A narcotics investigation in Jacksonville’s Moncrief neighborhood ended with a search warrant at a house near West 21st Street and Moncrief Road and what police described as a large cache of drugs, weapons and cash.
Detectives with the Jacksonville Sheriff’s Office say officers seized more than 20 pounds of marijuana, about 17 grams of fentanyl, which the department described as more than 8,600 potentially deadly doses, along with methamphetamine, synthetic cathinones, heroin, two firearms and several hundred dollars in cash. A 42-year-old man was arrested at the scene and taken into custody. Detectives said the probe grew out of suspected drug activity they observed at the property.
In a social media post, the Jax Sheriff’s Office said narcotics-unit detectives and a SWAT team served a search warrant on March 3 and removed 17.2 grams of fentanyl, 20.8 pounds of marijuana, 33.4 grams of methamphetamine, 81.8 grams of cathinone, 2.3 grams of heroin, a handgun, a rifle and more than $500 in cash. The post named the arrestee as Carlos Cooper, 42, and noted he is a convicted felon with multiple prior drug charges.
Fentanyl remains central to drug threats in Florida
Fentanyl continues to be the leading drug identified in overdose deaths across Florida even as total drug fatalities fell in recent reporting. According to the Florida Department of Law Enforcement, fentanyl was the top substance noted in the state’s 2024 Medical Examiners report. Local reporting has credited focused enforcement and prevention work with driving down overdose deaths in Jacksonville while law enforcement continues to intercept high volumes of opioids; Jax Today detailed those trends and recent seizures.
How the probe unfolded and how to report tips
The sheriff’s office says detectives opened the investigation after noticing suspected drug activity at the Moncrief property and obtained a search warrant before the March 3 operation. In its post, the Jax Sheriff’s Office asked residents to report drug houses or suspicious behavior to 904.630.0500 and included photos and an inventory of the items seized. The agency said detectives from the narcotics unit handled the case with SWAT support.
Potential charges and legal notes
Because the seizure involved controlled substances and firearms, prosecutors could pursue drug-trafficking and weapons charges if formal counts are filed. Possession and trafficking of controlled substances are covered under Chapter 893 of the Florida Statutes, and convicted felons are barred from possessing firearms under section 790.23, according to the Florida Senate and the Florida Senate.
Court records and booking logs will show what charges, if any, are filed and when the arrestee will appear. The sheriff’s office said it will continue the investigation and urged anyone with information to call 904.630.0500.
