Let this be a lesson to all:

A man who walked into a Wal-Mart covered in blood and bought garbage bags Friday was charged with murder after authorities found a stabbed body in a trash bin.

Wal-Mart workers called deputies after a blood-soaked man walked into the store and bought some clothes, bandages and trash bags around 4 a.m. He paid with a $100 bill that also appeared to be bloodstained, they said, and drove off in a pickup.

Everyone knows Wal-Mart is a good resource for anything, but if you are going to use it after you've killed, at least clean up before you go there first. duh.
