NBC’s Today co-host Savannah Guthrie spoke publicly for the first time Wednesday about the January abduction of her mother, revealing new details and announcing that her family is offering a $1 million reward for information leading to her safe return.

Guthrie described the ongoing anguish for her family and appealed directly to the public for any tips. Authorities have not identified a suspect in the case, according to law enforcement sources.

The abduction occurred in January, but Guthrie had remained silent until now to allow investigators to pursue leads without media interference. She expressed hope that the reward and new information would help bring her mother home safely.

Federal and local authorities continue to investigate. Anyone with information is urged to contact the tip line established by the family.
