Day 3 closed out Luis Rivera's three days on the stand, with cross-examination surfacing a gun-count contradiction, an unsworn throwaway-phone claim, and a disputed third-trip reference, while redirect rehabilitated his independent corrections and elicited his account of Magbanua directing the post-murder money pickup. Judge Wheeler ruled co-conspirator statements admissible through the payment date in a murder-for-hire. Rental records placed Sigfredo Garcia in Miami in June 2014, and Sergeant Corbitt's cell-site analysis traced Garcia's phone to Markel's gym the morning of the murder, documented a two-hour phone blackout covering the killing, and showed Magbanua as Garcia's most-called contact and Charlie Adelson's second most frequent — with her own iCloud saving Rivera's number under the nickname "Tato." A discovery dispute over untimely jail call disclosures produced a Richardson hearing set for Monday.
Full day summary
Day 3 opened with a defense objection before the jury was seated: Tara Kawass placed on the record that the State had handed over amended discovery that morning — recordings of jail calls — after the jury had been selected and opening statements delivered, leaving defense counsel no time to review. Prosecutor Cappleman acknowledged she had not yet reviewed the calls herself and offered to advise the court Monday on whether she intended to use any. Judge Wheeler ordered that the calls not be used that day, directed both sides to review over the weekend, and scheduled a Richardson hearing for Monday to determine whether a discovery violation had occurred and whether the recordings would be admitted.
Before Rivera's cross resumed, Judge Wheeler ruled on two procedural questions: immediate clip playback for impeachment is permissible only when the witness has already given a directly contradictory answer; equivocal or non-responsive answers require the standard pre-showing procedure first. The parties also resolved a transcript accommodation for Rivera's illiteracy, allowing defense counsel to read quietly to him at the stand if needed, with headphone audio as a fallback.
Also before the jury was called in, Wheeler issued a hearsay ruling: in a murder-for-hire, the conspiracy does not end at the victim's death but continues until payment is made, citing Romani v. State and Eccles v. State. Rivera's account of Magbanua confirming the job was done over an open phone line — and her delivery of money to Rivera the next day — satisfied the foundation requirement, making the hitmen's return-drive statements admissible. Cappleman supplemented the record, cataloguing six categories of pre-murder co-conspirator statements already in through Rivera, and separately argued that Magbanua's post-murder "I know" statement was independently admissible as an admission by a party opponent. Wheeler deferred a Crawford challenge to recorded Adelson family calls to a later hearing before Agent Sanford testifies.
Continuing cross-examination, Christopher DeCoste pursued four lines of impeachment. First, he established that Rivera had testified on direct that two guns were brought on the murder trip but revised that to one after hearing his 2016 recorded statement; Rivera's excuse — "eight years, who's gonna remember?" — was immediately undercut because DeCoste had just established that remembering testimony was Rivera's sole obligation since his arrest. Second, DeCoste attacked Rivera's vagueness about the gun's disposal, suggesting he was protecting himself from a federal interstate-commerce charge; Rivera, reviewing his deposition, conceded awareness of that exposure. Third, a deposition passage in which Rivera used the phrase "the first trip in June, the second trip, the third trip" prompted him to claim a separate King Anthony reconnaissance he had never mentioned in any prior sworn statement. Fourth, DeCoste built a jealousy-based alternative motive: Garcia used cocaine and alcohol daily, stalked Charlie Adelson, and nearly drove a truck through a restaurant where Adelson was dining with Magbanua. Rivera resisted throughout, insisting Magbanua was "involved the whole time" and that Garcia "does whatever she tells him to do." Rivera also broke composure during cross, snapping at DeCoste to stop repeating himself.
On redirect, Cappleman countered the theory that Rivera simply adopted the state's narrative by eliciting that he independently corrected the state on two facts absent from any police report: the payment was delivered the morning after the murder rather than that night, and the crew had shot a hole in the Prius. Rivera explained the cell-phone records challenge raised on cross by disclosing he had carried two phones that morning and had given one to Anthony, and further testified that Magbanua called him that morning and said "Who's going to come get this money?" — placing her as the party holding payment. Rivera contextualized the third-trip deposition language as speculation about who a neighbor might have seen behind Markel's house, denied participating in any third trip, and described Garcia's restaurant episode as ending without any face-to-face confrontation because Rivera talked him down. The redirect closed with Rivera acknowledging that testifying against his best friend and "his wife" is "hard" and "hurts." Wheeler twice warned Cappleman about leading questions, and multiple defense objections on leading, improper bolstering, and improper refreshment were sustained throughout.
Waldo Mesa Nunez, who worked the evening shift at Comfort Rent-A-Car in 2014 and now serves as a Florida Highway Patrol trooper, authenticated two rental agreements in his own handwriting showing a man identified as "Fredo Garcia" rented a silver Nissan Altima on June 2, 2014, then exchanged it the next day for a blue Hyundai Sonata — both paid cash at $49 per day with a $500 deposit. GPS tracking records for both vehicles were admitted alongside the contracts as State's Exhibits 70 and 71. On cross, Kawass established that Nunez has no independent recollection of Garcia — he cannot describe Garcia's appearance or how he arrived — and that the "time in" field on the exchange contract carries the due-back time from the first rental rather than recording Garcia's actual arrival. Short redirect clarified that the 8:50 p.m. timestamp on the first contract was written at the moment Nunez began it, making it Garcia's actual arrival time.
Sergeant Christopher Corbitt, a 27-year TPD veteran who has testified in approximately 80 expert cell-phone cases, then presented the prosecution's cell-site and tower dump evidence. He first traced Wendi Adelson's July 18 route past the Trescott Drive crime scene around 12:40–12:45 p.m., noting her call records showed no contact to Markel, the children's daycare, or 911 after encountering the police roadblock, and that she drove a route nearly nine and a half miles long when a roughly three-and-a-half-mile alternative was available. Tower dump analysis of Markel's stops that morning identified Garcia's Miami phone at the Premier Health and Fitness cell site at 9:36 and 9:58 a.m. Cross-referencing the dump against known subjects revealed that a Miami number present at Premier Gym on the murder morning had called Harvey Adelson's phone seventeen days earlier — on July 1, 2014 — going to voicemail for approximately 37 seconds; that number was identified as Garcia's. A frequency report on Garcia's records showed his most frequently contacted number was Katherine Magbanua's. A parallel frequency report on Charlie Adelson's records showed Magbanua was his second most frequent contact for the same period. State's Exhibit 73 (Corbitt's cell-site summary) and Exhibits 101–104 (tower dump carrier records) were admitted. A hearsay objection was sustained when the prosecution attempted to have Corbitt relay Yindra Mascaro's explanation for the Garcia-Harvey Adelson voicemail.
Resuming after lunch, Corbitt traced the prosecution's timeline chronologically. For the June 2014 reconnaissance, Magbanua's phone registered consistent with the Comfort Rent-A-Car at 8:53 p.m. — three minutes after Garcia's contract was written — with no Garcia-Magbanua phone contact during the drive, consistent with them traveling together; she then received a call from Charlie Adelson followed by a 25-minute conversation. GPS data from the rental car and Rivera's cell records placed the vehicle in the Betton Hills/Winthrop Park area adjacent to Markel's residence on June 5. For the July murder trip, Garcia and Rivera drove to Tallahassee on July 16, their phones consistent with Markel's neighborhood on July 17. On July 18, Garcia's phone registered at Premier Gym through 9:58 a.m. then went dark for over two hours covering the murder window; at 12:30 p.m., carrier notification patterns indicated the phone had just been powered back on in Alachua County, and Garcia's first outgoing call was to Katherine Magbanua. That evening, all three phones — Garcia, Rivera, and Magbanua — registered consistent with Rivera's 135th Street residence by approximately 9:46 p.m., at which point Magbanua's frequent Garcia communications ceased abruptly. On the morning of July 19, Magbanua attempted Garcia's number six times, contacted an Ortiz number, and Rivera tried Garcia before calling Magbanua; Garcia's phone showed no further active events from 7:09 a.m. onward, consistent with the phone being discarded. By 10:31 a.m., both Magbanua's and Rivera's phones were consistent with Rivera's residence, followed by a final brief call between them. Corbitt confirmed that no Adelson family handset — Charlie, Wendi, Donna, or Harvey — ever directly communicated with Garcia's or Rivera's phones, except for the single unanswered July 1 voicemail Garcia left on Harvey Adelson's line.
Outside the jury, Dugan proffered Corbitt's additional testimony that Magbanua's iCloud contact list saved Rivera's number under the nickname "Tato" — his street name — with Garcia saved as "Tuto." DeCoste challenged the proffer: he argued "Tato" is too common a nickname to conclusively identify Rivera, and he produced a defense copy of an Apple return document showing a 935-prefix number rather than the 934 number at issue, contending the prosecution relied on a separate Apple subpoena return never disclosed to the defense. Dugan acknowledged the prosecution itself had only surfaced the document at lunch that day. Wheeler ruled that because Corbitt derived the information from Magbanua's own iCloud data — already disclosed on a Cellebrite CD in defense hands — no Richardson hearing was required and the testimony was admissible. A residual question about whether the Apple subpoena return for the 934 number was separately produced was deferred pending state verification. Corbitt's cross-examination was adjourned to Monday. In a brief pre-weekend direct segment, Corbitt testified that Magbanua placed one unanswered call to the "Tato" number during the June 2014 reconnaissance trip — the first time in any records she called it — and attempted it twice on the evening of July 17, sandwiched between Garcia communications, though neither call connected.
After the jury was excused, Wheeler reconciled a clerical numbering error in the Garcia-Rivera photograph exhibits — confirming the hole-in-the-Prius image is Exhibit 48, not 47 — and previewed Monday's schedule: completing Corbitt's cross first, then Jessica Rodriguez (flagged by Cappleman as the most substantial morning witness), followed by out-of-town financial evidence witnesses, with the court prepared to extend to 5:30 p.m. if needed. The Richardson hearing on the jail calls was confirmed for Monday morning.
