Crime Scene Expert Calls Nancy Guthrie Kidnapping Probe ‘Botched’ as Man Pleads Guilty to Ransom Hoax

TUCSON, Ariz. — A prominent crime scene investigator has publicly criticized the handling of the investigation into the disappearance of Nancy Guthrie, the 84-year-old mother of “Today” show co-anchor Savannah Guthrie, calling the probe “so botched” due to what she describes as a lack of communication and unity between the victim’s family and law enforcement agencies involved in the case.
Crime scene expert Sheryl McCollum said the investigation has suffered from a disconnect between the Guthrie family and the law enforcement agencies leading the case, noting that Savannah Guthrie and her relatives have never appeared jointly with the FBI and the Pima County Sheriff’s Department to deliver a unified public statement. McCollum’s comments add to a growing chorus of criticism directed at the investigation, which has now stretched more than five months without a named suspect or an arrest.
Nancy Guthrie was last seen alive around 9:45 p.m. on January 31, when a family member dropped her off at her Tucson home following a family dinner. She was reported missing the following day, and investigators later discovered blood near the front doorstep of her residence, along with personal effects left inside the house, details that led authorities to treat the case as a kidnapping from early in the investigation.
Pima County Sheriff Chris Nanos, the lead official overseeing the local response to the case, has pushed back against suggestions that law enforcement is dismissing important leads or operating without coordination between agencies. Nanos has said that every piece of communication related to the case is being handled with significant care, and Savannah Guthrie has separately issued a statement expressing gratitude to both the FBI’s Phoenix field office and the Pima County Sheriff’s Office for what she described as their “tireless work” to help bring her mother home.
Even so, Nanos himself has become a focal point of public criticism as the case has dragged on. Questions have circulated for months over whether the investigation was mishandled from its earliest stages, with some observers pointing to Nanos’ decision to release the crime scene relatively quickly after Guthrie’s disappearance and to his limited direct experience with homicide and ransom investigations prior to taking on this case. Backlash intensified further after revelations emerged regarding Nanos’ professional history, including his 1982 resignation from the El Paso Police Department in Texas, which reportedly came amid a dispute with a supervisor over vehicle towing procedures. Nanos’ attorney responded to renewed scrutiny over that history with a lengthy written statement to the Pima County Board of Supervisors, stating that Nanos was never formally suspended during his subsequent four decades of service with the Pima County Sheriff’s Department, though he acknowledged Nanos had been suspended more than 40 years earlier while employed in El Paso. The statement also addressed confusion during a deposition in which Nanos reportedly did not understand a question related to discipline at a separate agency not governed by Arizona’s Peace Officers’ Bill of Rights.
Public reaction to the revelations about Nanos’ history has been largely critical, with social media users expressing frustration over the sheriff’s continued role leading the investigation. Commentary circulating online has included characterizations describing the case as mishandled from the outset, reflecting a broader pattern of public skepticism toward the pace and transparency of the investigation as it has unfolded over recent months.
Alongside the criticism of the investigation’s leadership, the case has also produced its first criminal conviction tied to the flood of ransom communications the Guthrie family has received since Nancy’s disappearance. In early July, a California man, Derrick Callella, 42, pleaded guilty in federal court to two felony charges, including transmitting a ransom demand across state lines and using a telecommunications device to threaten or harass, in connection with a false ransom message sent to the family. Prosecutors said Callella tested positive for drugs at the time of his court appearance, and he is scheduled to be sentenced on September 10, facing a term of five years of probation under the terms of his plea agreement.
The FBI has confirmed receiving several ransom notes over the course of the investigation, acknowledging that while some have been determined to be illegitimate extortion attempts unrelated to Guthrie’s actual disappearance, others remain under active investigation as potentially genuine communications from those responsible for her abduction. That distinction has added complexity to an already difficult case, as investigators work to separate credible leads from opportunistic hoaxes like the one that led to Callella’s guilty plea.
According to McCollum, the investigation’s forward path continues to focus on several key areas, including efforts to trace the digital origins of ransom letters that have not been publicly released, monitoring tips submitted by the public, and coordinating searches that may extend across state or national borders. She has also pointed to what she described as inexperienced leadership and significant forensic processing backlogs as ongoing obstacles slowing the investigation’s progress, in addition to the continued absence of any named suspect more than five months into the case.
Despite the mounting criticism directed at the pace and management of the investigation, both the Guthrie family and local law enforcement officials have continued to publicly emphasize their appreciation for the resources devoted to the case. A combined reward of $1.1 million remains available for information leading to Nancy Guthrie’s safe return, and authorities continue to urge anyone with relevant information to come forward through the Pima County Sheriff’s Department’s tip line or the FBI’s national tip line.
As of this report, no suspect has been publicly identified in connection with Guthrie’s disappearance, and investigators have not disclosed a timeline for when DNA evidence recovered from the scene, including a hair sample previously referenced in the investigation, might yield further leads. The case remains active, with the FBI and Pima County Sheriff’s Department continuing to coordinate their response even as public scrutiny over the handling of the investigation shows no signs of easing.

Thai Baht Hits 15-Month Low as Oil Prices and Dovish BoT Weigh on THB
OCBC analysts report the Thai Baht is near a 15-month low against the USD, pressured by rising oil prices, a stronger dollar, and higher US yields. The Bank of Thailand’s accommodative stance offers little support, though sharper depreciation could challenge policymakers if inflation concerns intensify.
Baht Under Pressure from Global Headwinds
The Thai Baht (THB) is trading near its weakest level in over 15 months against the US Dollar, as a confluence of external pressures continues to erode its value. According to OCBC’s Sim Moh Siong and Christopher Wong, the currency’s decline has been driven by a renewed spike in oil prices, compounded by a firmer USD and rising US Treasury yields. Thailand’s heavy reliance on imported energy makes it especially vulnerable to these global cost pressures, which in turn have stoked concerns about imported inflation. This dynamic has reinforced market expectations that US interest rates may remain elevated for longer, further diminishing the Baht’s relative appeal and sustaining depreciation pressure across the currency pair.
Bank of Thailand’s Accommodative Policy Adds to the Drag
Beyond external forces, the Bank of Thailand’s (BoT) monetary policy stance has also weighed on the currency. The central bank has maintained a notably accommodative posture, offering little support to counteract the Baht’s slide. Governor Vitai has publicly signaled no urgency to tighten policy, suggesting that authorities remain comfortable allowing gradual currency softness rather than intervening aggressively. This tolerance for gradual depreciation reflects a broader policy philosophy prioritizing growth and financial conditions over near-term currency stability. However, this passive approach means the THB currently lacks a domestic monetary policy buffer against the ongoing external shocks stemming from oil markets and shifting US rate expectations, leaving it more exposed to further weakening.
Risks of a Sharper Depreciation
Despite the BoT’s current tolerance for gradual THB softness, analysts caution that this stance could be tested if conditions worsen. Should oil prices remain elevated and imported inflation continue to build, the resulting economic strain may force policymakers to reconsider their passive approach. A sharper, more disorderly depreciation — rather than the current gradual slide — would likely raise concerns about financial stability and inflationary spillovers, potentially prompting the BoT to intervene or adjust its policy tone. In essence, while the central bank currently views Baht weakness as manageable, the combination of energy shocks and firm US monetary conditions represents a critical threshold that could compel a shift in Thailand’s policy calculus should pressures intensify further.

MOFSL stays bullish on Sun Pharma; sees 16% upside on innovation pipeline
Expanding specialty and innovative medicines portfolio, semaglutide launches across India and international markets, and the proposed Organon acquisition are major growth drivers in the medium term for the country’s largest pharma company by revenue and market cap. Despite pressure in the US generics segment, it has maintained the FY27 guidance of high single-digit revenue growth on account of continued traction in specialty products such as Leqselvi and Unloxcyt and strong momentum in the domestic business.

The short-term growth narrative is shifting away from traditional generics and toward specialty and innovative products. While the US formulations business declined 9.7% due to lower contribution from generic Revlimid and increased competition in some products, the company’s innovative medicines portfolio continued to gain traction across the US and international markets. The innovative portfolio will likely remain a key growth engine supported by products such as Ilumya, Odomzo and Cequa, along with the ramp-up of new launches. Motilal Oswal Financial Services (MOFSL) expects the specialty portfolio to deliver a 13% annual growth over FY26-FY28, aided by improving physician adoption and expanding market access.
AgenciesAnother potential growth lever is semaglutide. Beyond India, the company has secured approvals for generic semaglutide injections for Type-2 diabetes in South Africa and Brazil. The commercialisation is underway in South Africa while the Brazil launch is expected soon through a partner.
The medium-term outlook is led by a healthy innovation pipeline. Key milestones over the next 12-18 months include a USFDA decision on Ilumya for psoriatic arthritis in October 2026, topline phase-II data for GL0034 in Type-2 diabetes during the second half of 2027, progress on Fibromun, and regulatory filings for dermatology and oncology assets. The Organon acquisition is expected to complete by March 2027 quarter, which could expand Sun Pharma‘s global scale and product portfolio.
MOFSL has retained a ‘buy’ rating on the stock with a target price of ₹2,310, implying a 16% upside to Friday’s closing price of ₹1,989.4.The broking firm believes Sun Pharma remains on track for strong growth, supported by expansion in innovative medicines through partnerships, launches and wider reach.

New F&O closing auction rules: Impact on traders, investors decoded
What are exchanges changing?
Exchanges are changing the way the official closing prices of certain stocks are decided. The daily closing price is one of the most important numbers for market participants. It is used to calculate index closing levels, mutual fund portfolios, and settle derivatives contracts.
At present, a stock’s closing price is based on the average price of trades done in the last 30 minutes, between 3 PM and 3:30 PM.
From August 3, stocks that are available in the futures and options segment will have a separate closing auction. Their final closing price will be decided through this auction, instead of using the average price over last 30 minutes.
AgenciesTill now a stock’s closing price was based on average price of trades done in last 30 mins
How will the new closing auction work?
For stocks part of the F&O segment, normal trading will end at 3:15, after which the closing auction will begin. During this session, buy and sell orders are collected instead of being executed immediately. The exchanges will then calculate a single price at which the maximum number of buy and sell orders can be matched. That price becomes the stock’s official closing price.
To prevent sharp price swings, the auction price can generally move only within 3% above or below the stock’s average traded price between 3 and 3:15.

Investors can place both market and limit orders until 3:25. After that, only fresh limit orders are accepted, while market orders already entered cannot be changed or cancelled. These restrictions are meant to discourage last-minute changes or large market orders that could influence the closing price. Also, the auction will close at a random time between 3:28 and 3:30, making it harder for traders to time their orders at the last second.
What’s the big deal about last-minute order changes? Why should it matter?
One reason for the change is that there have been complaints about large orders being placed at the close of trading in a bid to influence the final price. Think of it as the final over of a cricket match. A few big shots in the last moments can alter the final score. Similarly, a few large trades just before the market closes can influence the closing price.
A closing auction helps find one common price at which the maximum quantity can be traded. This is expected to make the closing price more reliable and reduce the impact of sudden orders placed near the end of the session.
Another key reason for the change is to help mutual funds, especially passive funds, execute all their buy and sell orders in the closing auction. This will help them transact at or very close to the official closing price. Currently, asset managers place orders between 3 PM and 3:30 PM at different prices depending on available liquidity, which can lead to tracking errors. Brokerage Zerodha said the new rule helps improve the efficiency of the execution of large orders.
Then, what’s the relevance of the period between 3:30 and 3:40?
By around 3:35, the closing auction for stocks that have F&O contracts will be over. However, F&O contracts continue trading until 3:40. This gives F&O traders a few extra minutes to react to the stock’s final closing price before derivatives trading ends.
Does this mean the market will now close at 3:40?
No. For most stocks, trading will continue to end at 3:30. For stocks that have futures and options (F&O) contracts, normal cash-market trading will end at 3:15, after which a closing auction will determine the final closing price. Only the futures and options market will continue trading until 3:40.
Who will be impacted by the new rules? Do traders need to do anything differently?
The biggest impact will be on active traders, proprietary desks and other institutions that trade near the market close. Brokers could advance intraday square-off timings, so traders should check the revised cut-off times. Investors in non-F&O stocks are unlikely to notice much difference.
