Investigations and Search Warrant Result in Recovered Property and Two Arrests for Multiple Burglaries in Yamhill County (Photo) - 08/06/20

On May 14, 2020 about 6:00 am Deputy Jacob Rex took a report of an extensive burglary of a commercial building located in the 100 block of W. Main Street in the city of Yamhill.  The building was entered, and a substantial amount of property was stolen including multiple chainsaws, firearms, and a fully restored 1958 Chevrolet Pickup.  The value of the stolen property exceeded $50,000.  The Sheriff’s Office requested assistance from the public in locating the stolen pickup and property which resulted in a number of tips and reports of possible sightings of the truck from as far away as Southern California.  Video evidence from a neighboring business provided some investigative leads.


Also, on May 14, 2020 Deputy Jaime Cerda took a report of a burglary of an industrial storage container belonging to Portland & Western Railroad located near Oregon Vineyard Supply on St. Joseph Rd in rural McMinnville.  Specialty tools were taken, and again, video evidence from a neighboring business provided investigative leads.


On May 15, 2020 an alert county resident reported seeing a truck they believed to be the stolen 1958 Chevrolet pickup parked at the McBride Cemetery in rural Carlton.  Deputies Claire Cannetti and Rich Broyles responded and recovered the stolen pickup, returning it to the owner.  On May 26, 2020 Deputy Jacob Rex took another report of a theft of specialty tools belonging to McMinnville Water and Light.  The tools were taken from Mac Water and Light trucks at a power substation located along Hwy 18 in rural McMinnville.  The stolen tools were somewhat unique to utility work and not common tools.


Through investigation and information sharing between the responding patrol deputies and detectives with the Crime Response Team (CRT) Detective Jacob Herr authored and was granted a search warrant for a property located in the 17000 block of NE Geelan Rd in rural Yamhill.  During the execution of the search warrant on May 30, stolen property from the burglary in the city of Yamhill, the Portland & Western railroad storage facility, and Mac Water and Light trucks was recovered.  Additionally, user amounts of both methamphetamine and heroin were seized.


Two adult males were identified as the suspects in these cases.  On June 3, 2020 the first suspect, Riley Martin, age 27, of rural Yamhill was arrested and lodged in the Yamhill County Jail for multiple charges stemming from all these cases including:  Aggravated Theft 1st Degree, Theft 1st Degree, Burglary 2nd Degree, Criminal Trespass 2nd Degree, Criminal Mischief 3rd Degree, Unlawful Use of a Vehicle, Unlawful Possession of Methamphetamine, Unlawful Possession of Heroin, and Unlawful Entry into a Motor Vehicle.  The booking bail amount was $65,000. 


The second suspect was located and arrested on August 4, 2020.  He is identified as Brock Keinonen, age 32, of Carlton.  Mr. Keinonen was located and arrested at the McBride Cemetery on warrant stemming from a grand jury review of these cases resulting in an arrest warrant being issued.  He was lodged in the Yamhill County Jail on the warrant.


The Yamhill County Sheriff’s Office would like to thank the residents and businesses who assisted with these investigations by providing tips and video surveillance, and the Yamhill Police Department for their assistance.

Former Treasurer of Newberg Animal Shelter Arrested on Embezzlement Charges (Photo) - 07/22/20

On July 21, 2020 Yamhill County Sheriff’s Office arrested Laura Marie Stone, 39, of Newberg after an extensive, six-month investigation into an ongoing theft scheme perpetrated by Stone while she was associated with the non-profit Newberg Animal Shelter in Newberg, OR. 

The investigation alleges Stone, who was on the Newberg Animal Shelter Board and served as Treasurer from January of 2017 through December of 2019, disabled the shelter’s PayPal account and arranged for over $16,000 of donated funds to be directly transferred to her personal PayPal account.  Additional financial investigation revealed that Stone stole an additional $70,000 of cash donations and animal adoption fees from the shelter over that same time frame.

Special Investigations Unit Detective Will Lavish, the primary investigator in the case, obtained financial histories and information and developed the evidence needed for the arrest and presentation to the Grand Jury which resulted in a warrant being issued.  He worked closely with the Newberg Animal Shelter Board members who assisted openly with the investigation. 

Stone was arrested and lodged into the Yamhill County Correctional Facility on 8 counts of Theft in the First Degree and Misapplication of Entrusted Property.  Her bail was set at $75,000.

La Pine Resident Arrested in Extensive Fraud Case from Yamhill County (Photo) - 07/21/20

On February 24, 2020 Oregon Pride Nursery, which is located in rural McMinnville, filed a criminal report with the Yamhill County Sheriff’s Office involving suspected fraud.  The business located some suspicious transactions and performed an extensive audit of their books, finding suspicious transactions dating back to 2013.

Over the course of several months, Oregon Pride Nursery worked with an accounting firm and Yamhill County Sheriff’s Office Detective Jacob Herr, identifying that from 2013 until 2019 approximately $4.4 million dollars had been embezzled by a former employee, identified as 61 year-old Jeanna Lee Buxton, who currently resides in La Pine, OR. 

The case was presented to a Yamhill County Grand Jury who returned an indictment charging 21 counts of Aggravated Theft in the 1st Degree.  A warrant was issued for the arrest of Jeanna Lee Buxton with a bail amount of $200,000.

On July 20, members of the Yamhill County Sheriff’s Office Criminal Response Team (CRT) contacted Jeanna Lee Buxton at her residence and took her into custody on the outstanding warrant.  She was lodged into the Deschutes County Correctional Facility in Bend.

The Yamhill County Sheriff’s Office would like to thank Oregon Pride Nursery for their extensive cooperation in this complex investigation, and the Deschutes County Sheriff’s Office for their assistance in the arrest.

Newberg Swimmer Located Deceased In Willamette River (Photo) - 07/20/20

At approximately 6:00 p.m. this evening, callers phoned 911 to report an 18 year old male had disappeared while swimming in the Willamette River near Roger's Landing in Newberg. Callers advised the male was not wearing a personal flotation device.

TVF&R’s Water Rescue Team quickly responded from the Newberg fire station and began searching the water by boat, utilizing thermal-imaging technology and rescue swimmers. 

The search was eventually modified to a recovery mission with the assistance of the Lake Oswego Fire Department Dive Rescue Team. 

At around 8:45 p.m. the swimmer was located deceased, in about 20 feet of water, a short distance downstream from Roger’s Landing.  He was identified as Wesley J. Warmoth, 18, of Newberg. 

"Our hearts go out to the family of this young man.” said Sheriff Tim Svenson. “This is a tragic situation that unfortunately plays out all too often in Oregon rivers and lakes. We will keep this family in our thoughts.”

In addition to TVF&R’s Water Rescue Team and the Lake Oswego Fire Department Dive Rescue Team, assistance was provided by the Newberg Police Department and the Yamhill County Sheriff’s Office Marine Patrol.
