Moment Arizona police sniper wounds a DUI suspect who ran from cops with a handgun before being shot dead by officers after opening fire

This is the dramatic moment a police sniper wounded a suspect, before other officers shot and killed him when he opened fire on authorities. 

Tobin Pico was pulled over by Marana police in Arizona around 5:30 p.m. on February 10 at a gas station on the corner of West Ina Road and Old Father Drive.

As officers arrested Pico, he escaped and pulled out a weapon as cops gave chase. 

At one point, Pico walked alone behind a building. A police sniper set up and unleashed three shots at the suspect. The first two missed, but the third hit and sent him to the ground withering in pain. 

Pico, despite being shot, got up seconds later and went around the corner of the building. He was met by other officers who demanded he drop his gun. Instead, Pico opened fire leading to a gun battle where police killed him in a barrage of bullets.

Authorities have launched an investigation into the fatal shooting to determine if police procedure was followed. It's unclear if the officers involved remain on duty during the investigation. 

After conducting a DUI test, officers arrested Pico on suspicion of aggravated DUI, reported the Arizona Daily Star.

When officers tried to put handcuffs on him, he ran and fled through traffic.

Video released by the Pima Regional Critical Incident Team shows Pico pulled out a handgun during the chase.

While crossing the median, Pico fell and dropped the gun he was carrying.

'Gotta gun! Gun! Gun! Gun!' an officer is heard shouting as he chased Pico.

After Pico picked the gun back up, he continued running with the weapon. Officers repeatedly told Pico to stop and drop his weapon. 

'Stop right now or I'm going to shoot you,' one officer said as Pico ran down a path behind a building.

Officers fired at least a dozen shots, some hitting the suspect, causing him again to fall to the ground

'Stop, drop the gun. Drop it. Drop the gun. Drop it,' another officer said during the foot pursuit. 

The Pima County Sheriff's Department Survey Air Unit was called and drone footage shows Pico walking along a path along the Canyon Del Oro Wash. There Pico was seen firing off his gun.

A police sniper began getting into place to shoot at Pico as he continued down the path. 

Pico then walked toward an occupied parking lot with open businesses in the 6900 block of North Thornydale Road. 

As the suspect was walking behind a building, a sniper fired off three rounds at Pico from around the corner - hitting him once. The shot didn't kill Pico as he was able to get up after a few seconds and move close to the building. 

There, another set of officers fired at Pico, who fired back, starting a shootout between him and the cops.

As an officer fired off multiple shots at Pico, another cop is heard telling the suspect to drop his weapon. Video shows police unleashing a dozen shots at Pico as he was hit and fell to the ground again - this time fatally wounded.

According to Pico's obituary, he left behind a pregnant girlfriend who was carrying their soon-to-be-born daughter

Police said once the suspect was struck, officers provided aid until paramedics arrived. However, Pico was pronounced dead at the scene.

The officers who fired their weapons during the incident have been identified as Officer Brad Gill, a 12-year veteran; Officer Jacob McCarthy, a 6-year veteran; and Officer Max Wozniak, a 7-year veteran. 

According to Pico's obituary, he left behind a pregnant girlfriend who was carrying their soon-to-be-born daughter. 

Pima Regional Critical Incident Team is investigating the incident and Marana police are conducting their own investigation to determine if department policies were followed.
