In the Czech Republic, Kajínek's case has become common knowledge and public discourse has emerged debating his guilt.

[3] In 1985, he was sentenced for theft from apartments, illegal holding of weapons and an assault on a public servant, as during arrest he injured two policemen using his hands and shoved another down a flight of stairs.

[6] These acts included illegal holding of weapons, such as sub-machine guns, pistols, with and without silencers, shotguns and a large quantity of ammunition and empty magazines.

[7] According to the courts ruling, Kajínek was found guilty of killing businessman Štefan Janda and his bodyguard Julián Pokoš in Plzeň, close to the Klatovská třída and České Údolí road intersection, while they were driving a vehicle on 30 May 1993, around 8:15 pm.

During this, Kajínek shot at least 12 times, also heavily wounding Vojtěch Pokoš, another bodyguard of Janda, who survived and became the cases primary witness.

[9] The case proceedings took 46 days in court and the process, due to being delayed multiple times, almost 6 years.

He was caught the same day after a guard of the prison chased him, though the exact chain of events that took place remains disputed.

[15] On 8 December 2000, Kajínek was caught by the Rapid Response Unit in the apartment of convicted murderer Ludvík Černý, a member of the Orlík killers.

[18] A smaller part of the public holds the belief that Kajínek was a victim of a conspiracy, such as him not being the true murderer.

[34] Kajínek lives with his wife in Brno-Bystrc and because of large media attention to his court case has become a national celebrity.

2000 – Marek Blahuš released the computer game Hlídej si svého Kajínka (Watch your Kajínek).
