The D.C. medical examiner said autopsy results show that Capitol Police Officer Brian Sicknick suffered two strokes and died of natural causes the day after a violent riot broke out at Capitol Building in January.
At the time of the incident, it was reported that Sicknick "was struck with a fire extinguisher."
D.C. medical examiner Francisco J. Diaz said there was no evidence that Sicknick suffered an allergic reaction to chemical irritants. Julian Elie Khater, 32, and George Pierre Tanios, 39, were accused of spraying Sicknick with a chemical irritant and were later arrested for assaulting an officer.
"The USCP (United States Capitol Police) accepts the findings from the Office of the Medical Examiner, but this does not change the fact Officer Brian Sicknick died in the Line of Duty, courageously defending Congress and the Capitol," a statement given by the Capitol Police said. "The Department continues to mourn the loss of our beloved colleague. The attack on our officers, including Brian, was an attack on our democracy. Working with the U.S. Attorney's Office for the District of Columbia, the F.B.I.'s Washington Field Office and the Metropolitan Police Department, the USCP will continue to ensure those responsible for the assault against officers are held accountable."
