US television presenter Savannah Guthrie and her family have appealed to the public to continue to help search for their missing mother, who police believe was abducted seven weeks ago. We desperately ask this community for renewed attention to our mom's case, the Guthrie family said in a new statement shared with NBC Tucson affiliate KVOA for a special report on the case. Authorities have been searching for Guthrie's 84-year-old mother Nancy Guthrie since she was reported missing from her Tucson, Arizona on 1 February. Footage previously released from outside Nancy Guthrie's home revealed a masked figure, but nearly two months later, police still do not have a suspect. In their statement to KVOA released on Saturday, the Guthrie family thanked the community of Tucson for its support in the ongoing search for Nancy Guthrie, and included a renewed request for information. We continue to believe it is Tucsonans, and the greater southern Arizona community, that hold the key to finding resolution in this case, the family said. Someone knows something. They also urged the public to consult camera footage, journal notes, text messages, or conversations that might hold significance, stating that no detail is too small. We miss our mom with every breath and we cannot be in peace until she is home, they shared. Since their mother's disappearance, Savannah Guthrie and her siblings have posted multiple videos on social media and offered a $1 million reward for leads toward her return, in addition to the $100,000 reward from the FBI. A nationwide search has unveiled clues, including DNA evidence and alleged ransom notes, but no suspect has been identified. Pima County Sheriff Chris Nanos has said they believe Nancy was specifically targeted but are still investigating the circumstances of her abduction. Police have requested surveillance footage from neighbors from the night Nancy went missing as well as previous dates leading up to her disappearance.}
