A crime has been written and technology has helped solve it

In cases like that of Diana Quer, some companies help the State unselfishly to find the keys to the event on a computer level

           When a crime is committed, the investigators of the Civil Guard or the Police take action. They collect evidence, analyze the place of events, tie loose ends, trace psychological profiles and, increasingly, use new technologies to compose the pieces of the puzzle and solve the mystery. We have spoken with some of the companies that collaborate with the state's security forces and bodies to solve some of these crimes.

        In a group of suspects, investigators can discard some of them (or verify their suspicions) if the coordinates of their mobile phones are located near the crime scene. To do this - and with prior judicial authorization - the telephony operators can verify if the suspects' mobile phones are located at certain coordinates.

Thanks to the triangulation of mobile phone antennas or GPS position signals that emit smartphones, this inflammation is increasingly easy to achieve.

However, on other occasions, investigators must ask for help from companies or specialists in certain areas to help them resolve certain crimes.


These aids and collaborations are very broad and diverse. They can range from the forensic analysis of a hard drive to issues of cybersecurity through very technical and specific issues in certain areas.

From training to help

      The security bodies of the State have, increasingly, computer professionals and technicians who have the training to investigate the aspects related to the new technologies of some crimes.

        On occasion, some of these specialist companies are also engaged in training these technicians from the security forces. This is the case of Secur�zame. Its CEO, Lorenzo Mart�nez, explains to Innova + that his company has collaborated several times providing training and security elements in cybersecurity "in order to help improve their skills from a technical point of view, in order to be more efficient in their job".


Confidential information

There are many and varied companies that collaborate with different agencies and bodies in the resolution of technical crime issues. But it is not easy to know the details of these works.

Even on occasion, many of these companies must sign confidentiality agreements with those who agree not to give information about these collaborations and grants, either in specific cases or as part of a broader alliance.

In addition, taking into account the nature of some of these events (especially those related to computer security) it is almost a matter of state security that absolutely no details are leaked about these secret operations.

Another of these companies that trains these bodies is Engineering and Road Safety, specialized in the resolution of traffic accidents and that was vital to identify the vehicle of the alleged killer of Diana Quer. Marcos U. P�rez is one of its founders.

�We give training to the Police and experts. Sometimes they simply ask us for technical help on very specific issues and advise them in certain cases. "

They have helped, for example, the Prosecutor's Office of Salamanca, the Court of violence against women in A Coru�a, the municipal police of Vigo, the Valencia or Gand�a localities, the Ertzaina and its judicial police, Guardia Civil ... �The collaboration It is technical in many cases.


They pose a problem that does not necessarily have to know what corresponds to have a different approach. On many occasions, there is no economic compensation. Only if it is more than a simple advice is when you hire the services of this company.

Normally, these technical questions are from a very specific part of an investigation and are presented in an aseptic manner so that they do not affect or compromise the rest of the case. So much so that although the work of this company was crucial to locate the vehicle of the alleged culprit, they did not know that they were working in that case.


�They arrived with some images of traffic control and wanted to identify what was seen. We did not know anything until we had to go to the place where they were recorded to take more data �, explains Marcos P�rez. "Neither do we ask anything about the cases, the reasons can be very varied."

When there is a professional collaboration, Secur�zame recognizes that it has received a financial compensation for the training carried out. "It is still a response service that meets the specific needs of a company and that is contracted, in this case, by a government organization."

Mart�nez, however, clarifies that this training is "something that we often provide to different private companies, it is not specific to the State's security forces".
