A corrections officer is facing bigamy charges after authorities said a Washington woman using Facebook discovered that she and a potential “friend” were married to him at the same time.

According to charging documents filed Thursday, Alan L. O’Neill married a woman in 2001, moved out in 2009, changed his name and remarried without divorcing her. The first wife first noticed O’Neill had moved on to another woman when Facebook suggested the friendship connection to wife No. 2 under the “People You May Know” feature.

“Wife No. 1 went to wife No. 2’s page and saw a picture of her and her husband with a wedding cake,” Pierce County Prosecutor Mark Lindquist told The Associated Press.

Wife No. 1 then called the defendant’s mother.

“An hour later the defendant arrived at (Wife No. 1’s) apartment, and she asked him several times if they were divorced,” court records show. “The defendant said, ’No, we are still married.’”

Neither O’Neill nor his first wife had filed for divorce, according to charging documents. The name change came in December, and later that month he married his second wife.

O’Neill allegedly told wife No. 1 not to tell anybody about his dual marriages, that he would fix it, the documents state…

“Facebook is now a place where people discover things about each other they end up reporting to law enforcement,” Lindquist said.

Har. What goes around, comes around. Just 100 times faster in cyberspace.
