The FBI has released video footage of the person suspected to have planted pipe bombs at the headquarters of the DNC and RNC the night before the Jan. 6 Capitol riots. The identity and motives of the bomber have remained unknown, and both devices were found and disposed of without injury.

The FBI is offering a $100,000 reward for information that leads to the arrest and conviction of the suspect. The suspect was masked and wore nondescript clothing aside from distinctive Nike Air Max Speed Turf shoes, black and grey with a yellow logo.

The bombs were “1x8-inch threaded galvanized pipes, a kitchen timer, and homemade black powder.” The FBI says the suspect placed the bombs between 7:30 and 8:30.

“These pipe bombs were viable devices that could have been detonated, resulting in serious injury or death,” Steven M. D’Antuono, FBI Washington Field Office Assistant Director in Charge, said in a public statement.

He added, “We need the public’s help to identify the individual responsible for placing these pipe bombs to ensure they will not harm themselves or anyone else.”

Pictures of the suspect were released quickly, but with the perpetrator still at large two months later, the FBI has released more evidence in the hope of public assistance.
