What started as a simple training exercise in Independence, Kan., turned into a two-mile chase involving five police officers, two highway patrolmen, concerned citizens, a horse-drawn wedding carriage, and Rocky, an 1,800-pound, 7-year-old Belgian gelding.

Before Rocky was captured on the grounds of a local high school with no injuries to horse or people, the carriage collided with a 2001 Mercury Sable, driven by Christina E. Tucker. The incident severed the driver's side mirror.
