A Wisconsin man was convicted of his wife's murder with evidence that included his search history of the ingredients used to kill her, Forbes reported.
On the morning of Julie Jensen's death "someone attempted to "double-delete" (apparently unsuccessfully) the computer's browsing history, which included a search for "ethylene glycol poisoning." She died from that method of poisoning.
In his appeal of the original conviction, Mark Jensen's claim his computer use should have been protected under the Fourth Amendment - unreasonable searches - was overturned. The court found his searches were the unreasonable ones.
His "home computer revealed Internet searches for botulism, poisoning, pipe bombs and mercury fulminate. A website was visited that explained how to reverse the polarity of a swimming pool -- the Jensens had a pool -- by switching the wires around, likening the result to the 4th of July. The State pointed out the absence of Internet searches on topics like separation, divorce, child custody or marital property," Forbes noted.
