南希·格思里失踪已达45天，而案件的最新进展对当局几乎毫无帮助。一位专家告诉CBS新闻，时间的延长意味着调查“变得难度大幅增加”。
执法部门消息人士向CBS新闻透露，过去几周已从安装在格思里图森住宅的监控摄像头中获取了更多图像。据信，她于2月1日凌晨在该住宅内被绑架。
这些图像来自固定在围栏上的摄像头，拍摄了住宅后部，另一台则显示了车道和车库门前方。图像中捕捉到了数周前（绑架事件发生前）的家庭成员、园艺工人和泳池工人。这些画面均未发现可疑情况，也没有任何图像显示前门摄像头中出现嫌疑人。
在对这位84岁女性（《今日》节目主持人萨凡纳·格思里的母亲）失踪案展开调查的第七周，联邦调查局2月10日分享的门铃摄像头视频仍是唯一已知的嫌疑人图像。
美国联邦调查局退休主管特别探员兰斯·莱辛告诉CBS新闻，这一切都表明“缺乏有意义的线索。这是我首先注意到的问题。”
他补充道：“维持调查、保持其时效性并争取新线索变得更加困难。”
现场发现的DNA仍在分析中，调查人员正借助法医基因谱系学技术希望突破案件。这项技术过去曾用于追查其他高调案件的罪犯，包括2022年杀害四名爱达荷大学学生的布赖恩·科伯格。
不过，莱辛警告称，这一过程“需要一段时间”。
“可能你在同一个DNA家族中会有多名潜在嫌疑人，必须分别独立调查每一个人。”他表示。
当局仍在收到线索，格思里家族宣布提供100万美元悬赏后，联邦调查局已收到超过1500条潜在线索。但自格思里家族最后一次呼吁公众协助以来已近三周，执法部门上一次召开新闻发布会讨论此案也已过去一个多月。
“我希望——我确信家属也极为希望——这种沉默是因为他们已掌握了线索，”莱辛说，“他们只需要更深入地调查。”

With few new leads 45 days after Nancy Guthrie’s disappearance, investigation “becomes much harder,” expert says

Nancy Guthrie has been missing for 45 days, and with the latest update in the case being of little use to authorities, one expert tells CBS News the extended timeline means it “becomes much harder to keep the investigation going.”
Law enforcement sources told CBS News that additional images were obtained in the last couple of weeks from surveillance cameras installed at Guthrie’s Tucson home, where she is believed to have been abducted from in the middle of the night on Feb. 1.
The images, taken from a camera fastened to a fence and focused on the back of the house and another that showed the driveway and front of the garage door, captured family members, landscapers and pool workers stretching back weeks prior to the kidnapping. Nothing was deemed suspicious, and no images reviewed showed the suspect captured on the front door camera.
In the seventh week of the investigation into the disappearance of the 84-year-old mother of “Today” co-host Savannah Guthrie, doorbell camera video shared by the FBI on Feb. 10 remains the only known images of the suspect.
Lance Leising, a retired FBI supervisory special agent, told CBS News it all points to “a lack of meaningful leads. That’s the initial thing it says to me.”
“It becomes much harder to keep the investigation going, keep it current and fight for new leads,” he added.
DNA recovered from the scene is still being analyzed, with investigators turning to forensic genetic genealogy in hopes of breaking the case open. It’s a technique that’s been used in the past to find other high-profile criminals, including Bryan Kohberger, the man who killed four University of Idaho students in 2022.
Leising warned, however, that the process “takes a while.”
“Maybe you’ve got multiple people within the same DNA family that could potentially be suspects. You have to investigate each one of those independently,” he said.
Authorities also continue to receive tips, with over 1,500 potential leads coming into the FBI after the Guthrie family announced a $1 million reward. But it’s been nearly three weeks since the family last called on the public for help and more than a month since law enforcement held a news conference to discuss the case.
“I’d like to be hopeful that — and I’m sure the family is incredibly hopeful — that the silence is because they’re on to something,” Leising said. “They just need to investigate harder.”
