One of the victims, who asked not to be identified, told WHBQ that his niece, who was visiting from Florida, took his gun and scared off the bold criminal after she saw that her husband was in trouble.
“She’s bold," he said. "She ain’t scared of nothing.”
In the video, the suspect has his right hand in his waist band as he stands behind the woman's husband. The victims said the man's hand was on a gun.
Memphis police said Sunday afternoon the man in the blue jacket came to the Whitehaven home and asked to use one of the victims’ phones and then asked for a ride.

While the incident was unfolding outside the house, the woman and her uncle reportedly were inside the house.
Police said that after the woman saw her husband in trouble, she came out the front door with a gun and fired a warning shot.
The uncle told WHBQ: "She said she didn't want to kill him, but when he fired back at us after she fired the warning shot, she said she was trying to hit him then but didn't."
Memphis police told WHBQ that the suspect ran toward the back of the house before getting away.
Police said they are reviewing this surveillance video to get a positive ID on the suspect. If you have any information on who that suspect may be, call CrimeStoppers at 901-528-CASH.
