Capitol Police officer's death remains mired in conflicting reports and official silence Caitlin Dickson More than a month after the insurrection at the Capitol, the circumstances surrounding the death of a U.S. Capitol Police officer who responded to the Jan. 6 attack are something of a mystery. Despite quickly becoming the subject of a federal investigation, the death of Brian Sicknick, a 42-year-old Capitol Police officer, has not led to any arrests, nor have autopsy results or other findings from the medical examiner been released. In fact, investigators have yet to provide the public with any official updates on the status of their probe since it was first announced, leaving journalists to rely on incomplete bits of information provided by anonymous law enforcement sources.
