A 38-year-old Denver man has been arrested and charged with fatally shooting a Westminster man at a Thornton bar last week after a late-night melee quickly escalated to gunfire.

Thornton Police Department spokesman Sgt. Matt Kandt said the incident began shortly before 1:30 a.m. Feb. 24 at Chamucos Bar, 8651 Washington St., when a brawl broke out among several patrons, including a group of three men and two women.

As that group was being escorted out of the bar, Kandt said one person pulled out a weapon and fired shots inside the bar before fleeing the scene.

An unknown number of bullets struck 45-year-old Jose Antonio Horner-Torres of Westminster, who was taken to a local hospital for treatment. Horner-Torres later died from his injuries on March 1.

The alleged shooter, Mario Oliveros, was later identified and arrested that same day without incident at a residence in the 9100 block of Gale Boulevard in Thornton.

Oliveros, who has been held at the Adams County Detention Facility since his arrest, was charged on Feb. 1 with two counts of felony first-degree murder in Horner-Torres’ death, five felony counts of attempted first-degree murder for attempting to shoot other bar patrons, and one felony weapons possession charge by a previous offender.

Thornton Police Department spokesman Matt Barnes said on Monday that Oliveros’ mugshot was being withheld for “photo line-up considerations.”

Adams County District Attorney’s Office spokeswoman Sue Lindsay said Oliveros is scheduled to appear for his preliminary hearing on May 10 at the Adams County Justice Center, 1100 Judicial Center Drive in Brighton.
