I think I found some proof as to a group that may be connected.

These people have got to be evil criminal masterminds to come up with such a devious tag as the smiley face as their signature. And given how prolific their signature mark is- they must have legions of followers throughout the country willing to do their bidding.
I did a wikipedia search of the notorious smiley faces and found some very shocking references. This goes back decades!
Smiley face stickers were the calling cards of the werewolf in "The Howling" in 1981. Obviously these killers are demonic.
Smiley faces are the symbol of "acid house" music- the hypnotic music played at Raves. Smiley faces were found craved in tabled in the UK in the 1980s. Hmmm, hypnosis. Maybe that's why these hasn't been anything except for booze in the victims blood. They were hypnotized.
In the 1995 film Virtuosity a smiley is used to mark a restaurant where the virtual serial killer "Sid 6.7" was hiding.
In Blazing Saddles, when Hedley Lamar is enlisting his criminal army, the KKK members wear smiley faces and have a nice day on the back of their sheets.
The film Forrest Gump (Robert Zemeckis, 1994) comically featured the smiley being "invented" when the main character wipes his mud-covered face off with a yellow t-shirt, and says "Have a nice day", inspiring a struggling businessman with the makeshift design.
And finally, to really show how evil these bastards are http://en.wikipedia.org/wiki/Image:Bon_Jovi_Have_a_Nice_Day.jpg
Serious stuff, these evil Smiley Faces are everywhere. The Feds shouldn't be going after terrorists- they should devote their resources to stamping out Smilies!
