John Myers, of Bloomfield, N.J., set the self-timer on his camera and hustled into the frame with his wife and two children Saturday. While their backs were turned, someone grabbed their bag, which held Myers' wallet and other items.
After Myers discovered the bag missing, he checked his camera.
Sure enough, the image showed a man picking up the bag.
Myers told the Wisconsin State Journal that he showed the photo to officers, who recognized the man.
When officers found him, he was still carrying the bag.
The suspect pleaded not guilty Tuesday to misdemeanor theft.
