A new Brian Entin Investigates segment examines potential motives and health factors in the disappearance of Nancy Guthrie, missing for more than two months. On the Tuesday, April 7 episode, cold case specialist Brian Martin discussed the Nancy Guthrie disappearance with host Brian Entin. Martin suggested Savannah Guthrie’s mother may have been targeted for a monetary motive, while perpetrators possibly misjudged her health. Entin noted that if an unintended death occurred, it could constitute felony murder. Nancy Guthrie was reported missing on February 1; no suspects have been identified, and the family is offering up to $1 million for information.
