PRAIRIE DU CHIEN, Wis. (AP) -- Wild pigs were present in western Wisconsin before authorities say a Texas man brought them here.
That's according to Mark Peterson, an attorney for Robert Johnson.
State investigators have accused Johnson of bringing 31 wild hogs from Texas to Crawford County in 2002 and starting a wild-pig population that has cost farmers thousands of dollars in crop damage.
Wisconsin Department of Natural Resources warden Mike Cross told Peterson under cross-examination Friday that he investigated reports of a man claiming a wild pig jumped his fence and bred one of his sows six or seven years ago.
Peterson said that would've been in 1999 or 2000.
Peterson also tried to show witnesses were drunk when Cross interviewed them.
