The retrial opened with the prosecution framing Magbanua as the link between the Adelson family and the hitmen, while the defense conceded Adelson ordered the murder and Garcia and Rivera executed it, disputing only whether Magbanua had any knowledge of the plan. Lead detective Craig Isom delivered the day's most consequential testimony, with cross-examination producing admissions that investigators provided Rivera with discovery before his cooperation proffer and that legitimate Adelson Institute employment could not be conclusively ruled out.
Full day summary
Day 1 of the Magbanua retrial opened with pre-jury housekeeping — sequestration, a mutual expert-observation exception, and exhibit logistics — followed by preliminary jury instructions on the three charges, the reasonable-doubt standard, and the no-adverse-inference rule.
In the prosecution's opening statement, ASA Sarah Kathryn Dugan structured the State's case around two independent investigative paths — motive through the Adelson family's custody dispute with Dan Markel and physical evidence through the rental Prius seen leaving the scene — presenting both as converging on Magbanua as the intermediary between Charlie Adelson and the hitmen. Dugan previewed an FBI undercover operation in which a posed blackmailer approached Donna Adelson and investigators then tracked the resulting communications flowing from Donna to Charlie to Magbanua to Garcia; the Dolce Vita restaurant recording in which Charlie Adelson allegedly discussed the rental car, assessed the state of the evidence, and expressed willingness to pay to have the blackmailer killed; and cooperating witness Luis Rivera's anticipated account of two trips to Tallahassee, the murder itself, and a next-day cash payment in stacks of $100 bills.
Defense co-counsel Tara Kawass opened with a deliberate concession: Charlie Adelson ordered the murder and Garcia and Rivera carried it out, but Katherine Magbanua knew nothing of any plan. Kawass presented an alternative narrative in which Adelson recruited Garcia directly after Garcia, who was stalking Magbanua, spotted the two together on a date — a deal struck behind Magbanua's back. She attacked the prosecution's two primary evidentiary pillars: Rivera's cooperation agreement, which she characterized as extraordinarily favorable (a murder charge resolved to 19 years served concurrently with a preexisting federal term in a federal facility), and the Dolce Vita recording, noting Magbanua's voice is inaudible for the first thirty minutes despite six years of enhancement attempts. She disclosed that Charlie Adelson had been arrested approximately one month before trial and that Wendi Adelson received immunity to testify, framing both as bearing on witness credibility.
Five prosecution witnesses followed the openings. Neighbor James Geiger described hearing a loud bang, observing a light-colored Prius rapidly backing out of Markel's driveway and speeding toward Benton Road, and entering the garage to find the driver's window shattered and Markel seated, bloody, and unresponsive. Retired TPD officer David Sims, the first law enforcement officer on scene, described Markel's condition and identified a bullet-entry pattern in the remaining window glass. Forensic specialist Joanne Maltese testified that no shell casings were recovered — consistent with a revolver — that DNA from all door handle swabs was too limited to be interpretable, and that stippling on Markel's forearm indicated a close-proximity discharge; on cross, DeCoste elicited her agreement that the stippling location was consistent with Markel raising his arm as he was being shot. Medical examiner Anthony Clark described two gunshot wounds — a survivable cheek wound inflicted first through the raised car window, followed by a fatal between-the-eyes shot at intermediate range — and placed Markel's arm elevated during the second shot based on soot deposits consistent with a reflexive defensive response; on cross, Clark acknowledged he could not identify why the arm was raised and that trajectory figures assume anatomic rather than actual seated position. Forensic video analyst Brock Dietz established the evidentiary foundation for surveillance footage from Premier Gym, ATM cameras, and Star Metro buses, with publication to the jury deferred.
The day's most extensive testimony came from retired TPD lead detective Craig Isom. His direct examination established the murder timeline — a four-minute window between the Prius turning onto Benton Road at 10:51 a.m. and bus 707 capturing it heading north on Thomasville Road at 10:55 a.m. — and walked through the rental car agreement tying the vehicle to Rivera, Sun Pass toll records corroborating travel, ATM images placing both men in the car on the return trip, and the Adelson family's motive documented in a 700-page divorce file. Isom recounted Wendi Adelson's same-day interview in which she told investigators Charlie had "looked into hiring a hitman" but found it cheaper to buy a television as a divorce gift. He testified that Rivera's September 2016 proffer included a privately known detail — a hole in the Prius floorboard — later independently verified when investigators examined the vehicle; that Charlie Adelson's attorney called Isom within 20 minutes of Magbanua making her post-arrest phone call; and that Adelson Institute biweekly checks to Magbanua, signed by Donna Adelson, began in September 2014 with no supporting employment documentation produced under subpoena.
On cross, DeCoste extracted a series of concessions: Isom acknowledged Magbanua was the investigation's focus because she was the only identified connection between Garcia and the Adelsons; that detailed investigative reports were provided to Rivera's defense attorneys in discovery roughly two months before Rivera proffered, and that Rivera could have used that material to corroborate his account — agreeing that he had "unintentionally given Rivera the script"; that the initial September 30, 2016 proffer was not recorded despite recording equipment being present in the same interview room used for the taped October 4 session; and, after iCloud texts from Charlie Adelson's account were introduced showing Magbanua discussing starting work and Adelson instructing her to call his office, that he could not conclusively tell the jury she had not worked for the Adelson practice legitimately. Cross closed with confirmation that hundreds of wiretapped calls produced no admission of involvement and that Magbanua did not flee after Garcia and Rivera's high-profile arrests.
On redirect, Cappleman established that in May 2016 investigators visited Magbanua's residence intending only to interview her, but she refused to answer the door for fifteen minutes and that same day packed up, discarded her cell phone, and obtained a burner phone alongside Garcia at a Walmart. Isom testified Rivera's account named Magbanua consistently from his first uncharged statement; that Rivera supplied a detail investigators did not already know — the money drop occurred the morning after the murder — which phone records later corroborated; and that Rivera's severely limited reading ability made it implausible he could have extracted corroborating details from complex investigative reports. Reviewing the full iCloud thread, Isom concluded the "put me on the schedule" message the defense had offered as evidence of employment-start referred instead to scheduling a wisdom tooth extraction by Charlie Adelson. He closed by confirming no evidence that Magbanua actually performed work at the Adelson Institute despite the paychecks.
Day 1 ended with a ruling that Wendi Adelson's cross-examination would be limited to the scope of her direct and a signal that the defense could not independently subpoena her if her attorney indicated a Fifth Amendment invocation. Isom was placed under continuing subpoena by both sides for potential recall.
