Song, whom prosecutors described as the leader of the cell, received the longest sentence.
He was sentenced to 100 years in federal prison after being convicted of attempted murder of a law enforcement officer, discharging a firearm during a crime of violence and several terrorism-related offenses.
The remaining defendants also received lengthy prison terms.
Maricela Rueda was sentenced to 70 years.
Cameron Arnold, Savanna Batten, Zachary Evetts, Bradford Morris and Elizabeth Soto each received 50-year prison sentences.
Daniel Rolando Sanchez-Estrada was sentenced to 30 years.
Together, the eight defendants received a combined sentence of 450 years behind bars.
Acting Attorney General Todd Blanche said the sentences send a clear message.
“The sentences handed down today make clear that Antifa terrorists who attack law enforcement and federal facilities will face swift and uncompromising justice,” Blanche said.
“Their violent extremism has no place in our country, and the Department of Justice will continue to aggressively investigate, disrupt, and prosecute those who threaten law enforcement officers or undermine the rule of law.”
FBI Director Kash Patel said investigators will continue targeting violent extremist networks.
“Today’s sentencings show the FBI remains committed to identifying, locating, and dismantling Antifa and its funding networks across the country,” Patel said.
“Acts of violence against our law enforcement partners will not be tolerated, and we continue our work to protect communities across the country from domestic terrorism.”
U.S. Attorney Ryan Raybould said the attack went far beyond lawful protest.
“Their terrorist acts, attempted murder, vandalism, and explosives launched at a detention facility were a far cry from a peaceful protest or First Amendment expression,” Raybould said.
