The lifeless corpse of
slotxo Ronald French, a bearded auto mechanic with twinkling eyes, is mysteriously found in a field in Kalamazoo County, Michigan.The Frenchman, an eight-year-old who has always been trying to help people, his daughter Ronda Hamilton told NBC affiliate WOOD of Kalamazoo disappeared three weeks ago. According to the police, the wires were wrapped around his neck, face and feet. He was dragged behind the car so vigorously that he had scratches on his back and partially flattened his skull. The medical examiner identified the death of the French as But then his grieving family did not hear anything about the arrest.For more than two years, the Kalamazoo County Sheriff's detective investigated the French murder without making any arrests.Then, according to police records obtained, one of the detectives learned about the branch that There is an emerging digital vehicle forensics that focuses on retrieving a treasure trove of data stored on a vehicle's onboard computer.
They go back to the 2016 black French Chevy Silverado pickup which was stolen around the time of his disappearance and discovered a timestamped recording of someone else's voice using a hands-free system to play Eminem on the radio during. The time when France was murdered The voice, according to a police report obtained by NBC News, was owned by Joshua Wessel, now 32, who was a homeless man in cars and motorcycles in French. Investigators were able to rebuild his movement and the last hours of the Frenchman's life, the police report said. In July, Wessel was arrested and charged with the murder of a Frenchman. He pleaded not guilty and was awaiting trial based on a psychiatric assessment.
Digital frontierIn recent years, investigators have found that cars, especially newer models, could be a treasure trove of digital evidence. Their onboard computers generate and store data that can be used to reconstruct where the vehicle is and what passengers are doing. They reveal everything from location, speed and acceleration to when doors open and close, from texting and calling while cellphones are plugged into an infotainment system, as well as voice commands and web history.But the boon for forensic investigators has raised fears for privacy activists, who warn that the lack of data security on vehicles' computers poses a risk to consumers and claimants. To be protected I have heard a lot of comparisons that cars are smartphones on wheels. But that has changed a lot, ”said Privacy4Cars founder Andrea Amico, which creates free apps that help people remove data from cars and make money from offering services, rental companies and dealerships. "If you think about the amount of sensors in your car, a smartphone is a toy. A car has GPS, an accelerometer, a camera. The car knows how much you weigh. Most people don't know this happens.
Treasure chestLaw enforcement agencies focus their investigative efforts to two main sources: the "black box" telematics system and the infotainment system. Telematic systems store turn-by-turn navigation, speed, acceleration and deceleration data, as well as more detailed information such as when and where the door lights were opened, seat belts and airbags. Was put into use The infotainment system records the latest destination information, call logs, contacts, messages, emails, photos, videos, web history, voice commands and social media feeds. It can also track phones connected to the car via USB cable or Bluetooth, as well as all apps installed on the device.Together, the data allows auditors to recreate vehicle trips and visualize the behavior of drivers and passengers. In criminal cases, the sequence of door opening and seat belt insertion helps to show that the suspect has an accomplice.
I'm sure everyone is aware of the forensic information on the phone," said Lam Nguyen, director of the Defense Cyber Crime Center, a federal forensic laboratory and training center. "What people don't know is that a lot of things get sent to the car just because you registered your phone with the car.But compared to smartphone security, system security is much more fragile, say experts in digital forensics and privacy. In general, drivers don't need to unlock their car's infotainment system with a password or fingerprint, like they do with a smartphone. That means law enforcement officers are sometimes easier to separate alleged messages, calls or files from a car than it can from a suspect's cell phone.
