Scott County jurors on Monday convicted a 47-year-old man of second-degree murder in the 2008 killing of his wife, Ruth Anne Maddox, after which he tried to cover his tracks by posing as her and pretended to hop a plane out of town.
Charles "Tony" Maddox took the stand last week and told jurors that although he did kill his wife at their Prior Lake townhouse and tried to cover it up, it was in self-defense.
Ruth Anne Maddox, 45, had filed for divorce. The day before her death, she had told Tony Maddox that she was going to show his mother sexually explicit e-mails that he had written, soliciting sex from men online, prosecutors said.
The jury found that Maddox killed his wife and packaged her body in the garage.
Police arrived with a search warrant and found her body just after 3 a.m. on Nov. 12, 2008, after being called by friends and family members when the Shakopee Valley News reporter didn't show up for work.
E-mails and texts laid a path for investigators as they developed Tony Maddox's motive and tore apart his alibi. They tracked his movements as he tried to mislead police -- including wearing a disguise to pose as his wife at the airport.
Maddox even used both his and his wife's cellphones to send texts as if they were communicating about her leaving, Assistant Scott County Attorney Neil Nelson said.
Police and attorneys said Internet and social networking sites being increasingly used in family law and criminal court cases.
