Washington County detectives have arrested three suspects who they believe are responsible for committing more than 40 burglaries across the Portland metropolitan area since April 2011.
A fourth suspect is on the run and believed to be in Vancouver, Canada.
The suspects are from Texas, and detectives believe they would drive to Portland in rented vehicles, commit the burglaries and then drive quickly back to Texas.
They bought tools from local hardware stores to use in the crimes and then threw them away before heading back to Texas, according to deputies.
The thieves targeted victims who they believed would have gold or jewelry in their homes.
Deputies say the suspects would then break in to homes when they thought the residents were away. Investigators say they would often smash in a rear door to gain entry to the homes.
On two occasions, suspects discovered residents unexpectedly at home. They bound the victims with items found in the house during the robbery. Fortunately, no one was hurt.
Ana Maria Gutierrez, 32, is lodged in the Washington County Jail, charged with theft, burglary, robbery and kidnapping.
Rodney Portocarrero Riascos, 18, is lodged in a Houston jail awaiting extradition.
Deenys Yossimar Ramos, 24, is lodged in a Houston jail awaiting extradition.
Vanderly Ortiz, 30, is believed to be in Canada, avoiding current warrants for his arrests.
Detectives believe the four may be connected to similar crimes in Colorado, Virginia, Georgia and Washington. They have no known ties to Oregon.
Deputies say the suspects stole close to $1 million in valuables when all is said in done.
Detectives continue to seek information in these cases. If you have any information, call the Washington County Sheriff's Office at 503-846-2500.
