After calling 38 witnesses over the course of 11 days, Minnesota prosecutors neared the end of their case against former Minneapolis Police officer Derek Chauvin.

The defense is expected to begin calling its own witnesses on Tuesday, and closing arguments are expected for next Monday, Judge Peter Cahill said in court.

Chauvin, 45, has pleaded not guilty to second-degree unintentional murder, third-degree murder and second-degree manslaughter charges.

The prosecution’s case against Chauvin came in three distinct phases:

  1. What happened to George Floyd last May
  2. The Minneapolis Police use-of-force policy
  3. The medical analysis of why Floyd died

On Monday, Philonise Floyd testified at Chauvin’s trial that his elder brother George Floyd was a big mama’s boy who was distraught by her death in 2018.

“It was so unique how they were with each other. He would lay up onto her in the fetus position like he was still in the womb,” he said. “Being around him, he showed us how to treat our mom and how to respect our mom. He just — he loved her so dearly.”

The heartfelt testimony came as prosecutors sought to humanize Floyd, the 46-year-old Black man who died last May.

Also on Monday, an expert cardiologist testified that Floyd died from cardiopulmonary arrest caused by low oxygen levels brought on by prone restraint and positional asphyxia — making him the fifth doctor to say as much in the trial. In addition, a police use-of-force expert testified that Chauvin’s actions were unreasonable and excessive.
