Federal grand jury indicts man accused in Long Beach terror plot

A federal grand jury indicted a Reseda man for his role in plotting to bomb a rally in Long Beach in late April, the Department of Justice announced today.

The indictment formally charges Mark Steven Domingo, a 26-year-old former Army infantryman, with providing material support to terrorists and attempted use of a weapon of mass destruction.

If convicted, Domingo faces a maximum sentence of life in federal prison.


Federal officials say Domingo expressed support of violent jihad and wanted retribution for the attacks on Muslims in New Zealand.

He planned to bomb a white supremacist rally in Bluff Park that was eventually cancelled after a counter-rally was planned, officials said.

Domingo asked his confidant, who was actually an undercover FBI source, to find him a bomb-maker, officials said. He then bought hundreds of 3-inch nails to be used as shrapnel for the bombs, they said.

The confidant and the “bomb-maker,” who was an undercover agent, delivered an inert bomb to Domingo to be used in the plot on April 26, according to authorities. The complaint says Domingo drove his confidant and the bomb-maker to Long Beach to scout Bluff Park for the attack.

“Domingo said they should try to find the most ‘crowded’ areas in order to kill the most people in the attack,” an affidavit says. He was arrested shortly after and the rally went on as scheduled, according to federal officials.

Domingo has been in custody without bail since his arrest.
