EUGENE, Ore. — Four Colombian nationals who were unlawfully residing in the United States have been sentenced to federal prison for their roles in a sophisticated multi-state burglary conspiracy that targeted Asian American small business owners in Oregon and Washington, federal prosecutors announced.
Following their federal sentencing hearings Tuesday, each defendant also received additional prison sentences in state court for the burglaries.
The defendants were sentenced as follows:
- Derinson Martinez-Grandas, 34: 12 months and one day in federal prison, followed by 10 months in state prison.
- Jhon Alexander Quintero, 45: 18 months in federal prison, followed by 15 months in state prison.
- Steven Alexander Quiroga-Solano, 28: 21 months in federal prison, followed by 18 months in state prison.
- William Estiven Rodriguez-Gaviria, 27: 12 months and one day in federal prison, followed by 10 months in state prison.
Each defendant was also ordered to serve three years of supervised release after completing their prison terms and must forfeit stolen property proceeds and equipment used to carry out the crimes.
According to court documents, the burglary crew traveled from California through Nevada and Idaho before operating in Washington and Oregon. Investigators said the group specifically targeted Asian American business owners by researching potential victims and their businesses online before conducting surveillance of both the businesses and the owners’ homes.
Authorities said the defendants rented short-term vacation properties to use as operational bases while carrying out the burglaries.
The crew employed sophisticated tactics to avoid detection, including commercial-grade Wi-Fi signal jammers, perimeter countersurveillance, and seven-way group phone calls to coordinate their activities. They typically forced entry by shattering glass doors before ransacking homes and stealing U.S. and foreign currency, jewelry, luxury handbags, wallets, travel documents and other valuables.
After each burglary, investigators said the suspects returned to their rental homes to package the stolen property for transport or shipment to California and Colombia.
The investigation intensified following a burglary in Salem, when detectives tracked the suspects to a rental property in Eugene. A search warrant executed that night led investigators to recover cash and property believed to have been stolen from multiple homes, more than a dozen cell phones allegedly used by the burglary crew, evidence of money transfers to Bogotá, Colombia, and Colombian travel documents, including passports.
Investigators also discovered commercial-grade Wi-Fi signal jammers plugged in and charging after what authorities believe was their use during the Salem burglary.
A forensic examination of the defendants’ electronic devices uncovered additional evidence linking them to the conspiracy. Prosecutors said investigators found GPS coordinates for targeted homes, surveillance communications, and messages discussing burglary targets.
According to prosecutors:
- Martinez-Grandas rented properties for the group in Auburn, Washington, and Eugene, and mapped the Salem residence on the day it was burglarized.
- Quintero researched jewelry values after a burglary in Auburn and contacted a Colombian shipping company two days after the Eugene burglary.
- Quiroga-Solano searched for Chinese restaurants before the crew burglarized the home of a family that owned one and was observed near a Gresham victim’s home the night before it was burglarized.
- Rodriguez-Gaviria sent a co-conspirator the address of a burglary victim on the day of the crime and allegedly posed as a food delivery driver at two targeted homes before the burglaries occurred.
A federal grand jury in Eugene indicted the four men on Nov. 20, 2025, charging them with conspiracy to commit interstate transportation of stolen goods. Between March and May 2026, all four defendants pleaded guilty to the conspiracy charge.
U.S. Attorney Scott E. Bradford for the District of Oregon announced the sentences.
The case was investigated by the Federal Bureau of Investigation and the Eugene Police Department, with assistance from the Salem, Auburn and Gresham police departments. Assistant U.S. Attorney William M. McLaren prosecuted the case.
