A Collierville horse trainer who pleaded guilty to 12 counts of animal cruelty last year has been sentenced to house arrest for a year and fined $25,000. According to The Commercial Appeal, Circuit Judge Weber McGraw sentenced Jackie McConnell and two co-defendants on Tuesday. McConnell’s plea came after the Humane Society of the United States in 2011 shot video inside a stable showing caustic substances being applied to Tennessee walking horses’ legs and hooves, and the animals being beaten to make them stand. Jeff Dockery of Collierville pleaded guilty to three counts of animal cruelty and John K. Mays of Holly Springs, Miss., pleaded guilty to four counts of cruelty. Dockery was given three years’ probation and Mays has four years’ probation.
