Denis Gorbunov

The trial began in early 2006. On March 22, 2006, the Chelyabinsk Regional Court found him guilty on all charges and sentenced Gorbunov to life imprisonment. Only two days later, Gorbunov was found dead in his cell at SIZO-1, having hanged himself with a sheet tied to the cell's window bars. He left behind a suicide note, in which he stated that the murders were committed out of personal greed and that he asked forgiveness from the victims' relatives.

Soon after his death, the local prosecutor's office opened a criminal case and ordered an inspection regarding the conditions of the prison. The Directorate of the Federal Penitentiary Service noted that there was a shortage of guards and up to 20 inmates per guard in the protective unit. It was also noted that in 2005, a total of eight inmates had committed suicide around various penitentiaries in Chelyabinsk Oblast, half of whom had been registered with psychiatrists. The problem of staff shortage was raised by the Directorate at a board meeting on March 24, 2006. Subsequently, all penitentiaries in the region had video cameras installed in their cells so they could observe the inmates at all times.

During the course of the investigation, authorities quickly established that the perpetrator introduced himself as a potential buyer to the victims, most of whom posted advertisements for the sale of wedding dresses. In addition to a dedicate task force, the investigation was aided by local police and other divisions of the Department of Internal Affairs. Eventually, law enforcement officials decided to post fake advertisements in order to lure the killer, and on May 17, 2005, Gorbunov was arrested when he met and attempted to attack an undercover police officer.

In early 2004, Gorbunov was granted parole and released, whereupon he returned to Chelyabinsk. As he was a convicted felon, he struggled with finding a decent job and resorted to doing low-skilled labor and odd jobs. By mid-2004, he resumed his drug habits, and due to the financial difficulties that brought on, he decided to start robbing people. Not long after, he started murdering his victims.

Denis Alekseevich Gorbunov (Russian: Денис Алексеевич Горбунов; July 28, 1977 – March 26, 2006), known as The Ad Killer (Russian: Убийца по объявлению), was a Russian serial killer who murdered five women during robberies in Chelyabinsk from December 2004 to May 2005. Convicted and sentenced to life imprisonment for his crimes, he committed suicide two days after his conviction.

Little is known about Gorbunov's early life, other than the fact that he was born in Chelyabinsk on July 28, 1977. In the early 1990s, due to the social and economic turmoil brought on by the collapse of the USSR, the Gorbunov family experienced financial struggles. By the mid-1990s, Gorbunov lost all interest in pursuing an education and turned to a life of time, developing a drug addiction in the process. During the remainder of the 1990s, he would be repeatedly arrested on charges of theft, assault, robbery and drug possession. For one of these convictions, he was found guilty and trial and sentenced to 8 years imprisonment.
