A follow up the first part of the story which you can read in full here;

A three year old from Tennessean, shot herself in the abdomen with a handgun and died; the child had been playing a Nintendo Wii video game, County Sheriff Terry Ashe said. The game’s controller was shaped like a gun that looked very similar to the real handgun, which her stepfather had put on a table in the living room. Ashe said the girl pulled the gun off the table and it went off.

The gun which many believed including myself was something like this:

Ending up looking nothing like the regular store bought wii gun’s:

The gun above is the Wii gun, and the gun below is the actual gun which the three year old mistook for the Wii gun. The Wii gun pictured above is manufactured by HAIHONGCHANG Electronics Company in China. The gun can be bought off ebay and other online stores for about $7- 15 dollars. It was also previously stated in the first article that the father had been using the gun to scare away dog’s, but a recent update states that he was using it for trespasser’s:

Cheyenne’s stepfather, Douglas Robert Cronberger, said he believed someone was trespassing on their property, so he stepped outside with his semi-automatic gun. When he returned inside, he placed the gun on a living room table
