Pottawatomie County deputies say a disturbance call near Highland Road turned into a major gun bust last Friday, when they uncovered a stash of rifles, pistols, sawed‑off shotguns, high‑capacity magazines and a large quantity of ammunition hidden throughout a home. Two people were taken into custody after the incident; the sheriff’s office identified one arrestee as Michael Grossman, a convicted felon. Deputies also reported recovering suspected narcotics and drug paraphernalia and credited Deputy Mason Rempe for the work that led to the seizure.
According to a May 22 Facebook post by the Pottawatomie County Sheriff's Office, deputies had responded last Friday to a disturbance call at the Highland Road residence when they found the weapons concealed in several locations inside the home. The post says both suspects, Grossman and Tosha Walker, were transported to the Pottawatomie County Public Safety Center without incident. The office added the reminder that, "All suspects are presumed innocent until proven guilty."
What deputies say they found
The Pottawatomie County Sheriff's Office post lists what it described as "multiple rifles, pistols, sawed‑off shotguns, high‑capacity magazines and a large quantity of ammunition" hidden in several locations inside the residence, and says deputies also located suspected narcotics and drug paraphernalia. The post specifically credited Deputy Mason Rempe for his "thorough investigation and attention to detail," which the office said led detectives to the hidden cache. Because Grossman is a convicted felon, the sheriff's office noted that possession of the seized weapons would be unlawful under state and federal law.
Charges and the law
The sheriff's Facebook post did not list formal charges and said the inquiry is ongoing. Under federal law it is unlawful for a person convicted of a felony to possess firearms or ammunition (18 U.S.C. § 922(g)), as outlined by LII / Cornell Law School. Oklahoma statutes also restrict firearm possession by convicted felons; see Oklahoma Statutes, Title 21 on Justia for the relevant provisions.
Local enforcement context
The recovery is the latest update from a busy stretch for the sheriff's office. KOCO reported an April 30 investigation that led to arrests and the seizure of suspected fentanyl in Pottawatomie County, and tracked several of the office's recent public posts. The pattern of drug and weapons calls has prompted the department to routinely publish operational updates on its social channels.
What's next
The sheriff's office said evidence is being processed and the investigation remains active, and it did not list charges in the post. People with information can contact the Pottawatomie County Public Safety Center, which the county lists online at pcpsct.org.
