LOUISVILLE, Ky. (WDRB) -- Louisville Metro Police say they've arrested three people in connection with the discovery of over 100 pounds of marijuana inside the home of one of the city's biggest suspected drug dealers.

According to arrest reports, police executed a search warrant at a home on Monaco Drive, near the intersection of Outer Loop and Shepherdsville Road Thursday night. Police say they were looking for narcotics.

Neighbors say it was scary and shocking as they watched police move in on the suspect.  

"A black SUV pulled up right here, jumped out real quick, opened up the back, throwing on the bulletproof vest and his weapon," Sandra Lynch said.

While searching the home, officers allegedly found over 100 pounds of marijuana, four handguns (one of which was stolen), one shotgun and $500,000 in cash. 

"There was a total of $500,000 cash, which when we added up collectively with investigations involving this individual, we're looking at a million dollars cash seizure," said Major Frank Hardison with LMPD's 3rd division. 

Police arrested 33-year-old Kristopher Reed, who lived at the home, according to an arrest report. He is charged with enhanced trafficking of marijuana, possession of a handgun by a convicted felon, trafficking in a controlled substance and enhanced receipt of stolen property.

Police say they had also stopped a black Volvo, driven by 31-year-old Prince Peterson, after it left the home on Monaco Drive. Officers initially stopped Peterson for failing to use a turn signal, but said they could detect the strong smell of marijuana coming from the car.

Peterson allegedly told them that he had a marijuana pipe inside. Police say they eventually found a large suitcase in the back seat, partially open, containing about 20 pounds of marijuana.

"Apparently, he had it in the attic because one of the police officers came out and said, it was up high," Lynch said.

Peterson was arrested and charged with failure to (or improper) signal, trafficking in marijuana and receipt of stolen property.

According to arrest reports, police had also arrested 33-year-old Joseph Lanham after he was seen driving a blue Honda away from the home on Monaco Drive. Lanham was also stopped for failing to use his turn signal. According to police, they could smell marijuana coming from his vehicle, and recovered about 10 pounds from inside.

Lanham was arrested and charged with trafficking in marijuana, trafficking in a controlled substance, receipt of stolen property and failure to (or improper) signal.

Hardison said it was all part of an extensive, long-term investigation, where Lanham was the target. 

"He is one of the busiest and largest traffickers inside Metro Louisville," Hardison said. 

All three of the men are being held in Louisville Metro Corrections. Police say this is an ongoing investigation and there could be more arrests made.
