Hero Down: Crossville Police Department K9 Mattis Succumbs To Illness

Crossville, TN – Crossville Police Department (CPD) K9 Mattis died on April 13 after battling an incurable illness, according to his department.

The seven-year-old shepherd-Malinois mix was taken to University of Tennessee (UT) Veterinary Medical Center earlier that day due to an ongoing illness, the CPD said in a press release on April 14.

“K9 Mattis, unable to recover from his illness, was put to rest shortly after arriving, to end his pain and suffering,” the police department said.

The exact nature of his medical emergency was not immediately released.

“It is with saddened hearts that the City of Crossville police Department announces the final End of Watch Call for K9 Mattis, a six-year law enforcement veteran,” the CPD said. “A sincere thank you to Upper Cumberland Veterinary Clinic, UT Veterinary Medical Center and Yeargan Pet Cremation Services for their care during this difficult time.”

K9 Mattis began training alongside his human partner, CPD Lieutenant Jonathan O’Neal, in July of 2017.

The duo started patrolling the streets later the same year.

They were chosen as Officer of the Month in July of 2019, WATE reported.

“Serving as a K9 patrol with the Crossville Police Department, K9 Mattis has had a distinguished service history, always exceeding expectations and performing his important mission with the utmost reliability and drive,” the department said.

“Thank you K9 Mattis, your watch is over. Good Boy!” the CPD concluded.

More than 100 people offered their condolences to Lt. O’Neal and the CPD in response to the department’s announcement.

“Rest easy, good Mattis. Many thoughts and prayers are sent to your partner and family, as well as the Crossville PD,” one message read.

“O’Neal know that your partner knew you were the best just as you knew he was too,” another person wrote.

Our thoughts and prayers are with the Crossville Police Department and Lt. O’Neal in the loss of K9 Mattis.
