Investigators had struggled for weeks to build a federal murder case in Sicknick’s death as they pored over video and photographs to try to determine the moment in which he suffered his fatal injuries. Investigators determined that initial reports suggesting Sicknick had been struck with a fire extinguisher weren’t true.
The two men are charged with nine counts, with several of them relating to violence and assaulting officers.
Court records show federal authorities also searched Tanios’ property in West Virginia this weekend.
Prosecutors are seeking to keep him in jail pending trial, because he could flee or obstruct justice, and because they believe he is a danger to the community, court records say.
A native of New Jersey, Sicknick joined the Capitol Police in July 2008 and had served in the Department’s First Responder’s Unit. He also served as a staff sergeant for the New Jersey National Guard.
