Police seized more than 18 pounds of crystal meth and arrested two brothers in an undercover drug bust in Nashville.
Roberto and Jose Flores-Sanchez were arrested and charged with unlawful gun possession, meth possession with intent to sell, and marijuana possession.
The two-week investigation ended when the men were parked in the Dickerson Pike Walmart parking lot to make a suspected drug deal.
Detectives searched the car and found the meth, 17 grams of marijuana, one loaded handgun, and $1,680 in cash.
The men were being held in lieu of $92,000 cash bond.
