A horse was euthanized and its rider hospitalized after they were hit by a vehicle Monday evening in Florence, police said.
The crash happened about 6:40 p.m. at Colorado 115 and County Road 117, police said. The rider, a 54-year-old woman, was severely injured and taken to a hospital.
A large-animal veterinarian "determined that the horse was too seriously injured and had to be euthanized," police said.
The driver of the vehicle, Michael Dylan Brookshire, 23, of Penrose, was arrested on suspicion of vehicular assault, animal cruelty, driving under the influence of drugs and failing to drive in the designated lane, police said.
Brookshire was booked into the Fremont County jail.
