Earlier this week a 5-year-old boy was playing with his Crickett-brand "My First Rifle" when it went off by accident, killing his 2-year-old sister.

Many online, reacting to the story, were horrified, not only because of the accident, but also the way Crickett Rifles marketed their rifles to children.

"The rifle used in the accident is a Crickett designed for children." Imma just let that sit there. #guncontrol

As of Friday morning, Cricket's website has disappeared, replaced with a Linux Test Page.

Its Twitter account has vanished, as well.

According to Topsy.com, a Twitter archiving service, Crickett's last tweet was sent eight days ago.

Twitter users quickly dug up anything and everything they could about Crickett Rifles in the days following the accident.

The section of Crickett's website that recieved the most attention was its "Kids' Corner," which featured pictures of children using their rifles.

You can still buy Crickett rifles at Walmart, although it's in-store purchase only.

Here's a TV spot for Crickett Rifles, advertising that they make rifles "for girls and even mom," ending with the tagline: "Target shooting is fun!"
