SAN ANTONIO (KTSA News) — Bexar County sheriff Javier Salazar provided more details about the Friday night chase that ended in the death of a K9.

Salazar said at a news conference Monday morning the chase began in Karnes City at around 9:30 p.m. when police there tried to stop Matthew Mireles for speeding.

He refused to stop.

Salazar said Mireles led police and eventually DPS on a chase through Kenedy along U.S. 181 to Interstate 37 and then Loop 1604.

Deputies tried twice to deploy spike strips to stop Mireles, but both attempts failed.

A few minutes later, he was seen from an overhead helicopter shooting at deputies and troopers over his shoulder while driving.

Mireles then got out of his car and then started walking away along Loop 1604.  The vehicle K9 Chucky was in was right behind his car.

The deputy and Chucky were walking behind Mireles to keep up with him.

About 20 minutes after stopping, Chucky tried to take Mireles down, but Salazar said Chucky lost grip on the suspect and was shaken off.

Mireles then shot shot Chucky.

Deputies and troopers on the scene shot at Mireles and Chucky — despite being wounded — tried to take Mireles down again.

Chucky died shortly after.

Salazar said Mireles has a felony warrant out of Harris County, though he did not immediately have details on what he was wanted for at the time of the news conference.

The sheriff also mentioned that Mireles was reportedly streaming parts of the chase on Facebook Live.

Salazar stated K9 Chucky was not wearing a vest at the time of the shooting because the deputy did not have enough time to put the vest on, since he was in the primary car of the chase.

The sheriff said the initial review of the case shows deputies and troopers followed proper procedure during and after the pursuit.
