HBO's latest docuseries examines a rash of murders in the early '90s known as the "last call killings," as each victim was picked up in the middle of the night at a gay bar in New York City. The first episode of "Last Call," which premiered Sunday, centers on Peter Stickney Anderson, a banker who lived in Philadelphia at the time of his death, and Thomas Mulcahy, a salesman from Massachusetts whose body was found in Burlington County, New Jersey. While no one was ever tried for Anderson's death, Richard Rogers was convicted of Mulcahy's murder in 2005 — and many believe he is responsible for all four killings. He is currently serving two consecutive life sentences for the murders of Mulcahy and Marrero, who will be spotlighted in future episodes. Last Call is based on the 2021 nonfiction book of the same name by Elon Green. It covers three years, during which four gay men disappeared from Manhattan, only for their dismembered bodies to be discovered off highways in Pennsylvania, New Jersey, and New York. The series interviews investigators who worked on the cases, victims' children and partners, and queer activists who demanded a more robust response to rising hate crimes against the LGBTQ+ community in the 1990s. #Queer Up Entertainment
