Dallas police Chief Renee Hall is resigning at the end of the year, the city manager says.

The city announced Tuesday that City Manager T.C. Broadnax accepted Hall’s resignation letter, which initially stated she would resign effective Nov. 10. However, Broadnax said he asked Hall to stay on until the end of 2020.

“This year has been tumultuous and uncertain. A few more months of her leadership are key for several projects and for a seamless transition within the police department,” Broadnax said in a statement. “In her three years of service, Chief Hall has provided consistent, passionate, resilient and robust leadership to our City. She has implemented a host of reforms that will assist our department as we move forward.”
