Man Kills Ex After She Announced Engagement to Another Man on Facebook

Sept. 1, 2010 — -- A North Carolina woman was fatally shot by her ex-boyfriend after she posted news of her engagement to another man on her Facebook page , police told ABC News.

Karen Ann Rooney, 63, was found shot several times in her Maysville, N.C., home Saturday night by a neighbor. With her was Peter Terrance Moonan, 62, who is believed to have killed Rooney before turning the gun on himself.

Rooney and Moonan had dated for 16 years prior to breaking up earlier this year.

According to Onslow County Sheriff's Maj. Donnie Worrell, Rooney was killed by her jealous ex-boyfriend whose rage may have been triggered by her Facebook page.

"[Rooney and Moonan] split up in February and since that time Rooney had met someone else," said Worrell. "And as of Aug. 1 she had changed her status to engaged."

"His family told us that he was having a hard time dealing with [news of the engagement] but that he had not shown any signs of anger or mental issues or anything else," he said.

"Everyone was surprised," said Worrell.

On Rooney's Facebook page , many of her friends had left celebratory messages on her recent engagement, one friend writing, "Congratulations!!! You guys make a great couple."

A photo on her Facebook page shows her posing with the man who would have been her future husband, William Jenkins.
