A Texas forensic artist has released an unofficial sketch of a suspect in the disappearance of Nancy Guthrie, a 84-year-old woman who went missing from her Tucson home on February 1st. The FBI has expanded its search efforts into Texas with digital billboards and a $50,000 reward, as they seek information leading to her recovery. The artist, Lois Gibson, a retired Houston Police Department forensic artist, created the sketch based on surveillance images of a masked individual seen outside Guthrie's home. Gibson, a University of Texas alumna and Guinness world record holder for 'Most Successful Forensic Artist', has helped identify over 751 criminals. The FBI has posted digital billboards in Houston, Dallas, San Antonio, and El Paso featuring Nancy Guthrie's photo and an FBI tip line. Nancy Guthrie's daughter, Savannah Guthrie, a journalist and former attorney, has shared updates on her mother's disappearance on social media, expressing the family's determination to find her. Savannah has also released childhood videos and photos of her mother, emphasizing the family's unwavering commitment to finding Nancy.
