Before the jury headed to its deliberations, the prosecution remarked in its closing statement that Floyd died because Chauvin’s heart “was too small.”

Twelve jurors — six of them white, six Black or multiracial — are beginning deliberations in a city on edge against another round of unrest.

Minnesota Gov. Tim Walz declared an emergency in seven counties over the trial, enabling Ohio and Nebraska law enforcement to enter the state, according to reporter Tony Webster.

Judge Peter Cahill said Rep. Maxine Waters’ remarks about Floyd are not enough for a mistrial, but they could give grounds for an appeal, according to reporter Justin Baragona.

During closing arguments Monday, prosecutors contended that Chauvin squeezed the life out of Floyd by pinning his knee against Floyd’s neck last May, ignoring bystanders, his own training and common sense.

The defense argued that the now-fired white officer acted reasonably and that the 46-year-old Black man died of an underlying heart condition and illegal drug use.

Earlier Monday, prosecutor Steve Schleicher sought to convince the racially diverse jury that Chauvin squeezed the life out of Floyd by pinning him to the pavement for 9 minutes, 29 seconds, outside a corner market last May.

“His name was George Perry Floyd Jr.,” Schleicher said.

Floyd was “just a man, lying on the pavement, being pressed upon, desperately crying out. A grown man crying out for his mother. A human being.”

Schleicher finished his closing argument shortly after noon ET, with Chauvin’s defense attorney, Eric Nelson, beginning just before 12:45 ET.

Nelson, playing police body-camera video, noted that officers who first responded to the corner store where Floyd allegedly tried to pass a counterfeit $20 bill already were struggling with him when Chauvin arrived as backup.

The defense attorney also noted that the first two officers on the scene were rookies and that police had been told that Floyd might be on drugs.

“A reasonable police officer understands the intensity of the struggle,” Nelson said, saying that Chauvin’s body worn camera and his police badge were knocked off his chest.

Cahill opened the day’s court session by instructing the jurors on reviewing different types of evidence and told them that they will consider each charge against Chauvin separately.

For the defense, Floyd, who was Black, put himself at risk by swallowing fentanyl and methamphetamine, then resisted officers trying to arrest him — factors that compounded his vulnerability to a diseased heart and raise sufficient doubt that Chauvin, who is white, should be acquitted.

Each side pulled key testimony to support their narrative for what killed Floyd in a case that roiled America 11 months ago and continues to resonate. The anonymous jury will later deliver verdicts in a courthouse surrounded by concrete barriers and razor wire, in an anxious city heavily fortified by National Guard members and just days after fresh outrage erupted over the police killing of a 20-year-old Black man in a nearby suburb.

The attorneys aren’t limited by time, though legal experts say overlong arguments risk losing jurors’ attention and may be less effective. Prosecutors Schleicher and Jerry Blackwell shared the closing, with Schleicher leading off and Blackwell coming on for the last-word rebuttal of Nelson’s closing.

Chauvin, 45, is charged with second-degree murder, third-degree murder and second-degree manslaughter. Experts expect Schleicher to walk jurors through the elements of the charges. All three require the jury to conclude that Chauvin’s actions were a “substantial causal factor” in Floyd’s death — and that his use of force was unreasonable.

Schleicher reminded jurors of key testimony from myriad prosecution medical experts who testified that Floyd died of asphyxiation caused by being pinned to the pavement. He and Blackwell pointed to testimony from use-of-force experts who said Chauvin’s actions were improper, as well as Minneapolis Police Department officials saying they were outside his training.

Guilty verdicts must be unanimous, which means Nelson needed to raise doubt in the minds of just a single juror on the various counts.

Nelson also highlighted how the county medical examiner, Dr. Andrew Baker, did not conclude that Floyd died of asphyxia — putting him at odds with the prosecution’s medical experts, even though Baker did call Floyd’s death a homicide and testify that he believes Floyd’s heart gave out in part due to being pinned to the ground.

Nelson also reminded the jury of Floyd’s drug use, perhaps with the same language he frequently used during the testimony phase. Despite the long duration of Floyd’s restraint, he again portrayed Chauvin’s use of force as dictated by “fluid” and “dynamic” factors that shouldn’t be second-guessed, including the prospect that Chauvin was distracted by a threatening group of bystanders.
