'I can't breathe! Help me! I'm choking on my blood!'

These were among the last words uttered by Sgt James Brown, 26, before he died in 2012 while serving a two-day sentence for a DWI incident at the El Paso County Jail.

The station KFOX14 this week obtained a graphic video showing what happened to the active-duty soldier from Fort Bliss before he passed away while in custody.

Brown, a decorated soldier who served two tours of duty in Iraq, left his wife and young child in July 2012 and self-reported at the El Paso jail for the weekend. He had no prior criminal history.

At the time of his check-in at the detention center, the 26-year-old notified officials that he was suffering from post-traumatic stress disorder.

Brown made a call to his mother from jail, telling her that county officials were trying to keep him detained for seven days instead of the agreed-upon two.

He asked Dinetta Robinson-Scott to send him money so he could pay a fine and leave the jail by Sunday night. She never heard from him again.

At some point between 8pm Friday and Sunday, Brown had a health crisis while sitting in his cell that caused him to bleed out of his mouth, nose and ears, according to lawyers representing his family.

A corrections officer at the jail turned on a video camera and started recording as a team of guards in riot gear stormed Brown's cell after he refused to communicate with them through the door.

In the disturbing jailhouse video, a group of guards in helmets are seen descending on Brown.

As they surround and obscure him from view, the inmate is heard crying out: ‘I'm choking on my blood!'

He then repeatedly states that he cannot breathe and begs for help. By the time the video is over, Brown will have repeated his complaint about his inability to draw a breath at least 20 times.

As he is taken to the infirmary, Brown collapses to the floor and is carried away by jail staff.

Brown is then strapped to a chair, injected twice with a sedative and has an anti-spit mask placed on his face.

‘Take it off! Take it off! Please, take the mask off! I cannot breathe,' he pleads.

In response to his entreaties, James Brown is given two half-full Dixie cups of water and is later allowed to wash pepper spray out of his eyes in the infirmary sink.

The muscular 26-year-old serviceman is eventually placed in a wheelchair and returned back to his cell, where he is placed naked on a cot.

Brown, who served two tours of duty in Iraq, stated in writing while checking in at the jail that he had PTSD

An autopsy concluded that Brown died from natural causes, namely, sickle cell episode

An unresponsive James Brown was then loaded onto a gurney, with a white blanket covering his privates, and taken to University Medical Center where he was pronounced dead.

An autopsy that was later performed on the inmate found that he died of sickle cell crisis - a condition that is caused by dehydration and stress.

Toxicology test results showed the man had no illegal narcotics in his system at the time of his death.

The family's attorneys said throughout the entire episode, no one bothered to call for an ambulance.

Brown's family insisted that the war veteran had no history of sickle cell incidents, and they are convinced that his death was caused by his treatment at the hands of the guards.

Brown's mother, Dinetta Robinson-Scott, last spoke to her son on the day he self-reported to jail on a Friday in July 2012

‘When a 26-year-old man checks into jail for a court imposed sentence on a Friday, and he leaves Sunday in a casket, something went horribly wrong there,’ said attorney B.J. Crow.

In a statement to the station, El Paso County Sheriff Richard Wiles called Brown's death 'an unfortunate tragedy' that, based on the results of an investigation, was the result of a pre-existing condition.

The Brown family have filed a federal lawsuit claiming excessive force and lack of proper medical care, among other violations.
