Mr. Alec Jeffreys, a British geneticist from Leicester University, is the first to use the DNA analysis method for criminalistic purposes in 1987. A fifteen-year old Linda Mann is found dead on the way from Narborough to Enderby on November 21th, 1983. She has been raped before her death. Some semen is found at the scene of crime. But the murderer escapes.
Three years later, a fifteen-year old Dawn Ashworth is found dead not far from the place where Linda Mann's dead body was found. She has been raped as well. A seventeen-year old doorkeeper working in an insane hospital pleads guilty. As both acts of murder are almost identical, that man is suspected of murdering Linda Mann too. But he denies murdering her. That is why police officers ask Mr. Alec Jeffreys to analyze the samples of the semina and the young man's blood. The result of the analysis surprises everybody. The samples of the semina and the blood do match. But the seventeen-year old young man is not the murderer and thus he is released from the custody.
Police officers keep on searching and they decide to get the blood samples from more than 4,500 men living in the neighbourhood. But the murderer is still not found. Seventeen months later, Police learns that a baker from Narborough, named Colin Pitchfork, has talked round a friend of his to have his blood taken instead of him. His blood sample is taken and the match is found. Colin Pitchfork pleads guilty and is sentenced to a twyfold life imprisonment.
On June 27th, 1990, at about 07:30 a. m., a nineteen-year old student, Jana Krkošková, is found dead in the toilet of the Masaryk College of Education, Brno. She is not difficult to identify. A bag containing her textbooks and her personal documents is found lying on the central heating body. Large blood stains are found on the floor and on the wall round the dead body. A different sort of blood stains is found on the particular part of the wall. Those stains seem to be made by shaking a bloodied hand. The murderer is possible to suffer an injury the attacking the girl with his knife. It is obvious that the murder has been sex-motivated. The general public is upset.
The autopsy proves thirty-one stab wounds in her chest, back and nates. She was still alive when being stabbed. A serious cutting wound is found in her loins. Any semen on her body is not proved. The victim tries to escape but the murderer keeps on attacking her. On and on. The girl is sure to suffer from a terrible pain before she dies.
Milan Lubas (26) is arrested in his girlfriend's flat the very next day. His right hand is tied round and he leaves the flat barefooted. He explains it like that: "I have come barefooted..." Lubas is not arrested by chance. He lives not far from the place where the policeman, investigating his previous crimes, lives.
In 1981, a teenage Milan Lubas sits in court for a criminal assault he committed with his uncles, a theft and a robbery. He is sentenced to spend two years and a half in prison. Shortly after having been released, in 1983, Lubas chooses a woman in a tram, spies on her to the place she lives and cuts her face with a cutthroat razor, but he does not kill her. A bystander disturbs him. The court finds Lubas to be a dangerous habitual offender and sentece him for a wilful bodily harm to spend six years and a half in prison. In January 1990, Lubas is released from prison under the authority of the President Act of Oblivion.
Lubas disclaims the charge of murdering the young student during the police investigations. But there is still the cutting wound on his palm. He insinsts on having hurt himself agains a metal plate on a countruction site. The medical examiners rule out such a machinery of his cutting wound. He changes his evidence saying he was hurt during a knifing, but he refuses to specify the place where he was attacked. His blood sample is obtained to be compared with the blood sample (like shaking a bloodied hand) found at the crime scene. His bloodied clothes are found during the house search (his jeans and a pair of his socks hidden in a clothes-basket filled with water and surfactant). The criminalists, seeing the results of blood-comparison, are disappointed - Lubas's blood is of the same group as his victim's blood... Lubas's solicitor asks for his client an immediate release and wants the Police to dismiss the case.
As there is a lots of variance, Lubas is sure to be the murderer and thus the criminalists ask the experts from the Genetics and Molecular Chemistry Institute, Science Faculty, the University of Bratislava, to carry out the blood samples DNA identification. Although they engage in DNA analysis method only in an experimental way there, Doc. RNDr. Vladimír Ferák, CSc., the executive director, and his co-workers decide to carry it out.
On October 24th, 1990 - nearly four months after the murder - the criminalists receive a three-page expertise report. The report says it was Milan Lubas who left his blood stains at ladies' in the Masaryk College of Education. The blood stains found on the Lubas's clothes are proved to be identical with the murdered Jana Krkošková blood sample...
Milan Lubas is sentenced to a twenty-three-year imprisonment. He commits suicide on February 4th, 1993. He insinuates murdering the student only once, when talking to a co-prisoner of his. He does so just to get some information about a usefull statement for the defence. He says he wanted to steal some things from the offices in the college. The doors should have been opened by his knife. He opened the toilet door by chance and he could see a bag lying on the central heating body. But Jana Krkošková's bag lying on the central heating body could be seen only by a person present at the scene of crime. By the way, the FAB cylinder-type lock is impossible to be opened with a knife...
St. Augustin Monastery is nearly 300 meters far from the college of education building. Johann Gregor Mendel experimented in a pea intercross in a small square-shaped garden there. He was the first man to formulate the ABC of genetics in 1865. He used to walk about the River Svratka bank where a murder will be committed 125 years later, And it will be the genetics to criminate the murder. It is good to see that the Czech criminology keeps up with the world...© Miloslav Jedlička, D. C. L.
