Matthew Coleman, 45, expressed optimism to a friend before perpetrating a horrific act. Despite appearing content with his family life, privately, he had become entangled in disproven conspiracy theories and delusions. Unexpectedly, he took his two children and fled to Mexico, leaving his wife behind, sparking a frantic search.
Abby reported the children missing when they failed to return home, confident that they were safe with Matthew. However, authorities tracked him to Mexico using a phone app, where he committed a heinous crime. He brutally murdered his 10-month-old daughter and two-year-old son with a spearfishing gun before disposing of the evidence.
Upon his return to the US, Coleman was arrested and confessed to the crime, citing beliefs in a debunked conspiracy theory. His wife acknowledged their shared interest in the theory but noted his escalating paranoia. Coleman, deemed unfit for trial, has exhibited concerning behavior in custody.
