About fallen dairy princess Lori Esker, convicted in the "moomoo murder" of killing the fiancee of her former boyfriend. The 20-year-old Esker, Marathon County's reigning dairy princess until her arrest last September, was found guilty of using a belt to strangle Lisa Cihaski, 21, in the parking lot of a Howard Johnson Motor Lodge. Trial testimony disclosed Esker killed Cihaski to prevent her from marrying dairy farmer Bill Buss, 26. The murder has embarrassed state dairymen. "It's unfortunate the industry gets a black eye in the situation," said Dan Borschke, president of the Wisconsin Dairy Council.
