DUNCAN, Okla. - Charges have been filed against the former Stephens County deputy who's K9 officer died while in his care.
Matthew Peck is facing charges of one count of animal cruelty Monday.
Court documents outline details of what investigators believed led to the death of Bak.
Documents state, on August 3, "Peck was called to the scene of a traffic stop where Bak was used" and "When Peck returned home, he left Bak in the vehicle for approximately 38 hours with no water, food or cool air."
On August 5, "Peck returned to his vehicle and found his K9 partner dead inside and immediately notified the undersheriff."
Court documents also go on to state, when investigators approached Peck's deputy unit, "there was a very noticeable smell, recognized as a decomposing animal" and determined the dog "died from a heat stroke."
NewsChannel 4 tried contacting Peck but, so far, have not heard back.
