San Fernando Valley Man Found Guilty in Terror Plot to Bomb a Rally in Long Beach
LOS ANGELES – A federal jury this afternoon convicted a San Fernando Valley man for attempting to bomb a rally in Long Beach for the purpose of causing mass casualties.
Mark Steven Domingo, 28, of Reseda, was found guilty of providing material support to terrorism and attempting to use of a weapon of mass destruction.
As a result of today’s guilty verdicts, Domingo faces a statutory maximum sentence of life in federal prison. Domingo, who has been in federal custody since his arrest in April 2019, is scheduled to be sentenced by United States District Judge Stephen V. Wilson on November 1.
The investigation into Domingo was prompted by his online posts and conversations in an online forum in which he expressed support for violent jihad, a desire to seek retribution for attacks against Muslims, and a willingness to become a martyr. After considering various attacks – including targeting Jewish people, churches, and police officers – Domingo decided to bomb a rally scheduled to take place in Long Beach in April 2019.
As part of the plot, Domingo asked a confederate – who actually was working with the FBI as part of the investigation – to invite a bomb-maker into the scheme. Domingo then purchased and provided to the confederate and the bomb-maker – who in fact was an undercover law enforcement officer – several hundred 3½-inch nails to be used as shrapnel for the bombs. Domingo specifically chose those nails because they were long enough to penetrate organs in the human body.
Leading up to the attack, Domingo called for another event similar to the October 2017 mass shooting in Las Vegas. Following an attack on Muslims in New Zealand in March 2019, Domingo called for retribution in an online post.
Domingo selected the Long Beach rally as his target and, in April 2019, drove his confederate and the undercover officer to Long Beach to scout the location he planned to attack. While there, Domingo discussed finding the most crowded areas so he could kill the most people. On April 26, 2019, Domingo received what he thought were two live bombs, but were actually inert explosive devices delivered by an undercover law enforcement officer. He was arrested that same day with one of the bombs in his hands.
This matter is the product of an investigation by the FBI’s Joint Terrorism Task Force. JTTF members who participated in the investigation include the FBI, the Los Angeles Police Department, the Naval Criminal Investigative Service, the Los Angeles County Sheriff's Department, and the Long Beach Police Department.
This case is being prosecuted by Assistant United States Attorneys Reema M. El-Amamy and David T. Ryan of the Terrorism and Export Crimes Section, and Trial Attorneys Lauren Goddard and Joshua Champagne of the Department of Justice’s Counterterrorism Section.
