The Somerset Police Department says officers have made an arrest in a Pulaski County murder case. Investigators say 34 year old Bradley Allen McMahan was taken into custody on East Mount Vernon Street. He is accused of traveling from Maryville, Tennessee to murder 59-year-old Johnnie Faye Davis. McMahan was the ex-boyfriend of Davis’ daughter, who has issued an emergency protective order against him. Neighbors say Davis was concerned about her daughter’s relationship. Davis had recently taken custody of her daughter’s children. McMahan was taken to the Pulaski County Detention Center. He faces a murder charge for now, but more charges may be added. Police are investigating to see if anyone else was involved in the murder.
