A 911 hang-up investigation by the Graves County Sheriff's Office led to the arrest of four people on drug charges.
Sheriff Dewayne Redmon said an emergency call came into dispatch shortly before 3 a.m. Thursday from a woman stating she could not explain what was going on at an address on Burnett's Chapel Road, but firearms were involved.
When deputies arrived at the address just south of Farmington, they entered the house and reported contacting six people inside.
A search warrant was obtained. Items used in the manufacturing of methamphetamine were allegedly located along with a marijuana growing operation set up in a closet in a bedroom.
Deputies also located methamphetamine, marijuana and several items of paraphernalia. A backpack was found in one of the bedrooms that contained a handgun with the serial number removed.
Christopher Emerson, 46, the homeowner, was charged with manufacturing meth, cultivating marijuana less than five plants, first-degree possession of a controlled substance and possession of marijuana.
Justin Harrison 34, of Mayfield was charged with possession of a handgun by a convicted felon, possession of a defaced firearm, first-degree possession of a controlled substance and possession of marijuana.
Sabrina Weeks, 28, of Wingo and Cody Elkins, 31, of Hardin were charged with first-degree possession of a controlled substance and possession of marijuana.
The sheriff's office was assisted by the Mayfield Police Department.
