QAnon Surfer Dad Believed Killing His Kids Would 'Save The World,' FBI Says

Matthew Taylor Coleman “became significantly more paranoid that people around him were involved in a conspiracy,” weeks before the deaths of his 2-year-old son and 10-month-old daughter, according to new federal court records.

A Santa Barbara surf instructor who became entranced by a web of conspiracies and later allegedly killed his two young children in Mexico grew increasingly “paranoid” in the weeks leading up to the pair of slayings, newly filed court documents show. 

Matthew Taylor Coleman, a QAnon follower, believed that killing his children would “save the world” — according to an FBI search warrant petition filed on March 28 that Oxygen.com obtained — after becoming convinced his church group was engaged in a mass conspiracy against him. 

Coleman allegedly abducted and killed his 2-year-old son and 10-month-old daughter with a spear gun in Rosarito, Mexico on Aug. 9, 2021 after he’d become convinced his wife had passed “serpent DNA” onto his kids. He was later arrested at the U.S. border while trying to re-enter the country.

Federal agents filed the latest search warrant application in an attempt to gain access to two Instagram accounts Coleman used. The social media accounts in question include Coleman’s now-removed personal Instagram and a second account for the surf school he and his wife operated; the warrant requests access to over 400 direct messages Coleman sent to roughly 60 separate Instagram users.

The newly filed court records, however, also unveil investigators' insights into Coleman’s mindset in the days and weeks leading up to the murders of his son and daughter. According to his wife, Abby Coleman, she and her husband had become enmeshed in online research of QAnon conspiracies, which broadly posit that a shadowy cabal of Satan-worshiping cannibalistic pedophiles was conspiring against regular Americans and that former president Donald Trump was working to save them.

“A.C. explained that she and her husband were researching QAnon, and M. Coleman became significantly more paranoid that people around him were involved in a conspiracy,” the warrant application stated.

His spouse — referred to as "A.C." in court documents — said that, as Coleman dug deeper into the online conspiracy, he began to suspect that people close to him and those he knew were also plotting against him. 

“[She] said that M. Coleman started doing a lot of research on leaders running ‘the church’ and found that they may have been part of the conspiracy. A.C. explained that M. Coleman began seeing 'signs' in people’s social media posts, and M. Coleman believed he was able to connect the people running 'the church' to people in their community and to some of their best friends.”

Under questioning, Coleman also allegedly revealed his fixation on the secret meanings behind certain hand gestures or signals, which he said were symbolic of someone being “part of the conspiracy and showing their allegiance.”

In one instance, Abby Coleman, too, also texted her husband a cryptic Instagram meme that stated, “symbolism is the language of the satanic elite”

According to the FBI, while identifying his dead children using photographs of their bodies, Coleman also allegedly suggested to agents that his children’s deaths had been prophesied. 

“He knew what he did was wrong but it was the only course of action that would save the world,” the FBI warrant affidavit stated.

Last month, separate court documents revealed the California father’s supposed paranoid delusional belief that he was living in “The Matrix,” which seemingly manifested shortly before allegedly carrying out the double murder of his children. After crossing into Mexico, Coleman claimed he saw “all the pieces being decoded like 'The Matrix,' and that he was Neo," referring to the sci-fi blockbuster and the film’s primary protagonist played by actor Keanu Reeves. 

Coleman also allegedly spoke of time travel and teleportation during an interview with FBI agents last year.

A judge ordered him to undergo a psychiatric evaluation last August.

Coleman’s team of public defenders didn’t immediately respond to Oxygen.com’s requests for comment regarding the latest court filings on Friday.
