Charlie Kirk shooting criminal hunt included a rare forensic tech tip

It also revealed the search for the murderer of conservative political activist Charlie Kirk, With the suspect, it was determined on Friday as Tyler RobinsonLaw enforcement analysis of every possible progress. One part of the evidence they entered: print the forearm taken from the sniper position.

Before Robinson’s fear on Friday morning as a result of very humanitarian methods – it was reported that Robinson presented what might be a form of recognition of family members, who then participated in the information, which led to his surrender, although the situation is fluid and more Details about the investigation It was presented during the weekend – FBI’s Undersecretary, Robert Bouhels, said that the investigators had collected “the impression of the shoes, the printing of palm trees and helped” from the crime scene for analysis.

Princesses are not a common evidence, according to experts spoke with CNBC.

“It is very unusual,” said Patrick Maccine, a Texas -based criminal defense lawyer and retired Marine Corps Judge. McLean explained that the forearm printing is usually mentioned, the authorities collected the DNA or other skin residue from the surface that was pressed on the forearm.

Jeff Winnger, founder and CEO of “Enfather”, said it was just a fabric that was left to stay in the shooting position with a lower with the forearms on the deck for a period of time. “

We can use the forearm printing to confirm identification purposes, such as unique properties such as scars or a well -known clothes.

“Like fingerprints, the printing of the forearm can be unique enough to determine it if it is of sufficient quality,” he said.

It can also have a criminal value if a biological substance such as sweat, body oils or touch acid can be recovered, in addition to other evidence, it can confirm or contradict witnesses or video clips.

New technology gives the forearm a wider window in a possible suspect. Weninger said that material impressions have been used in criminal investigations for years, but in recent years, methodologies for identifying and comparing signs have developed specific meaning, and the scanning technique has improved to the extent that it “looks new”.

The 3D Scanning revolutionized this science, as it turned the forearm printing into a tank of previously not used information. Only factors such as race and sex cannot be determined, and investigators will continue to depend on whether the DNA or other biological evidence of the fingerprint has been obtained.

“It is a newer exploration in forensic medicine, including other prints of the skin. But it is not like printing a 100 % unique finger/palm/palm.

According to Braun, you will not distort the forearm printing a person from a database like a fingerprint. “Print the forearm is not a basic form of criminal evidence in the same way as the fingerprint imprint,” he said.

Print the forearm is not an essential form of evidence because there may be ambiguity, according to Bron. For example, while friction hills on the fingers and palm trees are unique for each individual, the skin on the forearm does not have the same detailed, permanent and individual styles.

The difficulty in the residues of the forearm is that even in prominent cases, any DNA will take some time to get results, and that if the person is not in a known database, it will not be useful until there is an arrest. “There will be many people on the roof of the building,” Malikin said. “But it is not like a fingerprint, there is no unique structure to help everyone.”

According to Clean, there were cases of experiences with forearm prints if there was something unique, such as tattoos or scars, “but I have never done any of these cases; they are definitely unusual.”

As in any hunt, in the hours that followed the shooting, the focus was on finding the shooter and arresting it. “Additional evidence will be developed on the strongest possible case later as the investigation continues,” said Brown. “But this was developed with the progress of the case,” he added.

Dan Gerale, the founder and administrative lawyer in the next law, says that in order to raise the “pattern” of the forearm as a guide, the issue had to apply sufficient pressure on a receptive surface area and that prints are more useful as support instead of primary, such as support for an inspection request for additional evidence.

“Under certain circumstances, forearm prints can also be acceptable in court. Like all scientific evidence, forearm prints must be accepted through the expert’s qualifying testimony, and the court tests are passed for reliability.” He added that this type of criminal evidence is likely to face more procedural obstacles to abandon it before accepting it in the trial.

Robinson was arrested on suspicion of heavily murder, a firearm felony, and an obstruction of justice by the police. Prosecutors will eventually decide the charges he faces before the court, which is expected to be submitted on Tuesday.

In the end, Tyler Robinson’s arrest came to human ties instead of criminal relations, and some criminal experts say that the distinctive advantage of the recent political violence is the primary desire of the murderer to arrest her instead of carefully planning and evading her arrest.

Braiana Fox, a former special agent for the Federal Investigation Office and a professor of criminology at the University of South Florida, says progress in crime technology was noticeable over the past two decades, and some criminals may not be aware of the forensic medicine available for law enforcement. “Maybe he has thought, oh, I can leave the forearms prints and will not reach anything,” said Fox.

But she believes another mentality may have been at work. Compared to the case of Robinson in the case of Luigi Mangion, which was associated with a United Health Care Officer last year, Fox believes that criminals who lead ideological may be interested in sending a more message than escaping from the consequences of their crimes.

This means that they may not think about the path of evidence that they leave behind as much as some other criminals ignore, whether they are publications, cover their face, or how they get rid of a weapon. “Attention helps to give more oxygen to what an ideology wants to say,” Fox said. She added, “Somehow, they stipulate the fact that they will be arrested and there is nothing wrong with leaving some evidence. They do not want to arrest immediately, but their main task is to achieve the goal, which is to kill their goal.”
