The three other former police officers who were involved in the killing of unarmed Black man, George Floyd -- have now all been charged.
Thomas Lane, 37, J. Alexander Kueng, 26, and Tou Thao, 34, now face two charges each of aiding and abetting their fellow former officer Derek Chauvin.
Chavin's charge of third-degree murder was also elevated to second-degree murder.
The news was announced by Minnesota Attorney General Keith Ellison said Wednesday.
"I believe the evidence available to us now supports the stronger charge of second-degree murder," Ellison said. "I strongly believe these developments are in the interest for justice, Mr. Floyd, our community, and the state."
"These officers are complicit by their silence, but we now know based on the audio from their body cam that they also are accomplices because their failure to act when they knew that he did not have a pulse," Benjamin Crump, an attorney representing Floyd's family, said following the news. "The system needed to be listening to George Floyd."
