The FBI released new videos Tuesday that investigators said show the person suspected of planting two pipe bombs the night before the January riot at the Capitol.
"These pipe bombs were viable devices that could have been detonated, resulting in injury or death.
The FBI said the bombs were planted between 7:30 p.m. and 8:30 p.m.
The FBI said the person also wore distinctive footwear — Nike Air Max Speed Turf shoes with black, gray and yellow details.
The devices' discovery pulled dozens of police away from their usual posts about 90 minutes before rioters stormed the Capitol.
Steven Sund, the former chief of the Capitol Police, has said he believes the bombs were planted as a diversion.
In releasing the video, the FBI said agents hope someone may recognize the person's gait, body language or other mannerisms. »
