A rollover on Interstate 90 left one world champion show horse dead Saturday morning.

Mower County Sheriff Terese Amazi said deputies responded to a report of a crash on Interstate 90 at mile marker 186 near the Elkton exit at about 10 a.m. Saturday. The driver, Joel Jacque, of Port Washington, Wis., lost control of his truck and trailer carrying the horse and rolled the vehicle. The horse inside the trailer sustained numerous injuries and was unable to stand. Amazi said veterinary staff was called to the scene and the horse was put down because of its injuries.

The horse, L-T-Kid, was a quarter horse born in 2000 and a 2002 halter stallion world champion, according to owner Gene Wilson, of Estherville, Iowa. Jacque had rented the horse for breeding. L-T-Kid was insured for $60,000.

After the horse was put down, a 76-year-old driver ran over the horse’s neck, according to Amazi. The driver was going 60 mph in a 70 mph-zone but there were several tow trucks and police cruisers in the area. The driver initially stopped after hitting the horse, but tried to drive away from the scene, causing police to stop the vehicle. Amazi said the driver told deputies she didn’t think she had to slow down. The driver will have her license re-examined.
