JACKSONVILLE, Fla. —  A major drug operation in the Brentwood neighborhood has been dismantled following a joint investigation by Jacksonville Sheriff’s Office Narcotics detectives and District 5 Task Force officers. JSO says the amount of fentanyl they confiscated was “enough to kill more than 600,000 people,” which they noted is “half the entire population of Jacksonville.”

Last month, detectives received a tip about suspected drug activity at a home on West 27th Street, according to a release. Authorities say the residence was being used to distribute dangerous narcotics throughout the downtown area.

After weeks of surveillance and evidence gathering, officers executed a search warrant at the location last week—uncovering a staggering cache of illicit substances, weapons, and stolen property.

• 1,200+ grams of Fentanyl (Enough to kill more than 600,000 people, according to JSO) 
• 1,387.2 grams of Cathinone
• 492.5 grams of Crack Cocaine
• 165.1 grams of Powder Cocaine
• 115.2 grams of Ecstasy
• 7.1 grams of Heroin
• 6.2 pounds of Marijuana

In addition to the drugs, detectives found five firearms, including one with an illegal switch and another reported stolen.

Five suspects have been arrested and are facing felony charges: Yahya Ali, 48; Alshawn Martin, 47; Bilal Ali, 20; Tywanna Davenport, 40; and James Johnson, 54.

The drug house was located alarmingly close to a church, a library, and Andrew Jackson High School, according to JSO. Authorities say its takedown is a major step toward keeping the community safe.

“We’re making Jacksonville a safer place for you and your family,” the Sheriff’s Office said in a statement.

Residents who notice suspicious activity are encouraged to report it by calling 904-630-0500.
