Cocke County deputies who Thursday morning responded to a home at 440 Padgett Mill Road in the Cosby community found an armed woman and another woman who had died of a gunshot wound.

Cocke County Sheriff Armando Fontes identified the gunshot victim as Adena Parton, 58, a resident of the home.

Late Thursday, Martha F. Styles, 45, another resident of the home allegedly admitted to shooting Parton.

She has been charged with first degree murder and is being held in the Cocke County Jail on a $200,000 bond.

The sheriff says the motive in the shooting is unclear but suspected drug use may have been involved.

The incident began at 4:40 a.m. when 911 received a call from a female at the home saying an incident had occurred at the residence.

Deputies arriving on the scene heard several gunshots coming from within the residence.

Officers took cover and “at the rear of the residence they could see a female in a window holding a handgun. She was waving the weapon around beating on the window and officers ordered the female to drop the weapon,” the sheriff said. “Ms. Styles then smashed out a window and climbed through the window before surrendering to officers.”

Lt. Michael Whitmer observed what appeared to be a deceased woman sitting in a recliner in the residence, but because the doors and windows of the home had been padlocked, officers had to force their way into the residence through the front door before they could clear the residence.

The deceased female then was identified as Parton.

Styles was treated at the Newport Medical Center for cuts on her arms due to climbing through the window with broken glass, and then was jailed.

Fontes said tense, uncertain, dangerous situations such as the Thursday morning incident, “is why I am seeking to put protective ballistic shields in all of our patrol units in order to provide a much better level of protection for our officers. Thank you to the people who support law enforcement officers who are faced with dangerous situations as these, which are becoming more frequent in every community.”
