Search Warrant Update 600 North Farr Road


SWAT Team/SVIU Detectives Serve Search Warrant Gary B. Olive and Several Others Arrested

A search warrant was obtained by Spokane Valley Investigative Unit (SVIU) Detectives for the residence of 50-year-old Gary B. Olive Jr., an eight-time convicted felon who is well known to Deputies and Detectives for his decades of law enforcement contacts/arrests due to his continued criminal activity. Olive and four other suspects were detained early this morning by the Sheriff’s Office SWAT Team, who assisted in the execution of the search warrant.

Early in February 2018, SVIU Detective Jeff Thurman received information regarding Olive and his continued criminal activity. A SVIU investigation into Olive’s activities, to include the sales and use of controlled substances (Methamphetamine/Heroin/Others) and the possession/trafficking of stolen property (Motorcycles/Mini bikes) from his residence, located in the 600 block of N. Farr Rd., was initiated.

As the investigation progressed, Detectives identified several additional suspects and developed probable cause to arrest Olive for delivery of a controlled substance and obtained a search warrant for the location.

Early this morning, SVIU Detectives, the Sheriff’s Office SWAT Team, accompanied by Spokane Valley Fire Rescue Task Force members and Spokane Valley Patrol Deputies, staged in the area of the residence.

At approximately 7:30 a.m., with Air 1 providing additional security and information from above, the SWAT Team moved to the residence and served the search warrant. A short time later, Olive and four additional subjects were safely detained. Once cleared by SWAT, the scene was turned over to investigators to continue the search and collection of evidence.

Several items of property, believed to be stolen, were recovered by investigators. As they move forward with this investigation, Detectives will work to identify the owners of the property and identify any additional crimes committed by these and other suspects.

A black 1988 Chevrolet Corvette Convertible and a 2001 Honda CBR 900 motorcycle were seized by investigators who will begin the asset forfeiture process.

SVIU Detectives arrested the following six suspects in connection with this investigation for the listed charges. This is still an active investigation and additional charges and/or arrests are anticipated.

Gary B. Olive Jr. (50-year-old/male): three counts of Possession of a Controlled Substance with Intent to Deliver and three counts of Unlawful Use of a Building for Drug Purposes

John P. Oak (50-year-old/male): one count of Possession of a Controlled Substance and a felony warrant-Washington State Department of Correction Hold

Kamiel K. Gallagher (25-year-old/female): one count of Possession of a Controlled Substance

Ashley A. Mahome (27-year-old/female): one count of Possession of a Controlled Substance

Zenadiah M. Oswalt (21-year-old/female): two counts Possession of a Controlled Substance

Michael R. Sisneros (33-year-old/male): At approximately 7:00 a.m., Sisneros was observed leaving the area of the search warrant in a Nissan Altima. Being familiar with Sisneros from past calls for service and warrants for his arrests, Deputy Jason Karnitz checked Sisneros’ driving status and learned his driver’s license was suspended and stopped the vehicle on I-90 near the Hwy. 195 interchange. Sisneros’ identity was confirmed and he was arrested for driving with a suspended driver’s license.

During a search incident to the arrest, Deputy Karnitz located a baggie containing a white crystalline substance in Sisneros’ left front pants pocket. The substance was later field tested which showed a presumptive positive result for Methamphetamine.

Sisneros was transported and booked into the Spokane County Jail for one count of Possession of a Controlled Substance and Driving with a Suspended License.
