Benjamin Crump, an attorney for the Floyd family, told CNN Wednesday that he is confident the other officers will be charged before Thursday's public memorial in Minneapolis.

"I am confident that these officers will be charged before people in Minneapolis say their final goodbyes to George Floyd, may he rest in peace," he said.

In addition to possible charges against the other officers, Ellison could also choose to upgrade the third-degree murder charge against Chauvin, according to Don Lewis, the special prosecutor in the trial of the officer who fatally shot Philando Castile during a traffic stop.

Minnesota AG cautioned for patience

Ellison was appointed by Gov. Tim Walz to take over the case from Hennepin County Attorney Mike Freeman on Sunday.

A former Demoratic congressman, Ellison previously said that he had "every expectation" that charges will be filed against the officers and that he hoped they'd come soon. But on Monday, after taking over the case, he cautioned against a rush to judgment and said prosecutors will be careful and methodical in bringing charges.

"We are moving as expeditiously, quickly and effectively as we can," he said. "But I need to protect this prosecution. I am not going to create a situation where somebody can say this was a rush to judgement."
