WILLIAMS, IOWA – This apparent drug dealer tooling around the Northern Iowa countryside in a motorhome loaded with poisonous substances, scales, baggies and more was sniffed out by a nosy law enforcement officer and is now stationary in a jail cell.
On October 24, 2025, at approximately 4:50 PM, a Hamilton County Deputy was patrolling the Flying J parking lot at 3040 220th Street in Williams, Iowa, when he ran a license plate that did not come back to the vehicle it was attached to. He made contact with the vehicle, a 1986 Ford Coachman, and met with the admitted owner Robbie Lyn Walker, age 49 of Williams, Iowa, who says she didn’t know about the license plate. The Hamilton County Dispatch Center was able to locate a phone number for the rightful owner of the license plate who says Walker should not be in possession of that license plate.
When that was known, the deputy contacted Walker again but this time the Hamilton County K9 unit was involved for assistance. Walker agreed to stay inside the motorhome while an outside narcotic sniff from the K9 was conducted. The K9 positively alerted to the odor of narcotics from the vehicle.
At that time, a probable cause search was conducted. Walker handed over a marijuana smoking pipe before leaving the motorhome. During the probable cause search, numerous items dealing with illegal narcotics and the distribution of narcotics were located which included but are not limited to; Psilocybin mushrooms, marijuana, methamphetamine, digital scale, multiple small baggies commonly used to package narcotics, storage containers with residue from narcotics, drug paraphernalia, and grinders.
A search warrant was later applied for and granted access to the cell phones that were also located.
With the permission of the signed search warrant, it was found that it appears multiple people were buying/selling these narcotics from Robbie Walker, that Walker had earlier admitted to selling.
On October 26, 2025, when the Hamilton County Sheriff’s Office was in route to apprehend Walker, they located her driving away from the Flying J with the motorhome. A traffic stop was conducted as it was known that Walker does not have a license.
Robbie Lyn Walker was arrested and transported to the Hamilton County Jail where she has a $48,200 criminal bond. She is charged with the following:
• Ongoing Criminal Conduct (706A.2(4) Class B Felony
