MEMPHIS, Tenn. — It appears a man who shot and killed a woman at a Memphis home Thursday might have done so in self-defense.

Police found the man, who has not been identified, standing in the yard at 3416 Wythe holding a gun and wounded.

Inside, a woman who had been shot several times was found dead.

Police say a man and his girlfriend were fighting.

At some point the girlfriend’s sister, 31-year-old Melania Cook, came to the house.

Police say Cook pulled a gun; the man grabbed his gun, and both fired.

The man was taken to the Regional Medical Center to be treated for his wounds.

According to the Memphis Police Department, “evidence was presented to the District Attorney General’s Office, who declined prosecution at this time.”

Police told us the have not responded to any domestic violence calls at the home previously.

WREG spoke with the man off-camera Friday, who said Cook pointed a gun at his head.

“What I can tell you is that no one has been charged at this point. It is still under investigation. Statements are still under investigation, and when the police have finished their work, they’ll present what they have to us, and a decision will be made at that time,” said Deputy District Attorney General Jennifer Nichols.

WREG spoke with a neighbor who was relieved to hear that the man would not be charged.
