Los Angeles police arrest bike-borne face-slasherSITUATION

Los Angeles police have arrested a 19-year-old teenager on Wednesday on the suspicion of him being the “slasher” who has been cutting the faces of at least nine people. All his victims seem to be chosen at random, while he rode through the city on a bicycle.

Police said the man was detained on suspicion of attempted murder. The Police tracked him down to a homeless encampment after his parole officer recognized him from security camera images published in the media.

A spokesman for the Los Angeles police was not immediately available for comment early on Thursday. The string of attacks began on March 20, according to the LAPD, with victims aged from 13 to 85 years old. The suspect struck in broad daylight.

The latest two attacks occurred on Monday when officers responding to a radio call at around 8:40 p.m. found a man suffering from a severe wound to the left side of his face. About 15 minutes later, a young woman was attacked nearby.

“He just came in back of me and hit me,” Stefany Coboz said, displaying a stitched and bandaged wound in her neck that she said would leave permanent scarring. “I just started looking at him, he looked back, I grabbed myself full of blood.Coboz said her assailant did not speak to her but laughed as he rode away.


This is yet another case which is termed as ‘difficult’ to solve as there is no obvious motive to these attacks. Thus, it is not only difficult to trace the attacker. But, it is also all the more important to quickly solve this case and put the perpetrator behind bars, because he or she is extremely dangerous owing to his or her being untraceable and unpredictable.

At the same time, the police need to be careful to not get an innocent person punished. The person who has been arrested may or may not have been the perpetrator. How can the police and the investigative agencies be undeniably sure that he is or is not the ‘slasher’.

The run-of-the-mill approach is to thoroughly and lengthily interrogate the suspect, investigate and turn his life upside down. This causes intense trauma to the person under test. God forbid if he or she is not the culprit, then such an invasion of privacy can leave the person transformed if not traumatized.

Is it possible to determine if a person has knowledge of the details about a crime, which only the perpetrator, planner or a witness could possess? Can this determination method be accurate and consistent in its findings, yet quick? Can it be quick enough so that a large number of suspects can be screened? Can it have assembly line-like efficiency without de-humanizing the test subjects? Can such a determination method be free of torture?

Can it be thoroughly objective and not depend on the subjective opinions of the test administrator, unlike a lie-detector test?

Even if such a method fulfils all the above criteria, can it be more inexpensive than existing methods overall? If it is not more cost-effective, not resource-effective and less-time consuming, then it is liable to be rejected as an investigation and interrogation method.

If such a method is present, then it is nothing short of a revolution, a disruption in the entire investigative and interrogative domain.


iCognative is a breakthrough technology augments investigation and interrogation techniques in use. It is surprising that although DNA and fingerprinting are popular and considered to be decisive tools in investigations, they are uncovered in only 1-2% of all cases. To add to this, they are extremely costly, labor-intensive and time-consuming to gather, preserve and process. This adds to delays and inefficiencies in the judicial process. iCognative is applicable to 85-90% of all civil and criminal cases.

iCognative has been introduced by Massachusetts based company Brainwave Science can help to solve cases related to human and drug trafficking. Surprisingly it is also equally capable of helping in the investigation and interrogation in criminal domains such as cybercrime, law-enforcement,  national-security, border-security, immigration, and counter-terrorism.

If compared to traditional techniques, iCognative is highly accurate, to a degree more than 99%.

Not only that, it is extremely accurate and reliable. This is just the thing that law enforcement and investigative agencies are looking for. Besides that, iCognative is highly-customizable, easy to teach, cost-effective, provides immediate results, and requires significantly less manpower. The test subject is not put through any torture if he or she is interrogated using the iCognative process. In fact, he or she barely needs to exchange any words with the test administrator. The interrogation process takes place using a specialized headset and a computer system which runs the iCognative system. The testee is shown images, words or phrases related to the crime or the criminal organization under investigation. At the same time, the brain responses to each stimulus are recorded and transmitted to the computer system where these are analyzed by the iCognative software. iCognative technology can tell whether the information shown to the suspect was already known by him or her or not. This knowledge is extremely important in identifying culprits and exonerating innocents.

In this case, the arrested teenager can be put through the non-invasive iCognative test. This will be to determine if he really has crime-specific information present in his brain or not. Because iCognative is really objective and accurate, if the system says that that the suspect has never seen crime-related stimuli ever before, there is very strong reason to believe that he is not the likely perpetrator. The stimuli which he will be exposed to can be pictures/details/ time-stamps/location-markers of all the places which the suspect has been in around the time of the incidents. They can also include the locations and times of all the slashings which happened. It can help determine if the suspect was there or has any awareness of that crimes and locales at all. Moreover, descriptions of the victims, their appearances, their clothing, their locations, the times are something which the criminal is likely to have embedded into their brain. The same can be used as stimuli in a test to screen an innocent from a likely suspect.

Not only can the presence of crime-related information be indicated by iCognative software, but his or her ties with other criminals and gangs can also be discovered using this technology. If the suspect is suspected to have been radicalized, then the same can also be tested using this technology.

iCognative is not a limited technology. Since it can check for the presence of any kind of specific crime-related information in the mind of the test subject, the possibilities are endless.

Los Angeles investigative agencies must use the incredible power of iCognative, provided by Brainwave Science to exonerate the innocent and put the guilty behind bars as soon as possible.
