SNL writer’s sister vanished — now her boyfriend and rival face charges in deadly love triangle

Christina Downer, 38, disappeared in September 2025 and is presumed dead, though her remains have not been found. Los Angeles County prosecutors have charged her boyfriend, Delorean Bijon Brandon, with first-degree murder, while his former girlfriend, Kaylee Nicole Markowski, faces two felony accessory charges; investigators say the case involved an alleged effort to conceal Downer’s disappearance.

Court records describe earlier allegations of stalking, threats and domestic violence between Downer, Brandon and Markowski. Downer and Brandon each sought restraining orders against Markowski, but their requests were dismissed after they did not appear; a later request by Brandon was rejected. Police say messages sent from Downer’s phone helped create a false account that she had left voluntarily, and her phone was later found on Santa Monica Beach.
