LOUISVILLE, Ky. (WDRB) -- An alleged drug-money courier has been arrested at a south Louisville apartment complex. 

WDRB cameras were there as the Bullitt County Drug Task Force arrested Ronnie Shewmaker at an apartment complex off Saint Andrews Church Road. 

Investigators aren't saying what Shewmaker is charged with, but on Wednesday, our newsroom uncovered documents which say Shewmaker was a drug money courier. Law enforcement believes Shewmaker was working for Chris Mattingly, who is a former Bullitt County Special Deputy already behind bars. Mattingly was indicted in September for conspiracy to distribute more than a ton of marijuana. 

Shewmaker was taken to the Grayson County Jail, which is used to hold some federal inmates. Investigators learned about Mattingly and Shewmaker through wiretaps. WDRB traveled to Perris, California where Shewmaker was arrested in May of 2014 with about $420,000 in cash.  He's been under investigation for years.  During his arrest, Shewmaker cooperated with law enforcement.  

Mattingly's attorneys are trying to get him released from jail and want the wiretap evidence thrown out. Mattingly is accused of operating as the head of a drug cell in Kentucky with ties to a Mexican Cartel. 

Documents show the money from the sale of narcotics in Kentucky are eventually transported back into Riverside County, California, which is considered the drug hub of the U.S.
