According to the Daily Mail, the father of Tyler Robinson, accused of the murder of Charlie Kirk, Matt Robinson, served in the police for 27 years. He saw a photo of his son on TV as a suspect, after which Taylor confessed to his guilt.
Matt Robinson demanded that his son be handed over to the police. For this, he called for help from a clergyman he knew, who contacted the investigating authorities. That's how Taylor ended up in the hands of law enforcement.
