Ellison wrote a letter to Hennepin County Judge Peter Cahill on Wednesday asking him to modify his sentencing memorandum to “more accurately reflect the experiences of the four children who witnessed Mr. Floyd’s murder and subsequently testified at trial.” Floyd was killed in May 2020 after former Minneapolis police officer Derek Chauvin knelt on Floyd’s neck for nearly nine minutes. Chauvin has been convicted of murder and manslaughter, and was sentenced last month to 22.5 years in prison. ADVERTISEMENT Four girls witnessed Floyd’s killing. One of them, Darnella Frazier, has gained national praise for filming the now-viral video of Floyd’s death that sparked months of protests across the country.
