KENOSHA, Wis. — A couple accused of starving horses at their Pleasant Prairie farm could face dozens of new charges.

David White and Paula Moctezuma-White were in court Wednesday on charges they mistreated animals on their farm, leading to the animals' deaths.

The couple pleaded not guilty. They had each initially been charged with one count of animal mistreatment causing death. Four more were added Wednesday.

The Kenosha News ( reports the couple's attorneys argued the felonies should be reduced to misdemeanors or dismissed entirely.

But the court commissioner agreed with the state and kept the felony charges.

Assistant District Attorney Jennifer Phan says prosecutors may file as many as 69 more felonies for the deaths of the 55 horses, 12 goats and two cows whose carcasses were found on the farm.
