The Mission Police Department and City Hall is now surrounded by black ribbon after they lost a 13-year-veteran in the line of duty Thursday evening.

Corporal Officer José Luis Espericueta was shot and killed when responding to a domestic violence call.

A woman called 911 said her son was threatening her with a gun and that’s when Mission police responded.

Espericueta was there as a backup to his fellow officers, but things quickly escalated.

“As the male subject was running towards the bell resort, he turned around and began discharging a weapon in the direction of Cpl. Espericueta striking him,” said Robert Dominguez, Mission Police Chief.

Espericueta was taken to a local hospital, but was pronounced dead shortly after.

The alleged shooter, Juan Chapa had a lengthy criminal history.

According to public records, he’s been arrested multiple times since 2007.

Police said Chapa was killed after officers shot back at him.

“Unfortunately, what we see in our communities not only here but throughout the nation is the number of officers killed in the line of duty- so we look forward to looking at this for the future,” Dominguez said.

The chief of police said the senior supervisor was loved by all his brothers and sisters in blue.

“We called him Speedy…you know here at the department with affection,” Dominguez said.

Espericueta had recently received The Meritorious Service Award after he entered a burning house to rescue an elderly man who was still inside and did not hesitate to save another life over his own.

And that’s how Chief Dominguez said he’ll be remembered.

“As we see today, this environment can be extremely dangerous our thoughts and prayers go out to his family first and foremost and to his brothers and sisters that had the privilege to work beside him for the last 13 years,” Dominguez said.

Texas Rangers are investigating this case.
