Colorado Man Fatally Beat Roommate’s Dog And Dismembered Another

Published: September 21, 2020 at 06:41 AM Author: Penny Eims

Two dogs suffered a horrific death when a 30-year-old Colorado man attacked them. Matthew Stephen Dieringer was arrested by Arapahoe County Sheriff’s Office deputies for beating one of his roommate’s dogs to death and disemboweling the other.

Dieringer faces two counts of felony aggravated cruelty to animals and he must receive the maximum punishment! Please add your name to the petition. We will be sending your signatures and comments to officials, along with our letter requesting that this man be held accountable for his deplorable actions.

Matthew Stephen Dieringer stole the life of an Australian cattle dog named Suka, who died from blunt force trauma, and Hayoka, a mixed breed dog who was disemboweled.

These dogs did nothing to warrant the cruelty they experienced – clearly, this man is violent and dangerous, and he must be put away. The authorities are taking this case seriously and have commended the public for their part in helping make Dieringer’s arrest possible:

“The Teller County Sheriff’s Office would like to thank the public for their interest in this case and vigilance in watching out for Mr. Dieringer. We would also like to thank our law enforcement partners at the Arapahoe County Sheriff’s Office and the FBI Safe Streets Task Force. It is times like these that remind us all that all life is precious and partnerships with our community and law enforcement partners creates opportunities for great outcomes.”

Suka and Hayoka deserve justice. Please add your name to the petition to help the judge understand that we are tired of animal cruelty! This despicable individual must receive the maximum punishment.
