Ventura County, California – Three members of a sophisticated burglary crew responsible for a multi-million dollar jewelry heist in Simi Valley have been sentenced to prison, prosecutors confirmed last week. The group drilled through a shared wall between two neighboring businesses and stole more than $2 million in cash and merchandise.
The case, described by authorities as highly organized and professionally executed, drew attention across Southern California due to the scale of the theft and the elaborate planning involved.
Incident Overview
The burglary occurred on May 25, 2025, at 5-Star Jewelry & Watch Repair and Dr. Conkey’s Candy and Coffee Shop, located in a strip mall in the 2800 block of Cochran Street in Simi Valley.
According to the Ventura County District Attorney’s Office, the crew entered the businesses by climbing onto the roof using a ladder. They cut through the roof above a bathroom area behind the candy shop, then drilled through a shared interior wall to access the jewelry store next door.
Once inside, they broke into safes and made off with more than $2 million in jewelry, watches, cash, and silver merchandise.
Timeline of Events
Prosecutors detailed a calculated sequence of planning that began days before the heist.
On May 16, two suspects drove to a Home Depot store where a rope was allegedly stolen for use in the crime. On May 20, three suspects traveled in a white Volvo SUV to the targeted shopping center and conducted surveillance.
Authorities said the suspects observed the interior of the jewelry store through its front window before entering the candy shop to assess surveillance cameras and inspect the shared wall.
The District Attorney’s release stated:
“One suspect used a cell phone flashlight to examine the walls, another acted as a lookout, and a third allegedly mimicked the use of a spray can, indicating plans to disable security measures.”
Five days later, on May 25, the crew returned to carry out the burglary. They spray-painted a security camera inside the candy shop, stole cash from its safe, and then breached the wall into the jewelry store.
Statements From Officials
Ventura County District Attorney Erik Nasarenko described the group as experienced professionals with international ties.
“These were not teenagers burglarizing a local business to score quick cash,” Nasarenko said when the suspects were arrested. “Rather, they were sophisticated and skilled professionals who used counter-surveillance measures, a collapsible ladder, rope, and power tools to cut through a roof, tunnel through a wall, breach a safe – to take millions in watches, jewelry, cash and other merchandise.”
Authorities identified the suspects as Chilean nationals with alleged connections to a South American theft group.
Store owner Jonathan Youssef, who operates the jewelry business with his father Jacob Youssef, previously said:
“These guys were professional thieves. They had a plan; they must’ve cased us.”
Arrest and Recovery of Stolen Items
All four suspects were arrested approximately two weeks after the burglary when detectives served a search warrant at a home in Canoga Park, Los Angeles County.
Investigators recovered a significant amount of the stolen property. According to Nasarenko, some suspects were wearing stolen jewelry at the time of arrest, while others were carrying stolen items in bags.
Prosecutors also revealed that cell phone videos recovered during the investigation showed suspects actively breaking into a safe, sorting stolen gold, and handling jewelry.
Sentencing Details
In January, all four defendants changed their pleas to guilty after initially pleading not guilty.
The following sentences were announced:
- Manuel David Ibarra, 38 – Four years and four months in Ventura County Jail
- Camilo Antonio Aguilar Lara, 27 – Four years and four months in Ventura County Jail
- Heidy Nickolt Trujillo, 26 – Four years in jail
- Sergio Andres Mejia-Machuca, 32 – Sentencing continued to March 26
Ibarra, Lara, and Mejia-Machuca pleaded guilty to felony conspiracy to commit commercial burglary and possession of stolen property. Ibarra and Mejia-Machuca also admitted to conspiracy and felony vandalism related to a separate burglary at Sim Valley Pawn Brokers just two days before the jewelry heist.
Trujillo pleaded guilty to a single felony count of conspiracy to possess stolen property.
Each defendant admitted special allegations including excessive loss exceeding $1 million and committing theft in concert with others under Proposition 36. Prosecutors also cited aggravating factors, noting the planning, sophistication, and professionalism demonstrated during the crimes.
Public Safety and Crime Prevention Context
Large-scale commercial burglaries like this often involve organized crews targeting high-value retail businesses. Authorities say such groups frequently conduct advance surveillance, use specialized tools, and transport stolen goods quickly across county lines to avoid detection.
Business owners are encouraged to regularly evaluate security systems, reinforce roof access points, and ensure surveillance cameras are positioned to prevent tampering.
Law enforcement agencies continue to monitor organized retail theft operations across California, particularly those involving interstate or international networks.
Conclusion
The sentencing of three members of the Ventura County burglary crew marks a significant development in a case that shocked local business owners. Prosecutors emphasized that coordinated law enforcement efforts led to swift arrests and the recovery of stolen property.
As sentencing for the fourth defendant approaches, authorities say the case serves as a reminder that organized commercial theft carries serious legal consequences.
