Snooping in your spouse’s e-mail could get you in a lot of trouble, one Michigan man has discovered.

Leon Walker faces felony charges for intentionally logging into his then-wife’s Gmail account on a shared computer. Leon Walker discovered his wife Clara Walker, who had been married twice previously, was having an affair with her second husband by reading her e-mails.

Leon Walker says that he was worried about the affair for reasons that went beyond simply cheating—he said that he was concerned about domestic abuse due to the ex-husband's history. The ex-husband had been arrested for beating Clara Walker in front of her young son. Leon Walker told the Detroit Free Press that he handed the e-mails to the boy’s father, his wife’s first husband. Leon Walker was arrested after his wife learned that he had been in her e-mail account.

Leon Walker is being accused of breaking a law that’s used to prosecute identity theft. He has been charged with felony computer misuse, and faces up to five years in prison if convicted. His trial begins February 7.

The Walkers finalized their divorce this month. The case is bringing up questions of privacy between a married couple and a shared computer.
