The family of the Boulder, Colorado firebombing suspect is in federal custody, sources confirm to Fox News.

According to senior sources within the Department of Homeland Security (DHS) and Immigration and Customs Enforcement (ICE), the wife and five children of 45-year-old Mohamed Sabry Soliman were taken into custody. 

The family is being processed for expedited removal, sources said.

Soliman is an Egyptian national who overstayed his visa after entering the U.S. during the Biden administration, three DHS and ICE sources told Fox News.

Soliman first arrived in the U.S. after landing at Los Angeles International Airport on Aug. 27, 2022, with a non-immigrant visa. 

He was authorized to stay through Feb. 2, 2023, but never left. On Sept. 9, 2022, he filed a claim with U.S. Citizenship and Immigration Services. 

On March 29, 2023, Soliman was granted work authorization, which was valid through March of this year.

Victims and witnesses observed Soliman throw what appeared to be a glass bottle, which burst upon impact, creating large flames, towards a crowd of peaceful pro-Israel demonstrators in Boulder on Sunday, June 1, authorities said.

Twelve individuals were injured in the attack. None of the victims have died.

Now facing a litany of charges – including multiple counts of attempted first-degree murder, first-degree assault, and possession of incendiary devices – Soliman is being held on a $10 million bond.

Judicial District Attorney Michael Dougherty outlined the severe potential penalties facing Soliman if convicted on all charges related to the June 1 attack. He faces 16 counts of attempted first-degree murder – eight for attempted murder with intent and deliberation, and eight for attempted murder with extreme indifference.

If convicted and the sentences are ordered to run consecutively, he could face a maximum of 384 years in state prison for those charges alone. In addition, Soliman is charged with two counts of use of an incendiary device, which could add up to 48 years if served consecutively.

He also faces 16 counts of attempted use of an incendiary device, carrying a potential additional 192 years. In total, the maximum possible sentence could reach 624 years if all convictions are handed down and run consecutively.

Along with charges on the state level, he has also been federally charged with a hate crime involving actual or perceived race, religion or national origin. 

His next court appearance, for filing charges, will be Thursday, June 5 at 3:30 p.m. MT.
