MINNEAPOLIS — Jury selection in the trial of a former Minneapolis officer accused in the death of George Floyd was put on hold Monday while an appeals court considers whether to reinstate a third-degree murder charge against him.

Derek Chauvin is already facing a second-degree unintentional murder charge and a manslaughter charge. He has pleaded not guilty.

Floyd, who was Black, died May 25 after Chauvin, who is white, pressed his knee on Floyds neck while he was handcuffed on the ground, pleading that he couldnt breathe. Floyd’s death sparked months of mass protests nationwide over police brutality and race. In Minneapolis and some other areas, the civil unrest spiraled into violence. Other former officers who were present when Floyd died will face trial later this year.

Here’s a look at why the charge plays such a large role in the trial.

WHAT DO THE DIFFERENT DEGREES MEAN?

The degrees denote the seriousness of a crime. The more serious the crime, the higher the benchmarks that prosecutors must prove beyond a reasonable doubt to convict. First-degree murder is the most serious and results in life in prison if convicted. To convict, prosecutors must prove either that the act was pre-planned or that other major crimes were committed with it, among other things. Second-degree murder in Minnesota can be intentional or unintentional,” which is the charge Chauvin faces, and is punishable by up to 40 years in prison if convicted.

Third-degree murder would require a lower standard of proof than second-degree. To win a conviction, prosecutors would have to show only that Floyd’s death was caused by an act that was obviusly dangerous, though not necessarily a felony. That would result in a maximum sentence of 25 years.

But there are caveats. Chauvin has no criminal history, which means he will probably end up serving about 12 1/2 years whether he is convicted of second or third-degree murder. Manslaughter, the least serious charge but also the one with the lowest burden of proof, means a maximum of just 10 years behind bars if convicted. For those seeking justice in Floyd’s death, anything less than murder is likely to feel like injustice.

WHY WAS THAT CHARGE DISMISSED TO BEGIN WITH?

Chauvin’s lawyer sought to dismiss the charge, arguing there was not probable cause to charge him with third-degree murder. A Minnesota judge ruled last October that third-degree murder under Minnesota law requires proof that someones conduct was eminently dangerous to others, plural, not just to Floyd. The judge said there was no evidence that Chauvin endangered anyone else and threw out the charge. Prosecutors appealed.

WHY PUSH TO HAVE IT ADDED AGAIN?

Very simply, reinstating the count could i ncrease the prosecutions odds of getting a murder conviction in what will be one of the highest-profile police trials in the U.S.

CAN HE BE CONVICTED WITHOUT IT?

Yes. But it’s not going to be as easy as some might think. Even with the bystander video that showed Chauvin pressing his knee into George Floyds neck and ignoring the mans pleas, legal experts say the case isnt a slam dunk.

Its hard not to watch the video and conclude that the prosecutors will not have any trouble with this case, said Susan Gaertner, the former head prosecutor in neighboring Ramsey County. But its not that simple.

The trial will come down to two key questions: Did Chauvins actions cause Floyds death, and were his actions reasonable?

The second-degree murder charge requires prosecutors to prove Chauvin caused Floyds death while committing or trying to commit a felony in this case, third-degree assault. Prosecutors dont have to prove that Chauvin was the sole cause of Floyds death only that his conduct was a substantial causal factor. The manslaughter charge has a lower bar, requiring proof that Chauvin caused Floyds death through negligence that created an unreasonable risk, and consciously took the chance of causing severe injury or death.

Chauvins attorney, Eric Nelson, argues in court documents that Floyd likely died from fentanyl he consumed, or a combination of fentanyl, methamphetamine and underlying health conditions not as a result of Chauvins knee on his neck.

WHAT HAPPENS NOW?

Prosecutors filed a request with the state’s Court of Appeals to put the trial on hold until the issue is resolved. They worry, in part, that they could lose the chance to try Chauvin later on the third-degree murder charge if the current trial goes forward while the appeal is ongoing.

The judge overseeing the case, Peter Cahill, sent potential jurors home for the day, while prosecutors tried to contact the appellate court. Cahill took a recess to give the Court of Appeals time to respond, but planned to bring attorneys back into the courtroom Monday afternoon to deal with other matters.

Cahill said he would proceed with the trial unless the higher courts told him to stop.
