Early in the morning of December 2, 2001 Helena YuvaniThe 27-year-old, high on benzodiazepines, was thrown unconscious and half-naked from the roof of a four-storey building in Sabadell. His body was found by a housemate the next morning. This is the story of one murder case who has been rushing from one suspect to another for 23 years, but has achieved nothing. However, it has recently been rediscovered to use DNA analysis techniques that have improved over time. Thanks to this, out of all the possible suspects, there is now one whose likelihood of being the culprit has increased significantly.
It is true that DNA tests cannot 100% confirm that he is the killer of Elena Juvani. However, this discovery opens a new thread. Attention should be focused on the suspect, who was initially given much less importance than other candidates.
The case has been reopened and police are investigating the events. new tracks. Perhaps Elena Yuvani’s family can finally breathe, knowing that their daughter’s killer is still not at large.
The mysterious murder of Elena Juvani
In fact, the murder case of Helena Yuvani began two months before mysterious people threw her from the roof.
It all started in September, when a young woman came home and found a bottle horchata and some pastriesalong with a mysterious note that no one signed. Horchata was Juvani’s favorite drink, so it’s clear that the person who wrote it knew this.
A month later there was a new gift. This time, juice bottle with another note. It is unknown whether he used horchata in the first note. However, she drank the juice, although she soon felt ill and put it aside without finishing it. Intrigued, she took the remains of the drink to a laboratory in Sabadell, where she was told it contained benzodiazepines. Were they trying to drug her?
The notes mentioned Excursion University of Sabadell (UES)where the young woman often went hiking. It seemed as if one of his companions (or several, since they spoke in the plural) was trying to play a joke on him. However, he was not afraid. Rather, according to those close to him, he was curious.
But on November 30, things went wrong. The girl went to work, but never reached my position. The next day, her father arranged to meet her, but did not show up. She also did not go on a date with her friend on December 2. Concerned, Elena Yuvana’s father called her at work, where he was told that she did not show up for work on the 30th. Faced with this disturbing news, he decided to file a report, which helped police identify the body that a resident of a house in Sabadell had found just hours earlier. The head was so damaged when it fell from the roof that it could not be identified before.
Who threw it?
Soon the police connected the building where the crime took place with the place where Helena Juvani was. He lived on the third floor Montse Carriagefellow excursionist to the UES.
He did not have a firm alibi as to why he was not home that night, although Helena’s clothes were found on the terrace. The first handwriting analysis showed that she could be the author of one of the notes. Based on this information, she was arrested. Later, when analyzing his apartment, it was discovered a bottle of benzodiazepines and some matches. The victim had burns on his body that could have been caused by matches. She was sent to prison, although other suspects continued to be studied.
two of them were Santi LaiglesiaCareta partner and EEC member, and Anna Echagivelanother tourist whose handwriting was associated with the second note.
Both were sent to preventive detention, but were later released due to lack of evidence. Monse Carriage continued to remain in prison, where he committed suicide 3 months later. He always insisted on his innocence.
Another suspect in the murder of Elena Zhuvani
A fourth suspect has emerged in the investigation into the murder of Elena Zhuvana. Another EEC member named Javi Jimenez.
This was considered suspicious for three reasons. Firstly, because Elena herself told her friend that she suspected that he was the author of the letters. On the other hand, because he had a possible motive. In love with her, he asked her out but she rejected him, causing a big rift between them. But above all, it was considered suspicious because it was clearly He lied in his alibi.
Several colleagues from RAO UES were questioned after the murder. Jimenez claimed that on the night of the crime, he and a colleague from RAO UES were organizing a tour at the headquarters for the next day. This comrade was Jaume Sanllehiwho, on the contrary, reported that he drank some beer with friends in Barcelona.
Once the two friends were able to talk to each other, they must have realized the discrepancy, because Sanley returned to the police station to change his statement and say that he had made a mistake and that he had in fact been with Jimenez that night. crimes. However, one of his friends from Barcelona insisted that Jaume drank beer with him. Jimenez I lied.
DNA that connects the puzzle pieces together
Traces of DNA were found on Helena Juvani’s clothing and body. However, although forensic science was already advanced enough to analyze this type of specimen in 2001, it was not as advanced as it is today. It was not possible to get any response from them.
Since then, significant progress has been made, especially in relation to sequencing and haplotype analysis. Therefore, given the pressure from the families of Juvani and Kareta, it was decided to reopen the case and use new methods.
The DNA belongs to a man, so at this point only the suspects remain. Javi Jimenez and Santi Laiglesia. For this reason, DNA samples were taken from him to compare them with the DNA found on the body.
This was done using two types of forensic testing. On the one hand, analysis of Y-chromosome haplotypes. These are groups of genetic variants that are inherited together on the same chromosome. They are usually used to study biogeographic origin humans, since some of them are conserved and tend to be the same among people from specific geographic areas. These haplotypes can match between multiple people, but can be used to reset.
In the case of Helena Juvani’s murder, the Y-chromosome haplotypes of the samples match the DNA of Laiglesia. This indicates that it cannot be ruled out that he is the killer. On the other hand, discrepancies with Jimenez’s DNA indicate that it is. can be discarded.
The second test performed was the autosomal microsatellite (STR) test. These markers are elements consisting of simple DNA sequences of 1–6 letter (base) pairs that are repeated in tandem. The number of repeating segments in one of these sequences may vary between individuals, so this may also be a good way identify DNA. Using this test, it was concluded that Laiglesia and three other people were 24 times more likely to contribute the DNA mixture located on Helena Jubani’s sweater than four strangers from the population.
RPG gone wrong
Santi Laiglesia has many genetic candidates to be Helena Juvani’s killer, as many relatives and some police officers have suspected for years. We can’t know with 100% certainty, but there are many reasons to take his statement one more time and delve into what may have happened that night.
Apparently, Elena was kidnapped for two days, during which she was drugged and tortured. This, added to the letters, leads to the suspicion that It could have been some kind of role-playing game.. Who were the culprits? More research is needed, but DNA testing may provide many more clues than it did then.
