The horses were found by a member of the public late on August 5 at a property about 60km north of Longreach, with initial investigations indicating the animals were killed sometime between Tuesday and Wednesday last week, police said.
The owner of the property was not home at the time of the incident.
Police said they arrested and charged a 49-year-old Mount Isa man on Thursday as part of the investigation into the horse deaths.
The man has been refused bail and will face the Mount Isa Magistrates Court on Friday charged with one count of injuring animals.
Police said last week that colts, mares, pregnant mares, geldings and mares with foals afoot died as a result of multiple gunshot wounds.
Detective Sergeant Allan Cook said the impact of such an incident is damaging to the local community.Jump to next article
