A crew from Colombia used high-tech gear to break into homes across Southern California.
Four men were caught after a string of residential break-ins that relied on signal jammers and fake plates to bypass home security.
It is a nightmare to think that your home security system might be working against you. Four men are now in custody after police say they used advanced tech to slip past alarms and cameras.
What Happened
The San Bernardino County Sheriff’s Department arrested four Colombian nationals following a burglary in Upland on April 22. The men were identified as Akssel Cadena-Diaz, Jesus Velez-Hernandez, Sergio Paez-Cuervo, and Javier Pulido-Ramirez.
Investigators say the group did not just kick in doors. They used signal jammers to kill WiFi and security feeds, along with hidden cameras to watch homes before they struck. They also used fake license plates to hide their tracks while moving between neighborhoods.
Detectives tracked the group to locations in Los Angeles County. During raids, police found stolen goods, specialized tools, and the electronic gear used to disable home alarms.
What the money/evidence shows
- Four suspects arrested: Akssel Cadena-Diaz, Jesus Velez-Hernandez, Sergio Paez-Cuervo, and Javier Pulido-Ramirez.
- Investigation began after a burglary in San Antonio Heights on April 22.
- Tools recovered include WiFi and signal jamming devices.
- Police found camouflaged wireless cameras used to monitor homes.
- Fake license plates were used to avoid detection during the crimes.
The Bigger Question
We have to ask how these crews are getting the gear to beat modern home security. If a standard alarm system can be jammed by a device bought online, are our homes actually safe?
This case shows that criminals are keeping pace with tech. It forces us to wonder if the security industry is doing enough to protect homeowners from these specific types of digital bypasses.
The Other Side
The suspects are currently in custody and have not yet had their day in court to respond to these claims. Based on the evidence of the tools found during the raids, the case against them appears to be quite detailed.
What Happens Now
Three of the men are being held in Ventura County, while the fourth is at the West Valley Detention Center. Police are now using this case to warn the public about how these crews operate.
If you live in the area, check your security settings and make sure your cameras are not easily jammed. Local police are asking anyone with more info to call the Fontana Sheriff’s Station at 909-356-6767.
What We Still Don't Know
- How many homes were targeted in total by this specific crew?
- Where did the group get the specialized jamming equipment?
- Are there other members of this crew still at large in the region?
