Law Enforcement kept quiet while the investigation was ongoing. It seems to me that the lag time between news of his death and the arrests helped to limit its currency in the news. His funeral and the honoring of him were very big local news. Hundreds made his funeral, thousands lined the miles as his remains were brought from his nearby hometown of Clyde to Abilene for the funeral.

Shocking story about the “ordinary” couple arrested in the murders. Parents with 3 kids, living in Abilene.
