BOULDER COUNTY, Colo. - The Boulder County Sheriff's Office said Friday that tainted meatballs that someone left for dogs in a private park last month contained a common rat-poison ingredient.
Sheriff's Cmdr. Heidi Prentup said testing confirmed the meatballs contained Brodifacoum, "an active ingredient in two of three commonly sold rodenticides."
Brodifacoum is an anticoagulant poison that kills rodents by preventing blood clotting, causing the creatures to bleed to death.
Raw meatballs were initially found on the night of April 14 in a neighborhood park located at 5150 Buckingham Rd. in Gunbarrel. They contained green chunks of rat poison, according to the Sheriff's Office. More meatballs were found in the park over several days.
At least three dogs have been treated by veterinarians after consuming the toxic meatballs. Pet owners have been warned to be attentive to what your animals are eating on as you walk them in the area.
Prentup said the investigation continues and investigators are working to locate the person who made and distributed the meatballs in the park.
A reward has grown to $4,625 for information leading to the arrest and conviction of the person responsible for these crimes.
