Police officers started a manhunt for the suspect in a Colorado shooting on Sunday, June 6, in Pueblo that injured an off-duty firefighter after protecting a homeless man.

Detectives of the Pueblo Police Department identified the suspect in the Colorado shooting as Esteban Gallegos, 41 years old.

Because Gallegos is still on the loose, the department sought the public's help locating the suspect. The Colorado shooting that injured a firefighter adds to the recent shooting incidents in the United States. 

It can be recalled that a firefighter was killed, and another firefighter was hurt in a shooting incident in Santa Clarita, California after an off-duty firefighter opened fire in the Los Angeles Fire Station 81.

Colorado Shooting: Firefighter Injured After Protecting a Homeless Man

The shooting incident started when several off-duty firefighters in Pueblo, Colorado noticed a group of men harassing an individual.

According to a KRDO report, Pueblo Fire Union President Joey Gutierrez said the firefighters were reported to wait for their pizza to arrive outside the union building on the 100 block of Nort Main Street.

Fox News reported that a group of men went out of a bar and started harassing a homeless individual with mental health problems. 

The firefighter went to the aid of the homeless man and asked the individuals to leave the man alone. The individuals who were not identified by the authorities abided by the firefighters' request and immediately left the area.

After the firefighters went back to their original place waiting for their food, a sedan parked outside the nearby establishment fired several rounds towards the direction of the firefighters.

Due to the incident, officers who arrived at the area around 12:55 a.m. on Sunday, June 6, said a firefighter sustained a gunshot wound in the leg. 

Although the authorities did not identify the injured firefighter, officers noted that the male victim was transported to a hospital and was treated for non-life-threatening injuries. Additionally, Fox News pointed out that the male firefighter is now recovering and doing well.

Colorado Shooting Suspect still on the Loose

Although police did not yet catch the 41-year-old Colorado shooter, an arrest warrant against Gallegos was already issued. 

Detectives with the Pueblo Police Department Crimes Against Persons Section conducted the investigation that led to the discovery of Gallegos being the prime suspect in the Colorado shooting. 

Authorities believe that the vehicle utilized by Gallegos was a 90s model Buick product. 

Because of what happened, the Colorado shooting suspect is facing one count of first-degree assault and eight counts of attempted first-degree murder.

Details of whether Gallegos was part of the people who harassed the homeless man were not provided by the authorities. 

Meanwhile, the Pueblo Fire Department noted that they still cannot give details right now because the criminal investigation is still active.
