YCSO Traffic Stop Nets Nearly 5 pounds Of Meth

On July 28, 2016, just after 11:30 pm, a YCSO deputy stopped a blue VW passenger car for speeding on north I-17 at Bloody Basin Road, Yavapai County, Arizona. The vehicle contained 2 occupants – the driver identified as 29-year-old Jason Rosenbrook and his passenger, 21-year-old Taylor Sonderquist. Both are from Colorado. At the onset of contact, the deputy could detect an odor of marijuana coming from the inside the vehicle. Rosenbrook told the deputy he knew ‘Taylor’ for about 3 months, but could not provide her last name and neither party could clearly answer basic questions that two persons sharing a destination would commonly know. These issues, along with the observed marijuana odor, raised the deputy’s suspicions that drugs would be found inside.

During a check of the vehicle interior to find the source of the odor, the deputy located a usable amount of marijuana, drug paraphernalia including multiple syringes, and a loaded semi-automatic firearm. A case containing a large amount of packaged methamphetamine was found in Sonderquist’s purse. In the trunk, the deputy found additional cases containing methamphetamine in multiple bags and a backpack concealing large blocks of methamphetamine wrapped in plastic.

It was later determined the total weight of methamphetamine seized at 4.75 pounds. Sonderquist admitted she is an intravenous meth user and admitted to possessing the meth found in her purse. Rosenbrook told deputies the majority of the remaining meth belonged to him. Deputies also found counterfeit currency which was connected to both suspects.

As a result, the suspects were booked at the Camp Verde Detention Center on charges including Possession of a Dangerous Drug/Narcotic, Transport Dangerous Drug/Narcotic for Sales, Possession of Firearm during Commission of a Felony, and Forgery. Rosebrook’s bond is set at $25,000 and Sonderquist has a bond of $75,000. They remain in-custody.

Detectives from the Partner’s Against Narcotics Trafficking (PANT) task force arrived and are now handling the investigation. As part of the follow-up, they are looking into the use of personal checking accounts to transfer money utilized in drug transactions. Bank account holders participating in such a scheme will be sought out and prosecuted as part of the overall case.
