Authorities investigating the disappearance of 84-year-old Nancy Guthrie have announced the arrest of a California man accused of sending disturbing messages to her family. According to court records, Derrick Callella allegedly contacted relatives shortly after public appeals for help were shared, referencing cryptocurrency payments in texts that heightened anxiety during an already difficult time. Investigators later concluded that the communications were not connected to Nancy’s disappearance, but officials say the timing created significant emotional strain for her loved ones. Once the messages were reported, law enforcement traced the number and moved quickly to identify the sender.
Prosecutors state that the suspect also placed a short phone call to another family member, adding to concerns about the nature of the outreach. When questioned, court documents indicate he acknowledged closely following media coverage of the case and claimed he obtained contact details online before sending the messages. Authorities allege the purpose was to provoke a response rather than issue a legitimate ransom demand. He now faces federal charges tied to transmitting communications that falsely suggest ransom activity. Officials have underscored that the alleged actions appear unrelated to other investigative leads but illustrate how hoaxes can complicate sensitive cases.
Meanwhile, the investigation into Nancy Guthrie’s disappearance remains active in Arizona. Officials have noted that evidence discovered at her residence led them to treat the matter as a criminal investigation rather than a routine missing-person search. Reports indicate that key personal items—including her phone and vehicle—were left behind, and authorities believe she did not depart willingly due to health considerations. Investigators continue reviewing surveillance footage, analyzing forensic material, and following community tips while urging the public to avoid speculation that could interfere with progress.
Nancy’s children have issued heartfelt requests for empathy and responsible sharing of information as the search continues. They describe their mother as a compassionate presence whose absence has deeply affected their family. Law enforcement representatives reaffirm that locating her remains the top priority and encourage anyone with credible details to come forward. In cases like this, accurate information and public cooperation play a vital role—helping investigators move forward while offering families the support they need during uncertain times.
