BRIGHTON, Colo. (AP) — Edited by porsi. Turn for overnight movement in new cycle.

Prosecutors were set to call their first witnesses Thursday in the trial of two Denver-area police officers charged in the 2019 death of Elijah McClain, a Black man who was put in a neck hold and injected by paramedics with a powerful sedative in a case that became a rallying cry for protests and spurred police reform.

In the first of several trials stemming from McClain’s death, opposing lawyers used opening statements Wednesday to paint contrasting pictures of the fatal struggle after he was stopped by police in Aurora.

Prosecutors said officers Randy Roedema and Jason Rosenblatt ignored McClain’s pleas of “I can’t breathe” and failed to follow their own training. Defense attorneys said the death was a tragedy but it was not the officers’ fault as they sought to shift blame to the paramedics.

The officers approached McClain, a 23-year-old massage therapist, as he walked home from a convenience store on Aug. 24, 2019, carrying only his phone and a plastic bag with three cans of iced tea. A 911 caller had reported him as “sketchy.”

If prosecutors can convince jurors the stop was unjustified, that would undermine any argument that McClain’s injuries were a result of the officers just doing their jobs.

Roedema and Rosenblatt are both charged with criminally negligent homicide, manslaughter and assault. They have pleaded not guilty but have never spoken publicly about the allegations. The trial is expected to last about a month.

A third officer and two paramedics are also charged in McClain’s death and are scheduled for trial later this year.

Officials have determined the sedative ketamine played a key role in McClain’s death, which fueled renewed scrutiny about the use of the drug for people considered to be acting erratically and led Colorado’s health department to limit when emergency workers can administer it. In 2020, neck holds by police were banned by the state’s Democratic-led Legislature.

Prosecutor Jonathan Bunge said the officers violated department policies by using excessive force against McClain, who was unarmed, and failing to deescalate the situation.

“Listen to Elijah’s words,” Bunge said as he replayed police body camera video of the episode. “When Elijah is on the ground handcuffed, he’s saying over and over and over again, ‘I can’t breathe. Please help me.’”

McClain threw up repeatedly after the neck hold and was drowning in his own vomit, according to Bunge. “He is drifting further and further toward death. The sedative is the last thing he needs,” the prosecutor said.

But Roedema’s attorney, Reid Elkus, said the officers’ actions were in line with department policies and their own training. McClain was stopped in a “high-crime area,” and officers repeatedly told him to halt before he complied, Elkus said, adding that they didn’t want to hurt him.

“Just because a tragedy occurred doesn’t mean criminality occurred,” Elkus said. He blamed McClain’s death on paramedics who later arrived on the scene and took control over his care.

“After being injected with ketamine, that’s when Mr. McClain’s pulse stopped,” Elkus said. “Mr. McClain died because paramedic (Jeremy) Cooper injected him with 1.7, 1.8 times the ketamine for someone his weight and size.”

Rosenblatt’s attorney, Harvey Steinberg, argued that the officers had no choice but to stop McClain after the 911 call. He added that McClain showed “continued resistance” after he was stopped and the officers were forced to respond accordingly.

“Please be fair and don’t allow emotion or sympathy come into it,” Steinberg told jurors. “And don’t let politics enter into this at all.”

McClain’s mother sat in the front of the courtroom for the opening statements. Sheneen McClain dabbed tears from her eyes when Bunge described how her son, who was often cold, was wearing a runner’s mask when he went to the store near his house before police stopped him.

Family members of the two officers also were present, as were other Aurora police.

The 12 jurors and 2 alternates selected Wednesday appeared to be mostly white.

Charges were not brought for two years after McClain died, by which time a national reckoning had begun over racial injustice in American policing following the murder of George Floyd by officers in Minneapolis.

In 2019, a local district attorney, Dave Young, called McClain’s death “tragic” but decided against prosecuting the officers largely because the coroner’s office could not determine exactly how McClain died.

A revised coroner’s report was issued in 2021, relying in part on information from a grand jury investigation. It found the cause of death was complications from ketamine after McClain, who weighed 140 pounds (64 kilograms), overdosed because he received a higher dose than recommended for someone of his size, pathologist Stephen Cina found.

Cina said he couldn’t rule out whether the stress of being held down by the officers may have contributed to McClain’s death.

Officer Nathan Woodyard, who is set to go on trial later this year, was the first to approach McClain and was soon joined by Roedema and Rosenblatt.

McClain, using earbuds, initially kept walking. Within 10 seconds, Woodyard put his hands on McClain, turning him around. As McClain tried to escape his grip, Woodyard said, “Relax, or I’m going to have to change this situation.”

The encounter quickly escalated, with officers taking him to the ground and putting him in a neck hold.

McClain suffered cardiac arrest on the way to the hospital and was pronounced dead three days later.

Prosecutors played numerous body camera clips including one in which they said McClain spoke his last words as Roedema jerked his arm up, popping a joint.

“Please help me,” McClain is heard saying. “Please help me.”
