Lethbridge weapons seizure nets two dozen firearms, nearly 200 knives and drugs after July 15 raid
ALERT and Lethbridge police seized two dozen firearms, about 170 knives, drugs and cash during a July 15, 2026 search of a northside residence, leading to two arrests.
Major seizure executed in Lethbridge on July 15, 2026
A coordinated search warrant executed on July 15, 2026, by the Alberta Law Enforcement Response Team’s (ALERT) Lethbridge organized crime unit, with assistance from Lethbridge police, resulted in what ALERT described as one of the agency’s largest weapons seizures. The operation targeted a residence in the 2000 block of 7 Avenue North after an investigation into suspected drug trafficking. The Lethbridge weapons seizure is now the focus of an expanded probe involving provincial and federal investigators.
ALERT said the search uncovered a mix of firearms, prohibited weapons and a large number of edged weapons, along with drugs and cash. Investigators arrested two individuals at the scene and have since laid a series of charges connected to trafficking, firearms offences and possession of proceeds of crime.
Detailed inventory of weapons and tactical gear
ALERT reported that investigators seized two dozen firearms, specifying an inventory that included 19 rifles, three shotguns and one pistol, in addition to nine replica firearms and 12 items classified as prohibited weapons. The haul also contained approximately 4,700 rounds of ammunition. Two body armour vests were recovered, underscoring the paramilitary nature of some of the cache.
Officers also recovered about 170 knives and edged weapons, described by ALERT as including switchblades, swords, nunchakus, collapsible batons, brass knuckles and novelty items such as “Freddy Krueger-type claws.” Police said the volume and variety of edged weapons were notable and raised immediate safety concerns for investigators and the public.
Drugs, cash and contraband found alongside arms
The search turned up a range of controlled substances and contraband tobacco estimated at roughly $20,000 in total street value, according to ALERT. Seized drugs included 53 grams of cocaine, 41 grams of methamphetamine, 538 fentanyl and oxycodone pills, and 113 LSD tabs, alongside 20 cartons of contraband tobacco products. Cash totalling $13,649 was also seized under proceeds‑of‑crime provisions.
ALERT officials said the combination of narcotics and weapons suggested organised drug trafficking activity rather than isolated possession. The agency indicated the items appeared to be linked to an active local trade that may involve exchanges of weapons for drugs.
Charges and identities of those arrested
Two people were arrested at the residence when the warrant was executed and have been charged in relation to the seizure. Police identified the accused as 47‑year‑old Louise Sansome and 56‑year‑old Terry Adamson. Sansome faces multiple charges including possession of drugs for the purpose of trafficking, possession of proceeds of crime, possession of body armour, offences under the Tobacco Act and a series of firearms‑related charges.
ALERT noted that Sansome is subject to a lifetime firearms prohibition stemming from prior convictions, a factor that will figure prominently in the prosecution’s case. Adamson has been charged with possession of drugs. Court dates and further procedural details were not released as police continue the investigation.
Investigators tracing origins of the arms cache
ALERT said none of the firearms were lawfully possessed and that investigators are working with the RCMP to determine where the weapons came from and whether they connect to wider trafficking networks. So far, police have linked at least one firearm to a theft reported in Brooks, Alberta, about 150 kilometres southeast of Calgary. That trace is part of a broader effort to map out distribution channels and identify possible thefts, straw purchases or cross‑jurisdictional transfers.
The RCMP’s involvement reflects the multi‑agency nature of the probe and the potential for the weapons to have been sourced or moved across municipal and provincial lines. ALERT did not disclose whether the investigation has identified additional suspects or linked the seizure to specific organized crime groups.
Public safety and policing implications in Lethbridge
ALERT described the operation as a significant disruption to suspected drug trafficking activity in Lethbridge and emphasized the public safety risk posed by the volume of firearms and edged weapons recovered. The presence of body armour, high ammunition counts and prohibited items heightened concerns about potential violence if those items had been circulated in the community. Local policing officials said the seizure demonstrates ongoing efforts to remove dangerous material from circulation.
Community members and local stakeholders were not quoted directly by police, but the scale of the haul is likely to prompt renewed calls for targeted enforcement and partnership approaches to disrupt the supply chains that feed street‑level trafficking. Police indicated that ALERT and Lethbridge officers will maintain investigation momentum and pursue any leads that emerge from forensic analyses and intelligence work.
The investigation remains active, with investigators continuing to catalogue evidence, conduct ballistics and forensic testing and coordinate with the RCMP on traces and intelligence sharing following the July 15, 2026 search. Further charges and disclosures are possible as the probe develops and as Crown counsel reviews the evidence gathered at the scene.
