Police have identified a woman shot dead early Friday morning at a home in Northwest Knoxville.

Officers responding to the shooting call about 5:30 a.m. at 3305 McKamey Road found Stacie Mundy, 38, of Knoxville, lying on the ground near the back door of the home, police said. She'd been shot at least once and was taken by ambulance to University of Tennessee Medical Center, where she was pronounced dead, according to a Knoxville Police Department news release.

Police said the preliminary investigation found Mundy was forcing her way into the home when the male homeowner shot her "in defense of his life." At least one other resident of the home knew Mundy at the time of the shooting, police said.

The homeowner and several other people at the home were taken to the Safety Building and interviewed by investigators. After reviewing the facts of the investigation with the District Attorney General’s Office, KPD said police declared the shooting a justifiable homicide and declined to file charges, releasing all the individuals.

Mundy was last arrested in Knox County in December with four other people when police received a tip that narcotics were being sold out of a room at the Best Western Inn, 5317 Pratt Road. She and four others were arrested and charged with possession of drug paraphernalia and manufacturing, delivery, sale and possession of Schedule I drugs after officers found they were holding 18 grams of suspected methamphetamine, 4 grams of suspected heroin and 68 Xanax bars.

She was arrested for simple possession/casual exchange, as well as possession of drug paraphernalia, in May 2016, and for possession of drug paraphernalia in March 2016.
