Dad Accused of Murdering His Kids with Speargun for Having 'Serpent DNA'

Matthew Coleman, a Santa Barbara surf instructor with QAnon beliefs, allegedly kidnapped both of his young children and crossed the border with them into Mexico. He’s accused of killing the 2-year-old and 10-month-old with a gun used for spearfishing, because he feared they had "serpent DNA." As he faces federal charges, Coleman has reportedly started to self-harm while behind bars. Law&Crime’s Sierra Gillespie spoke with retired NYPD detective Tom Smith about the bizarre and brutal case.
