Josef Kott and Michael Kutílek

In 2008, Kutílek confessed to a fifth murder he committed in the spring 1990, without Kott. The victim was a 19-year-old young man whom Kutílek had stabbed in the heart. This murder, however, did not change Kutílek's sentence.

In 2006, Kutílek claimed he was the sole perpetrator and that Kott had nothing to do with the murders. The court dismissed his proposal, with no new evidence to re-establish the case.

Kott never admitted his guilt. Kutílek claimed that at the time of their capture, the highest possible punishment was 25 years, in addition, trying to confuse the court experts with Kott. The request failed, and both men were sentenced to life in 1995.

On the night of May 2, 1990, both arrived in Nýřany in a Tatra 613 limousine. Disguised as police officers, they visited a guard named Frantisek Korbel, claiming that they wanted to perform a routine check on his weapon. When he handed them the weapon and they tried to seize it on the basis of a document controversy, he accused them of not being real police officers. So Kott shot him in the head. A witness described the two men: one in civilian and the other in a police uniform.

Kott and Kutílek met in 1988 at the Minkovice prison. Kott promised Kutílek that he would show him how to make money through murder. Both men left prison in 1990 on the basis of amnesties by President Václav Havel - Kutílek being released on January 6, and Kott on March 1.

Josef Kott (born 7 December 1957 in Rakovník) and Michael Kutílek (23 February 1951 in Prague – 15 March 2017) were a pair of Czech spree killers who, in the course of 26 hours, murdered four people and injured one (one of the victims was murdered before the spree). Both were later sentenced to life imprisonment. The two men are considered the first spree killers in the history of the post-communist Czech Republic. Three of these killings were committed just as the death penalty was abolished in the country on May 2, 1990.
