So I started thinking: there must be incredible stories buried in that world. Billy’s story turned out to be one of them.”\n\nAnd gay porn ended up being instrumental in the case. While researching the murder, Mason went through a trove of archival porn footage, and some of it even became evidence in the case.\n\n“There’s a videotape of a memorial award show from the gay adult industry in the early ’90s,” she said. “It’s basically a time capsule of that era. And in that footage you see someone who later became the suspected killer actually walk on stage. It’s chilling.”\n\nWhile making the documentary, Mason began corresponding with the suspected killer — a transgender woman named DarraLynn Madden, who allegedly killed London prior to transitioning — whom she was able to help the police identify.\n\n“My partner is trans, so hearing that information was like a knife to the heart. The last thing you want is a case like this being used to reinforce harmful stereotypes about trans people,” Mason said of discovering the truth.\n\nBut eventually, Mason was able to interview Madden in prison and elicited a confession.\n\n“We were taken into a maximum-security unit. She came out in double shackles with a guard standing extremely close behind her. But what struck me most was how charismatic she was,” Mason said. “The detective who interviewed her said the same thing — she’s very charming, very funny. Someone you could easily imagine having a conversation with over a beer. That makes it even more disturbing.”\n\nIdentifying the suspected killer — who had connections to white supremacy and gay bashings — was important, but Mason's main goal was to tell London’s story and provide closure to his family.\n\n“That was incredibly important to me,” she said. “Billy’s partner Marc Rabins had lived with suspicion for years. And Billy’s family never had real closure. After seeing the film, they told me they finally felt they had answers. That meant more to me than anything.”\n\n _My Brother’s Killer_ is currently premiering at SXSW.",
