Diesel

K9 Diesel succumbed to injuries he received while attempting to apprehend a suspect with felony warrants at the 3300 block of 4th Avenue in Chattanooga.

Officers were responding to a domestic disturbance call, and the armed subject refused to exit the house. When K9 Diesel was deployed to execute a search for the subject, he suffered severe lacerations from broken glass on both hind legs, severing an artery and his Achilles tendon.

Despite immediate life-saving treatment, K9 Diesel's injuries were too severe, and he was humanely euthanized on September 17, 2025.

The suspect was apprehended a few weeks later and was charged with aggravated assault and false imprisonment.

K9 Diesel had served with the Chattanooga Police Department for one year and five months.

K9 Diesel was named in honor of U.S. Marine Corps Sergeant Carson Holmquist, one of Chattanooga’s Fallen Five. During the 2025 USPCA Region 22 K9 Trials, K9 Diesel earned 1st place in Suspect Box Search and 2nd place in Narcotics Detection, qualifying for the national competition.

Why was the idiot not charged with the murder of a LEO???? It’s no different than killing a human. He was trained hard, worked hard and became a TRUE HERO, saving other LEO’S and the public. God Bless and Godspeed.
