FBI Special Agent Patrick Sanford completed his direct examination narrating wiretap calls and Magbanua's post-interview flight, then faced extended cross-examination in which defense counsel extracted concessions on the unrecorded Rivera proffer and a recorded inducement offer. The State formally rested after six days of testimony, and a Richardson issue arose over a defense witness whose account appeared to change mid-trial.
Full day summary
Day 6 was consumed almost entirely by the conclusion of FBI Special Agent Patrick Sanford's testimony, bookended by pre-session evidentiary rulings and a post-rest procedural dispute.
Before the jury was seated, Judge Wheeler admitted two phone recordings over defense hearsay objection. Defense counsel DeCoste argued that the government's undercover ruse did not transform other participants' statements into non-assertive acts. Wheeler overruled, admitting Exhibit 128 to show the existence of an additional contact and Exhibit 134 — Charlie Adelson's return call to the undercover — as a fact-of-communication exhibit to contextualize subsequent wire calls.
On direct examination, the prosecution narrated wiretap calls spanning April 20–29, 2016. Sanford testified that the Dolce Vita surveillance recording contains no mention of Dan Markel's name, the word "murder," or any background explanation of the Adelson family's exposure — framed against Magbanua's October 2019 sworn statement that she knew nothing of the murder until Garcia's arrest. He identified digits Magbanua relayed to Garcia in Call I as matching the last four of the undercover's phone number on the flyer handed to Donna Adelson. In Call W, Magbanua repeatedly told Charlie she had personally called the undercover number and found it non-operational; Sanford testified she never called the number and it was active and working. Charlie Adelson's direct call to the undercover on April 28 (Exhibit 134) was played, in which the undercover referenced "Katie and Duca" as people whose hired man had not been paid. That evening, Magbanua speculated on wire that "it could have been another Katie and another Tato." In Calls GG, Donna Adelson reassured Charlie he had "nothing, literally nothing to worry about," characterizing the FBI approach as someone fishing for money. Sanford closed the direct segment by describing Magbanua's post-interview conduct following the May 24, 2016 interview attempt: she acquired a burner phone, toggled her primary phone to defeat cell-tower tracking, vacated her residence permanently, and remained out of law enforcement reach for approximately five months until agents located her via intermittent cell-tower pings and arrested her outside a shopping center in October 2016.
On cross-examination, DeCoste targeted several evidentiary gaps. He established that the September 30, 2016 Rivera proffer — the first session in which Rivera named Magbanua — was neither recorded nor documented in a 302, and that Sanford had told defense counsel under oath at his 2019 deposition that DOJ policy required recording any inmate in any custody. Sanford acknowledged he was "mistaken" and had never corrected the record before trial. A court-read stipulation directly refuted Rivera's claimed sighting of Wendi Adelson with the Markel children the day before the murder: daycare records showed Dan Markel dropped the children off on both July 17 and 18, 2014, a discrepancy Sanford acknowledged. Defense exhibits introduced iMessages between Magbanua and Charlie Adelson concerning her work availability and office-logging instructions, admitted over hearsay objection as impeachment. A color-coded demonstrative showed the government played only a fraction of approximately 400 intercepted calls. DeCoste advanced a "pawn theory" — that Charlie used the bump naming "Katie" to deploy Magbanua as an unwitting intermediary — which Sanford categorically rejected. The cross concluded with the playing of Defense Exhibit 28, a recording of the May 27, 2016 first Rivera interview in which Sanford's own voice tells Rivera that the "person in the middle" could get him something. After initially denying he offered a reduction, Sanford conceded: "I didn't say reduction, but maybe — maybe time off is possible."
On redirect, the prosecution reframed key defense exhibits: surrounding iMessage context established that Magbanua's "availability" text (Defense Exhibit 3) concerned scheduling wisdom teeth extraction by Charlie Adelson, not Adelson Institute employment. Sanford defined "walling off" — a conspirator deliberately withholding information from associates — and confirmed the structure ran bidirectionally: Magbanua never named Garcia or Rivera to Charlie, and never named Charlie to Garcia. Sanford confirmed Magbanua's 2019 sworn statement of ignorance was "inconsistent" with what the enhanced Dolce Vita recording reveals, over a defense objection Wheeler overruled.
Following Sanford's testimony, prosecutor Cappleman formally announced that the State rested. With the jury dismissed for the evening, defense counsel DeCoste raised an unplanned disclosure: ASA Dugan had spoken mid-trial with defense witness Trooper Downing, whose account of whether Rivera was alone during a traffic stop appeared changed, supported by a new database screenshot provided to the defense just before the State rested. DeCoste placed on the record his belief the contact was an attempt to alter Downing's testimony. Judge Wheeler declined to entertain the coaching allegation, found no intentional withholding because the document was new to the State the same day, ruled the defense not prejudiced, and ordered Downing available for interview the following morning.
