Matthew Taylor Coleman, a 40-year-old Santa Barbara surfing school instructor, has been charged with foreign murder of US nationals after allegedly taking his 2-year-old son and 10-month-old daughter into Mexico and killing them, according to an affidavit filed as part of a federal criminal complaint and a statement from the US Attorney’s Office for the Central District of California.
Stopped for questioning at the US-Mexico border, Coleman allegedly told investigators he shot the children with a spear fishing gun, then hid their bodies, the affidavit said.
Coleman was detained at the border and transported to a local jail by authorities.
CNN is working to determine whether Coleman has legal representation. He was scheduled for an initial court appearance Wednesday in US District Court in Los Angeles, the US Attorney’s Office said.
Mexican police found the bodies Monday
Police in Santa Barbara were initially alerted on Saturday by Coleman’s wife, who said he had taken the children, hadn’t told her their destination and wouldn’t respond to text messages, according to the affidavit. She told police she did not feel the lives of the children were in danger and asked for police to speak with Coleman, who did not respond to police calls.
The next day, according to the affidavit, Coleman’s wife and a police officer used the ‘Find My Phone’ application on her laptop to determine that Coleman’s phone had been last tracked in Rosarito, Mexico, just south of Tijuana in Baja California along the US-Mexico border.
Federal agencies were made aware to be on the watch for Coleman’s return, which occurred around 1 p.m. Monday, according to the affidavit. When the vehicle was stopped at the border, Coleman was the lone occupant, the affidavit said.
Mexican law enforcement was notified about the missing children and, according to the affidavit, police in Rosarito confirmed that two children matching the description of Coleman’s were found dead that morning.
During his interview with the FBI, Coleman said he had killed his children in Rosarito, the affidavit said.
He told authorities “he believed his children were going to grow into monsters so he had to kill them,” the affidavit said, speaking about QAnon conspiracy theories and the belief that his wife passed along “serpent DNA.”
Coleman said of the killings that “he knew it was wrong, but it was the only course of action that would save the world,” according to the affidavit.
The Illuminati is a conspiracy theory that a secret society controls the world, while “serpent DNA” is possibly a reference to a long-running theory that the world is secretly run by a cabal of reptilian humanoids.
