The investigation into the crime of Juan Miguel Isla -the businessman found in a well in Manzanares last March eight months after his disappearance- has added a new element to the investigations that has baffled the industrial environment.

This is the brother of the deceased, Francisco, about whom the Central Operating Unit (UCO) of the Civil Guard has serious suspicions, although his connection to the events is still unknown to the agents.

Two people are in prison for Isla's death: Antonio Caba, the man who mediated the sale of the farm that the businessman closed hours before he died and who had been investigated years before in connection with the disappearance of another industrialist, and a friend of yours.

Francisco Isla is now joining the wheel of the elite Civil Guard after confessing that Caba gave him a pistol one day after his brother's disappearance so that he could keep it for himself..

According to his own testimony, collected in the summary, he did not ask anything and hid it in a ship he owned, under a sink. The gun was not registered.

Two weeks after the UCO found the body in a well owned by Caba, he told the investigators. The Isla brothers had been at odds for years after the death of their father and the distribution of the family inheritance.

“Last year Caba gave me a gun. I'm not sure if it was before or after the murder,” Francisco told the agents when he appeared before them with his lawyer..

Before delivering it, he sent a message to his relatives to notify them of what he was going to do, collects the summary. When asked why he did not notify the existence of the weapon until March 27, 2023 -his brother disappeared in July 202-, Francisco Isla delayed his interlocutors. He assured them that “until Antonio Caba was arrested, he did not believe that he was responsible for the murder of his brother Juan Miguel and, therefore, that the weapon delivered could be related to the facts.”

Investigators are now working to determine if the gun that Francisco Isla was keeping is related to the crime since it has not yet been determined exactly how Juan Miguel Isla died in the absence of a definitive autopsy report..

The agents stop at how Francisco Isla and Antonio Caba, who had a very good relationship as revealed by the police investigation in several of its phases, were “up to date” with the progress or news of the investigations and insist that the indications what is on the table “beyond mere conjecture.”

Thus, they intercept several telephone conversations between the two. The first of these occurs a few weeks after the disappearance. The summer of 2022 was not over yet.

Francisco Isla: Every day I am more convinced, he has taken the rooms and has said: stay there, fuck you.

Antonio Caba: Who knows what I have out there abroad or what do I know, I don't know what to think. We do not know anything? I haven't asked you, but when you haven't told me anything…. I haven't asked you, but when you haven't told me anything.

FI: What are we going to know? He'll be out there with whores, he'll have gotten involved with some…

AC: Well, that's what it gives me, that's what it gives me and the feeling, but now, now, now, now…

Investigators from the Central Operative Unit of the Civil Guard incorporate another telephone dialogue between Antonio Caba and a friend of his named Pepe in which they launch their theories about what could have happened to the disappeared businessman and name his brother Francisco. They talk about, the summary of the case exposes, “various aspects of the event, even ironic at their possible involvement not only in the murder of Isla.”

Pepe: This Isla couldn't have been murdered by his brother, right?

Antonio Caba: You too…. Yes, you said those things on the phone, masters, don't fuck with me.

P: It's that he doesn't worry, I don't see him worried.

AC: Well, what do I know, man, but no, don't bother me. What a thing you say to me (laughs).

Q: Right now you are worried about whether they are listening to us.

Antonio Caba was the last person to see Juan Miguel Isla last July when he received, through his services, 50,000 euros from the sale of a family farm valued at more than one million.

He was also the last one to be with another industrialist, Jesús María González Borrajo, in the summer of 2019.. He helped him sell two high-end cars and nothing was known about his whereabouts. The businessman disappeared on July 21, 2022 after meeting Antonio Caba.

At the end of last January, the Civil Guard located the businessman's car in an open field in Albacete. It was a neighbor who gave the notice after recognizing the vehicle after spreading, days before, the investigators some images of the vehicle in search of citizen collaboration.

Agents of the Central Team of Ocular Inspections (ECIO) of the Criminalistics Service of the Armed Institute, have been analyzing it for weeks in search of clues.. After the discovery of the car, the search was intensified. A reconstruction of the route between the point where the businessman disappeared and the open space where the car was found in Albacete was even carried out.

The clues collected led the agents to the well of that farm, which Caba had bought. Isla had traveled to Manzanares the afternoon before his disappearance from Playa de San Juan, in Alicante, where he lived with his wife to collect 50,000 euros in cash for a piece of land that he had just sold.

For this, he had the collaboration of Caba, who was the one who accompanied him. She had met him in La Solana. Later, his trail was lost until on March 14, the UCO located him in a well.

Bad family relationships have always been on the investigators' table although, for the moment, the degree of involvement of the deceased businessman's brother remains to be determined.. For their part, the other two involved remain in jail for the crime of Juan Miguel Isla.
