Police in Wisconsin are trying to figure out who's responsible for torturing some deer.The dead animals were found on a farm--after they were run down by snowmobilers.The Department of Natural Resources says it appears the deer were rounded up and then run over.Ted Dremel says, "Many of them had broken legs and hair and what not were missing off the deer. You could see where the snowmobile tracks rode right over the top of them."Three were found dead in the field.A fourth was found alive, but had broken legs and had to be put down.A fifth was found dead, its body tied to a tree.Investigators think three or four people are to blame but no arrests have been made.
