A method that is used by criminals and that in recent times was suffered by several Buenos Aires politicians served the Federal Police to establish the link between the Correntine journalist Griselda Blanco (44) and the businessman of the night who is accused of murdering her.
Through a "SIM swapping", that is, the cloning of the chip of the victim's phone that the murderer made disappear, the agents were able to reconstruct their WhatsApp conversations up to two days before the crime, and establish that they maintained a link that was strained because of some demands of the victim.
The judicial situation of Darío Alfredo Ricardo Holzweissig (46) is complicated. Although for now the prosecutor Maria José Barrero Sahagún charged her with the crime of simple homicide, in the coming weeks that classification would pass to that of femicide.

The journalist's children will become plaintiffs and will move forward with this proposal based on the clandestine relationship that united Blanco with Holzweissig.
The security cameras were also key to locate the businessman of the night in the vicinity of the victim's home. The footage revealed that the man left his home at 2.11am on May 20 aboard his wife's Suzuki Swift.
To get to Juan Pujol, where Blanco lived, Holzweissig used an illogical road and parked on another street, more than a block away. At 2.37, another image shows him walking, meters from Griselda's house. From there he left at 3.12 with a phone in his hand and the same bag with which he had arrived.
The man arrived home again at 3.35 – he used a faster path – and ten minutes later he was seen walking towards the field where on Friday morning a knife and a broken cell phone were found, identical to the one that disappeared from the journalist's house.
The cell phone they found in a vacant lot was the same as that of journalist Griselda Blanco (44), murdered in Curuzú Cuatiá, Corrientes.
At 4:02 a.m., he headed back to the vacant lot on the side of Route 126. "The camera only shows him walking to that place, but it does not capture what he does," said a source linked to the investigation.
The businessman was put on the radar of the Federal Police Homicide detectives by Griselda's children. They both knew about the bond and some problems they had had.
That's why Holzweissig's cell phone was seized, from which he had deleted the history of conversations with the victim. The feds were able to rescue much of the messages. The rest came from "SIM swapping", a very simple procedure that only needs a series of personal data of the victim to take possession of the SIM card and thus be able to access all the contents of the phone that, in this case, the murderer made disappear.
Blanco's children acknowledged that the destroyed device that appeared in the vacant lot is the same model and the same color as the one used by their mother. The experts could not access the IMEI (International Mobile Station Equipment Identity), which is the 15-digit code pre-recorded by the manufacturer to identify each mobile device worldwide. Each make and model has an identification code granted by the Global System Mobile Association.
"There are audios that the businessman sends him in which he is heard very nervous. There are things that are going to be preserved because it makes people's privacy, but they are quite clear. Also the request for money by the victim. One of those payments is documented by a bank transfer, but it is not clear if it was for advertising of the bowling alley or for some other reason," sources linked to the file said.

Prosecutor Barrero Sahagún was reached by the images of the security cameras and those messages to request the preventive of the businessman. The judge of Guarantees Matías Vega gave the reason.
The autopsy revealed that Griselda Blanco suffered a strong blow to the head and two punctures in the neck that did not injure important arteries.
The cause of death was strangulation with a rope that, you know, has male genetic material. The DNA could be known as early as this week.
In one of the woman's hands were found several hairs that she tore out of the murderer when he was fighting for his life. From the morphological analysis it emerged that they are identical to those of Holzweissig, but one of them had the bulb and in the prosecutor's office of Barrero Sahagún and the Federal Police are convinced that it will coincide with the genetic profile of the imprisoned businessman.
This DNA study will be carried out by the team led by biologist and geneticist Daniel Corach. With this scientific evidence, the siege on the entrepreneur would begin to close.
