Charlie Kirk, shooting from criminal hunting

As the search unfolds for the killer of the conservative political activist Charlie Kirk, With a suspect identified on Friday as Tyler RobinsonLaw enforcement bodies have smashed all possible benefits. One evidence they entered on: forearms, taken from the Sniper position.

Before overcoming Robinson’s fear on Friday morning, as a result of very human methods – it was reported that Robinson suggested that he may have been a form of recognition by a family member, which was then shared by the information that led to his surrender – FBI Bolsa’s agent said that investigators had gathered.

According to CNBC experts, the forearm prints are not generally collected.

“This is very unusual,” said Patrick McClein, a Texas prosecutor for criminal defense and a military judge of the Marines. McClein explained that, as a rule, when the forearm printing was mentioned, the authorities were collecting DNA or other skin residues from the surface on which the forearm was pressed.

“It’s just mold from prints left out of the prone shooting with the forearm on the deck for a certain time,” said Jeff Veninger, founder and CEO of law enforcement consultants who cooperated with the LAPD elite division and with a secret service. “It would be like the shoes or the print they raise,” he added.

Wenninger says that forearm, such as unique characteristics such as scars or a imprint of known clothing, can be used to confirm the identification targets.

“Like fingerprints, the forearm seal can be unique enough to identify if it is sufficient,” he said.

It can also have a forensic value if you can restore biological material such as sweat, body alleys or DNA touch, and with other evidence, it can confirm or contradict witnesses or video materials.

The new technology gives the forearm a wider window in a possible suspect. Veninger said physical impressions used in court studies, but in recent years the methodology of detecting and comparing specific significant markings has developed, and scanning technology for prints has improved so much that “it seems new”.

3D -improvement made a revolution in this science, turning the forearm into the reservoir previously unused information. One imprint cannot determine factors such as ethnic affiliation and gender, and investigators will still depend on whether DNA or other biological data have been obtained.

“This is a newer study of forensics, including other skin prints. But it is not like printing/palm prints, which is 100% unique,” said Toby Brown, CEO and founder of the American special investigation specializing in the protection of the executive, monitoring threats and complex studies.

According to Bruna, the printing of the forearm cannot determine the person from the database as the imprint of the fingers. “The press of the forearm is not considered the main form of forensic examination in the same way as the imprint of the fingers,” he said.

According to Brown, the press of the forearm is not the main form of evidence as there may be ambiguity. For example, while the ridges of friction on the fingers and palms are unique to each person, the skin on the forearm does not have the same detailed, permanent and individualized samples of the ridge.

Difficulty with the remains of the forearm is that even in the loudest cases, any DNA will take some time to get the results, and if a person is not in a known database, it will not be profitable until the arrest is arrested. “There will be no too many people on the roof of the building,” said McClain. “But this is not like the imprint of the fingers; there is no unique structure for everyone’s forearm.”

According to MCCLAIN, there were cases that coped with the prints of the forearm, if there is something unique, such as tattoo or scars, but I never did none of these cases; They are definitely unusual, ”he said.

As in any section, hours after shooting, the focus was on the search for shooters and arrest. “Additional evidence of the strongest opportunity will be developed afterwards, as the investigation is ongoing,” Brown said, adding that the authorities need a probable reason for arrest, and evidence that is not reasonable are in the lawsuit. “But this is developed as the case is promoted,” he added.

Dan Gerl, the founder and head of the lawyer under the following law, says that for the “sample” of the forearm, which will be lifted or photographed as evidence, the subject would have to put sufficient pressure on the susceptible surface area and that engravings are most useful as support, not primary, such as support.

“Under certain circumstances, the forearm prints can also be admitted in court. Like all scientific evidence, the forearm prints must be allowed according to the testimony of a qualified expert and pass the court tests for reliability,” said Gerl. This type of forensic evidence is likely to face more procedural obstacles before taking the trial, he added.

Robinson was arrested on suspicion of exacerbation of murder, a crime of discharge with firearms and justice in the police. The prosecutor’s office will eventually resolve the allegations that he is facing the trial, which is expected to be filed on Tuesday.

In the end, Tyler’s arrest was reduced to human rather than judicial communication, and some criminal experts say that the determining feature of recent political violence is the main desire of the killer rather than plan carefully and shy away.

Brian Fox, a former special FBI agent and a criminology professor at the University of Southern Florida, says that over the past two decades the progress in crime technology has been characteristic, and some criminals may not know about the level of forensic examination. “He may have thought, ‘Oh, I can leave his forearm prints, and nothing will be,” Fox said.

But she believes that another thinking may be at work. Comparing Robinson’s case with the case of Luigi Mangion, who encroached on the joint healthcare manager last year, Fox believes that ideologically conditioned by the criminal can take care of sending a message than the consequences of escape for his crimes.

This means that they may not think about the trace of the evidence they leave behind, like some other criminals, whether it is engravings, covering their face or how they dispose of weapons. “Attention helps to give more oxygen what the ideologist wants to say,” Fox said. “In a sense, they are peculiar to the fact that they will be caught and okay, leaving some evidence. They do not want to get immediately, but their main mission is to achieve the goal that is to kill their goals,” she added.
