Check out 1:38 in. Look for fire extinguisher coming from the left side of the screen.

The FBI affidavit filed in the case of Robert Sanford, a retired firefighter arrested in connection with his alleged actions during the melee which the FBI stated included throwing a fire extinguisher into a crowd of Capitol police officers.

They do not mention Officer Brian Sicknick by name as the victim but here’s the relevant excerpt:

“The object appears to strike one officer, who was wearing a helmet, in the head. The object then ricochets and strikes another officer, who was not wearing a helmet, in the head. The object then ricochets a third time and strikes a third officer, wearing a helmet, in the head. Immediately after throwing the object, the Subject moves quickly in the opposite direction.”

There’s many charges listed including:

“Finally, there is probable cause to believe that SANFORD violated 18 U.S.C. 111(a)(1), which makes it a crime for anyone to forcibly assault, resist, oppose, impede, intimidate, or interfere with any United States law enforcement officer while that officer is engaged in the performance of their official duties.”
