Adam Joel Anhang Uster (March 8, 1973 – September 23, 2005) was an entrepreneur and real estate developer; he was murdered at the intersection of Calle San Justo and Calle Luna in Old San Juan, Puerto Rico in September 2005. He was leaving the Pink Skirt Nightclub/Dragonfly Club with his estranged wife, Áurea Vázquez-Rijos, from whom he was finalizing a divorce, and was knifed and beaten to death on the street, while she suffered minor injuries during the attack. The event was highlighted as the Pink Skirt Murder in a television exposé on Dateline NBC. Vázquez-Rijos, known in the media as the "Black Widow", fled jurisdiction to Italy in 2006 but was discovered and extradited to Puerto Rico in 2015, and was convicted of being a co-conspirator in her husband's murder in October 2018.
