A Capitol Police officer who suffered injuries during Wednesday's riot on Capitol Hill died on Thursday, CNN reported. Brian D. Sicknick died around 9:30 p.m. ET Thursday "due to injuries sustained while on-duty," prompting prosecutors to open a federal murder investigation, Capitol Police officials said.

"Officer Sicknick was responding to the riots on Wednesday, Jan. 6, 2021, at the U.S. Capitol and was injured while physically engaging with protesters," police stated. "He returned to his division office and collapsed. He was taken to a local hospital where he succumbed to his injuries."
