FBI Special Agent Patrick Sanford completed his direct examination narrating wiretap calls and Magbanua's post-interview conduct, then faced extended cross-examination focused on the unrecorded Rivera proffer and a recorded exchange about whether information could produce a benefit. 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 conduct after the May 24, 2016 interview attempt, the night before Garcia's arrest. He said she did not return to the residence, that someone else later removed her belongings, and that investigators did not know exactly where she went; the testimony did not establish why she changed residences.
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. Near the end of cross, DeCoste played a recording from the May 27, 2016 first Rivera meeting and argued that investigators supplied a "person in the middle" and possible-benefit cue. Sanford disputed that interpretation, asked that the recording be considered in full context, and said he may have mentioned possible time off or that information could get Rivera something. Defense Exhibit 28 was admitted when cross briefly reopened.
On redirect, Sanford said the surrounding iMessage context apparently concerned wisdom-teeth work by Charlie Adelson, qualifying the point with "I believe." He defined "walling off," agreed Magbanua did not name Garcia or Rivera to Charlie, and said she appeared to have walled Charlie off when speaking to Garcia. Sanford also agreed that the volume and pattern of calls did not by itself prove the participants committed murder together, while saying contact spikes around significant events raised investigative suspicion. He testified that Magbanua's 2019 statement was inconsistent with what he heard in the enhanced Dolce Vita recording, 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.
