The Shelby County Drug Enforcement Task Force and the Helena Police Department made four arrests and seized drugs, guns and cash after executing a search warrant on Tuesday.Authorities said the drug bust occurred at a home in the 1400 block of Secretariat Drive in Helena, where investigators found nearly three pounds of marijuana, two pounds of mushrooms, two bottles of codeine, over 90 grams of THC wax, drug paraphernalia, multiple firearms, and more than $29,000 cash. Three residents of the home were arrested on various drug charges including trafficking marijuana, unlawful possession of a controlled substance, and unlawful possession of drug paraphernalia. An 18-year-old who was at the residence during the search was arrested on charges of possession of marijuana and drug paraphernalia. "The Shelby County Drug Enforcement Task Force realizes that without collaborative efforts between other agencies, these types of narcotics investigations would not be successful," the task force stated in a post on social media. "We would like to thank the Helena Police Department for their assistance in this operation and their ongoing support of our mission."
