A British man killed his estranged wife after learning that she changed her marital status to single at her Facebook account.

”Richardson became enraged when Sarah changed her marital status on Facebook to single and decided to go and see her as she was not responding to his messages,” Cortese said.

”He gained entry by breaking the front door window and made his way into the property.

”Once inside, he found Sarah in her bedroom and subjected her to a frenzied and brutal attack with a knife and then attempted to take his own life.”

This incident is a lesson to married ones who are trying to act like unmarried by setting the marital status in Friendster, Facebook, MySpace or any social networking sites to “single” because it will really cause trouble between the couple especially if their husbands or wives are jealous.
