The other three officers have pleaded not guilty and their lawyers said earlier this year that they were headed to trial Dec. 2.

In her guilty plea, Colletta admitted that she and fellow officers of the Civil Disobedience Team ran into Hall downtown during a Sept. 17, 2017, protest, two days after the acquittal of former St. Louis police Officer Jason Stockley on a murder charge. The other officers believed Hall was a protester, and officers tackled him as he was following Colletta’s orders and getting to his knees, her plea says.

Hall’s lawsuit said that he was following protesters who had damaged windows and flowerpots when officers began firing bean bag rounds at the crowd and using pepper spray, despite a lack of justification for the use of force. Hall also did not hear an order for the crowd to disperse before force was used.

When Colletta and other officers arrived, Hall had his hands up and was getting on the ground, as ordered, when he was picked up and slammed down twice, the suit says. He was then kicked and beaten with batons and fists. Officers searched his backpack and destroyed his camera and cellphone, the suit says.
