A central Pennsylvania man has been convicted for beating his wife when she didn't address him as "sir" in front of their kids.
Lancaster County prosecutors say 49-year-old Dan Kirby Kopp of Ephrata routinely beat his wife with a wooden paddle or his hand when he believed she was disrespectful.
The Intelligencer Journal/Lancaster New Era reports ( http://bit.ly/15o3Fex ) that Kopp's wife used an iPhone to videotape a September 2012 beating that was shown to jurors. The video shows the 6-foot-5, 230-pound Kopp beating her with a paddle for not addressing him with "yes, sir."
Kopp was convicted of misdemeanor stalking and harassment. He was sentenced Tuesday to one to 23 months in prison and one year of parole and has been ordered to stay away from his now-estranged wife.
