Matthew Coleman, a 45-year-old man, expressed optimism about the future just before he engaged in a horrific act. Despite appearing content with his family life, he had delved into false conspiracy theories and developed delusions.
Unexpectedly, Matthew took his two young children, Kaleo and Roxy, on a trip to Mexico, leaving his wife behind while they were preparing for a family camping trip. Concerned, Abby reported the children missing when they did not return home as planned.
Despite Abby’s belief that the children were safe, authorities found out that Matthew had taken them to Mexico. Tragically, on August 10, he brutally murdered his children with a spearfishing gun, hiding their bodies in a wooded area.
After committing the heinous act, Matthew disposed of evidence, including his blood-stained clothes and his daughter’s belongings. A local ranchhand discovered the children’s remains shortly after the crime, leading to Matthew’s arrest upon his return to California.
During police interrogation, Matthew confessed to killing his children, attributing his actions to his belief in a debunked conspiracy theory. He claimed that he needed to eliminate his children to protect the world from what he perceived as a threat.
Currently, Matthew is deemed unfit for trial, exhibiting self-harming behavior in prison and struggling to communicate effectively. Abby, his wife, acknowledged researching the same conspiracy theories but noted her husband’s increasing paranoia.
Matthew remains in protective custody, isolated from other inmates due to his behavior. His case raises concerns about the influence of misinformation and the tragic consequences it can lead to.
