Authorities have released new details about a potential suspect in the disappearance of Nancy Guthrie – the mother of US TV host Savannah Guthrie -and have said they are doubling the reward for information.
The FBI also shared new identifying details about a possible suspect seen in images and video the bureau previously released showing a masked individual on the porch of the 84-year-old’s home in Tucson, Arizona, shortly before she went missing in the early hours of 1 February.
In a statement, FBI Phoenix described the person as “male, approximately 5ft 9in-5ft 10in tall, with an average build” and said he can be seen wearing “a black, 25-liter ‘Ozark Trail Hiker Pack’ backpack” in the footage shared by law enforcement.

The FBI also said it is increasing its reward up to $100,000 (£73,400) for information leading to the location of Ms Guthrie, who police believe was taken against her will.
The reward, which was previously up to $50,000 (£36,700), also applies to information that leads to the arrest and conviction of anyone involved in her disappearance.
Over 13,000 tips from the public have been received since 1 February, according to the FBI.

Speaking to reporters following his release, Carlos Palazuelos, who had been detained during a traffic stop, said he was innocent and did not know who Savannah Guthrie was.
Police said Nancy Guthrie has difficulty walking, has a pacemaker, and requires daily medication for a heart condition.
On Thursday, Savannah Guthrie, who co-hosts the Today show, posted on social media a home video montage of her mother with the caption: “Our lovely mom. We will never give up on her. Thank you for your prayers and hope”.
