"There are no words to describe the profound grief that envelops an entire community when a child is murdered," Acting U.S. Attorney Randy Grossman wrote in a press release. "The Department of Justice is determined to achieve justice for these victims and their loved ones."
Coleman is expected to make his first court appearance on the indictment on Thursday in United States District Court in Los Angeles, according to authorities. He will appear in United States District Court in San Diego, where the case will be prosecuted, at a date that has not yet been determined
He was enlightened by QAnon to kill his 10-month-old daughter and 2-year-old son with a spear fishing gun in Mexico was indicted by a San Diego federal grand jury Wednesday.
Matthew Taylor Coleman, 40, is charged with two counts of foreign first-degree murder of United States nationals, according to a statement from the U.S. Attorney’s Office for the Southern District of California.
Coleman, a surfing instructor from Santa Barbara, could face the death penalty.
"By law, the charges are eligible for the death penalty," officials said in the statement. "The Attorney General will decide whether to seek the death penalty at a later date."
A criminal complaint filed last month accuses of killing his children "by shooting a spear fishing gun into their chests."
He confessed to killing the children, according to the complaint, telling investigators that "he believed his children were going to grow into monsters so he had to kill them."
"Coleman explained that he was enlightened by QAnon and Illuminati conspiracy theories and was receiving visions and signs" that revealed his wife was telling him "he was saving the world from monsters," the complaint said.
According to the document, Coleman said he knew it was wrong to kill his children, "but it was the only course of action that would save the world."
Coleman's wife called police Aug. 7 to report that her husband left with their two kids. The family was supposed to go camping together, but instead Coleman put the kids in their Mercedes-Benz Sprinter van and left. She said they hadn't argued prior and she had no reason to believe her husband would harm her children, but she was concerned because he hadn't taken a car seat.
The next day, she reported them missing and police helped her track Coleman using the "find my iPhone" app. His last known location was in Rosarito, Mexico.
On Aug. 9, still using the app, Coleman's wife's friends showed police that he was moving toward the U.S.-Mexico border. When authorities met him there, he did not have his children in the van.
