Rule Number One: Do not leave search terms like "ethylene glycol death human" on your computer.

James Keown poisoned his wife with Gatorade and antifreeze over a period several months before administering a final, fatal does on Sept. 4, 2004. He killed her for her $250,000 life insurance policy because he was deeply in debt.

The defense told the jury that Julie Keown could have committed suicide or accidentally ingested the chemical. No antifreeze was found in the Keowns' home. However, a computer expert told the court that two days before Julie Keown entered the hospital the first time, James Keown's computer showed he did a search using the words "ethylene glycol death human."

Keown has been sentenced to life imprisonment without parole.
