DNA leads to arrest in mom’s 1977 cold case
May 2, 2018 | Brainwave Science
A cold case from 1977 now has a suspect arrested in custody. Officials in Los Angeles say DNA and fingerprint evidence collected at the scene of a brutal 1977 rape and murder of a woman in front of her two young sons has led to an arrest in the case.
The arrested suspect, Kenneth Ray Matthews, now 60, allegedly broke into the home of 25-year-old Leone Davis. She had just put her children, 4 and 7, to bed. Matthews is accused of stabbing the woman in the neck after he raped her. Her two boys were looking in at the moment of the crime.
The charges for Matthews are capital murder. Authorities are unable to file rape or robbery charges in the case because of statutes of limitations, according to a press release.
Prosecutors say a fingerprint match initially led police to Matthews, and a follow-up DNA test provided evidence he was at the crime scene. He was arrested last week. If he will be convicted of murder, Matthews could face the death penalty or life in prison without parole.
Cold cases are a sad reality throughout the globe. Law enforcement gets a large number of cold cases every year that are left unsolved due to a multitude of reasons. Sometimes there isn’t enough evidence for a conviction; other times, there is no DNA or witnesses get tampered with.
Law enforcement is constantly challenged to find a new way and new approaches to solving cold cases. More than often, the current investigative means at their disposal fail to deliver the expected results. In addition, they are time-consuming and expensive. Just think about the DNA test – it can only occur if DNA is present at the crime scene. The polygraph test is also prone to errors, as a lot of murderers have managed to pass it by in the past.
So how can law enforcement rise up to the challenge and solve this cold case and put the criminal behind bars?
Did you ever think that technology could advance so far as to rely on information stored in the human brain? iCognative developed by Brainwave Science is a state-of-the-art investigative tool that comes to aid law enforcement worldwide. Its use extends to Law Enforcement, Border Security, Counterterrorism, and Counterintelligence.
iCognative can distinguish innocents from suspects through a simple test case that is easy to conduct and time efficient. The system behind it doesn’t rely on human intervention, thus it’s not prone to human error. iCognative relies upon the information stored in a person’s brain – a place where events are stored even years after they occurred.
In the 1977 cold case, the technology can be of invaluable use in proving the guilt of Matthews. We can conduct a test, using him as a subject, but we can also conduct a test on any witness and any other person of interest, relevant to the case.
It takes only 15 minutes to build the iCognative test case for the subjects that will be tested. All the confidential information that only the investigative agent knows and that is relevant only to the suspect will be input into the system. Let’s consider everything we know so far from the media: the date of the crime – 1977, the exact location of the crime in Los Angeles, the murder weapon – a stabbing weapon, the 2 witnesses – the victim’s 2 sons, the objects where his fingerprints could be found and all the probes where his DNA evidence has been found at the crime scene. All this mentioned information will be used as stimuli in the test case, in the form of pictures or text, depending on their availability.
The stimuli will be displayed on a computer screen and the system will capture that “aha” moment if the information is present in the brain by using a series of proprietary algorithms. The perpetrator’s brain releases a tiny positive potential for every significant information involved in the crime and if this potential is captured and analyzed, then the result clearly shows that particular specific information is stored in perpetrator’s brain. iCognative will determine with 99.9% accuracy if the information is present or absent.
With this security innovative tool, the cold case of Leone Davis can be put to rest and her criminal put behind bars. iCognative aims to deliver justice at a global scale, aiding law enforcement in keeping their nations safe and protected.
