Very Idham Henyansyah, born on February 1, 1978, in Jombang, East Java, Indonesia, is a convicted serial killer known for his gruesome crimes and subsequent media presence. Prior to his criminal activities, Henyansyah was a Qur'an recital teacher and later pursued a career in modeling. He is openly homosexual and has stated that most of his victims were homosexual men.

Between 2006 and 2008, Henyansyah committed a series of murders, claiming the lives of 11 individuals. His modus operandi varied but often involved luring victims to secluded locations, where he would assault and kill them using blunt instruments or knives. One particularly notorious case involved Heri Santoso, whose dismembered body was discovered in seven parts near Ragunan Zoo in South Jakarta in July 2008. Other victims were found buried in the backyard of Henyansyah's family home in Jombang Regency, East Java.

The case gained significant media attention due to the brutal nature of the murders and Henyansyah's behavior following his arrest. Dubbed "The Singing Serial Killer," he entertained court officers, fellow inmates, and media audiences by singing songs from an album he planned to release. In February 2009, he published an autobiography titled "The Untold Story of Ryan," detailing his life and crimes.

Despite his open homosexuality, in October 2010, Henyansyah announced plans to marry a female convicted drug dealer, Eny Wijaya, whom he met in 2008 while both were detained at the Jakarta Police Narcotics Detention Center.
