The investigators of the crime of Roberto Eduardo Wolfenson, the 71-year-old electronic engineer murdered last Friday in the La Delfina country of the Buenos Aires district of Pilar, found today in the victim's house a roll of tanza compatible with the one that could have been used , according to the autopsy performed on the body, to commit the strangulation of the victim, reported judicial sources and the lawyer representing the dead man's children.
The procedure was led by the prosecutor in the case, Germán Camafreita, who was alerted this morning by Wolfenson's widow who found in the laundry area a roll of tanza, a type of fine nylon cable usually used in fishing, and also said that he couldn't find the latex gloves that the maid put on to clean the house.
The woman explained to the prosecutor that the transparent bag was inside a cupboard and that seemed "strange" since her husband was very tidy and would not have left it there.
Faced with this situation, the prosecutor immediately went to the house on lot 397 of La Delfina and, accompanied by personnel from the Scientific Police, seized the 100-meter roll of "Tanza pure nylon - Gaetani Hnos", according to the circular container. which, now, will be analyzed to try to establish if the murderer used a piece of that cable to murder the electronic engineer.
Tomás Farini Duggan, the lawyer who represents the two children that Wolfenson had with his first wife and who were presented as private victims in the file, considered that the missing latex gloves may be related to the fact that the person who used the rope He could have put on gloves to avoid cutting himself, "since that type of cable is very thin."
On the other hand, the widow also told the investigators that she also could not find a speaker and a pillow, which could have been stolen by the murderer.
The robbery was not the main line of investigation because the only thing supposedly missing from the house was Wolfenson's Motorola cell phone, nothing was mixed up and there was a safe with money and other valuables that were left intact.
However, judicial and police spokesmen confirmed that "for now no hypothesis has been ruled out, including that of a robbery."
Meanwhile, last Monday, in his first visit to the house where the murder occurred three days before, prosecutor Camafreita not only met for the first time with the victim's wife, but also seized two computers that will now be analyzed. by computer forensic experts.
"It is a personal notebook and another one from an international company for which he worked. We want to know if we find any clues among his emails, documents or any other type of information," one of the judicial sources consulted explained to Télam.
In turn, the spokespersons confirmed that another element that was sent for analysis, although to a different type of laboratory, is a long hair that, due to its length and morphology, did not belong to the victim and that was found, according to some sources, on the pants. from the electronic engineer specializing in lithium batteries.
Furthermore, already confirmed by his defense injuries that Wolfenson fought with his murderer while he was beaten and strangled, the subungual swabs taken from the victim's hands were also sent to genetic laboratories, given the possibility that he managed to scratch his murderer and that the murderer's DNA was left under his nails.
Yesterday, the prosecutor received the autopsy protocol signed by doctor Silvina Aguirre of the Forensic Medical Corps of the Scientific Police of San Isidro, which confirmed that Wolfenson had a violent death and that he died from asphyxiation in a strangulation maneuver using a rope with an element. very fine that left several marks on his neck.
At first, the San Isidro Scientific Police doctor Marcelo Rodrigué, who arrived at the scene shortly after the family's complaint was received, said that the engineer's death had occurred due to a heart attack, and He discarded the crime hypothesis.
?No one who sees that scene would think that this death occurred due to a heart attack.
I saw the photos, I am not a doctor, but it is clear that due to the large amount of blood and the injuries that are observed, at least I should have ruled a doubtful death? Lawyer Farini Duggan told Télam today.
?We have to investigate why this doctor said that Wolfenson died of a heart attack.
Whether it was due to incompetence or something else is a matter of investigation.
Do we need a clearer explanation from him?, she added.
The injuries described by the autopsy doctor are several thin strangulation grooves, as if there had been a "tug of war", and defense injuries, which are also compatible with the victim struggling and trying to loosen the noose with which he was being strangled.
For this reason, they found some marks and linear cuts on the palm and on the pads and phalanges of four of the fingers of his left hand that indicate that he tried to remove the cord or thread with which they compressed his neck.
But several other injuries were also found: a 7-centimeter cut on the back of the head that is being investigated if it was caused by the thin rope that strangled him or with another element and blows to an eyebrow, forehead, cheekbone, nose and mouth. , which caused a cut on the inside of one of his cheeks.
The date of death - always approximate in forensic matters and awaiting complementary studies - was estimated between 18 and 24 hours prior to the autopsy that was performed at 1 p.m. on Saturday the 24th of this month, which leads the clock to The crime occurred between 1:00 p.m. and 7:00 p.m. on the same Friday the 23rd in which he was found murdered.
But since the discovery of the body was at 5 p.m., the time slot to be investigated was limited by the prosecutor to between 1 p.m. and 5 p.m. that Friday.
Wolfenson was dressed the same way the maid described him when she saw him last Thursday, wearing an orange sweater, blue jogging pants, and a pair of Crocs that were resting on his legs.
There is still no motive or clearly identified suspect and, for the moment, the prosecutor has everyone under investigation: family members, close friends and employees.
The widow, one of the children, the maid, the gardener, the pool boy and the piano teacher who entered the house and found the body have already testified.
Wolfenson (71) had asked his employee on Thursday to clean because he was going to receive "visitors", but lawyer Farini Duggan said that this comment could have been due to the fact that one of his children was going to see him over the weekend. And furthermore, the investigations have already established that no person entered the La Delfina country with Wolfenson's authorization.
According to what they were able to reconstruct, Wolfenson spent a few days alone last week in his home in the country, since his wife had gone on a trip with friends and when he returned he did not return home, but went to his daughter's house. in the Buenos Aires neighborhood of Villa Devoto.
His body was found last Friday by the piano teacher who arrived at 5 p.m. for his usual class and when he notified the guard that no one was answering, he entered through a door that was open to the house and found the body in a guest room. .
