempts to poison Ben and Clifford pushes him down the elevator shaft.

Let's delve into the intricate details surrounding Ben's demise. Although Ben faints on stage at the start of Season 3 and technically succumbs to death for approximately an hour, he miraculously reappears unharmed. In fact, he even attends the cast party, delivering a foreboding speech about how his near-death experience has compelled him to become a better person towards those in his life.

We now have the understanding that Donna Demeo, the show's producer, was the person responsible for poisoning him. She achieved this by covertly placing rat poison on a cookie and leaving it in Ben's dressing room, which he unknowingly consumed while emotionally vulnerable. What motivated her to commit such an act? Well, she wasn't the only producer, as this marked her son Clifford's initial foray into the industry. After stumbling across a scathing review of the play which singled out Ben as the main issue, Donna took drastic measures to salvage her son's career, thus resulting in Ben's murder. Additionally, her terminal illness has made her more reckless, to the extent that she is even willing to take the blame for Ben's untimely downfall.

See, although Ben is revived, he is denied the opportunity for redemption when his lifeless body unexpectedly plummets through the Arconia's elevator ceiling while our main trio is riding it. This unfortunate incident occurs because Clifford, in a desperate attempt to salvage the show and protect his mother, forcefully pushes Ben. In fact, Clifford confesses that he had never intended for Ben to be a part of the show in the first place. Consequently, when Ben realizes that his own mother has poisoned him, Clifford reacts with aggression.

How does Only Murders in the Building Season 3 end?

By the finale of Only Murders in the Building, Donna and Clifford Demo find themselves in custody, admitting their actions while maintaining that their motivations solely revolved around safeguarding one another.

Regarding other events in the season finale, despite facing numerous challenges, Oliver's show Death Rattle is greeted with positive acclaim, and he even enjoys the spotlight on opening night. Additionally, his relationship with Loretta remains intact, resulting in a happy ending.

Moving on to our other main characters, Charles receives texts from Joy, suggesting potential complications. Furthermore, Mabel might be considering a move to LA with her new romantic interest, Tobert, which raises questions about the future of the podcast.

However, it seems there is one additional case that needs to be addressed. You see, Sazz Pataki, Charles' stunt double portrayed by Jane Lynch, is casually exploring Charles' apartment when she is unexpectedly shot by an unidentified attacker. As she hovers on the brink of death, she painstakingly scribbles a message on the floor using her own blood, abruptly concluding the episode.

It appears that a fresh murder has occurred within the building, leaving Season 4 to untangle the mystery.
