Raya and Sakina, also known as ريا وسكينة, were infamous Egyptian sisters who became the country's most notorious serial killers. During the late 19th and early 20th centuries, Egypt was suffering economically due to World War I, leading to hardships for many. Raya, Sakina, their husbands, and two other men resorted to killing 17 women in the Labban neighborhood of Alexandria in 1919. The victims were primarily prostitutes who worked for the sisters in their brothel. The modus operandi involved luring the women to their homes, intoxicating them, and then suffocating them before burying their bodies underneath the houses. The sisters sold the stolen jewelry to a local jeweler, dividing the money among the six criminals. Following investigations, Raya, Sakina, and their husbands were tried, convicted, and sentenced to death, marking the first execution of women by the modern state of Egypt. This chilling case has inspired numerous artistic works, including films, television series, and theatrical productions, which have kept the story of Raya and Sakina alive in the media.
