Three former Minneapolis police officers were criminally charged Wednesday in connection with the death of George Floyd in their custody, according to court records. 

In addition, Derek Chauvin, a fourth former officer who had already been charged with third-degree murder in the case, will now be charged with second-degree murder, the records show, in addition to the previous charge. 

The ex-cops, Tou Thao, J. Alexander Kueng and Thomas Lane, had assisted Chauvin in arresting Floyd on Memorial Day on the suspicion that Floyd passed a counterfeit bill. They were charged with aiding and abetting murder.

Second-degree murder and aiding and abetting second-degree murder are punishable by up to 40 years in prison. Manslaughter and aiding and abetting manslaughter are punishable by up to 10 years in prison.
