Callella’s federal filing documents the contact. It does not document the information he wanted.On February 4, 2026, Derrick Callella sent text messages to A.G. and T.C. — Nancy Guthrie’s daughter and son-in-law — from a VoIP number. The message asked about a bitcoin transaction. About three minutes later, a nine-second call was placed to a family member.In the factual basis, Callella admitted he sent the texts to see if the family would respond. The same filing says he intended to harass them by seeking information about the investigation into N.G.’s disappearance.This Interview Room segment stays inside that paper. We read the government’s own sentence.If it isn’t in the document, it isn’t in this episode.Re-upload from 9/10/2026
