The FBI said it is targeting a single assailant as it continues to investigate the death of US Capitol Police Officer Brian Sicknick, who died of injuries sustained in the Jan.6 riot.
A federal police source and another close to the investigation confirmed the news on Saturday.
Sicknick, 42, was injured “while physically interacting with protesters” and returned to his division office, where he collapsed, according to a statement from Capitol Police. He was taken to hospital, where he later died on January 7.
Officers have not identified the exact cause of Sicknick’s injuries, but recently said they suspect it was due to a possible aerosol-type irritant, such as the bear spray he inhaled during the riot. The investigation into Sicknick’s death is being treated as an assault.
According to officials, a video shows a person attacking several officers, including Sicknick, with spray. The suspect is also heard discussing the alleged attack prior to the incident, authorities said.
Federal authorities have not identified the suspect and the FBI has yet to release the video.
Five people, including Sicknick, were killed after a crowd of supporters of then-President Donald Trump stormed the Capitol to prevent Congress from formally accepting the Electoral College votes that led to President Joe Biden’s November election.
