Sergeant Corbitt completed two additional days of phone and cell-site analysis, including the "Dad's birthday present" text exchange and a minute-by-minute chronology of July 18, 2014; an FBI undercover agent testified about handing Donna Adelson a threatening flyer referencing the murder and confirmed she called the undercover number back; and lead investigator Patrick Sanford began presenting the post-bump wiretap calls, ending the day mid-testimony with evidence of a whispered, unrecorded meeting between Charlie and Donna the following day.
Full day summary
Day 4 opened with the continuation of Sergeant Christopher Corbitt's direct examination. Prosecutor Dugan introduced State's Exhibit 64JJ — a June 25, 2013 email from Donna Adelson's donnaharvey@gmail.com to friends, sent the same day as a "plan of action" email, confirming the relocation denial and stating there was "no chance at the appellate level for an appeal." Corbitt then walked the jury through the cell and phone evidence for the June 2014 reconnaissance trip: rental records showed Garcia picking up a silver Nissan Altima from Comfort rental on June 2, 2014, at a moment when Magbanua's cell data placed her near the same agency; she immediately called Charlie Adelson for over 25 minutes, and Charlie then called the Adelson family landline for another 25 minutes. GPS and cell data placed the hitmen near Winthrop Park, adjacent to Markel's Trescott Drive home, on June 4. The day after the killers returned to Miami without completing the murder, Charlie texted Donna "still working on Dad's B-day present," and Donna replied "I know it's a tough B-day, being 70 and all, but I know you'll come through." Corbitt linked this exchange to a March 2014 roadside call in which Donna instructed Charlie to erase a preceding text before discussing Harvey's "birthday gift" — four months before Harvey's actual birthday.
For the July murder trip, Corbitt established that Wendi Adelson — with her cell data placing her at the Adelson family Continuum residence the day after Harvey's birthday party — texted Markel on July 6 asking whether he would be in Tallahassee July 14–18, dates that precisely bracketed the murder trip. A custody schedule established in January already allocated Wendi her July 16 visitation, making the inquiry track Markel's precise availability window. On the morning of July 18, while surveillance footage showed Garcia and Rivera already following Markel at Premier Health and Fitness, Charlie called Wendi for 18 minutes and 17 seconds; immediately after the call, Wendi sent Markel a text conceding a custody argument and agreeing to his 4:30 pickup time. Markel was shot within approximately one hour. Garcia's phone went dark near the gym shortly after 9:58 a.m. and never returned to service. Corbitt also presented route analysis placing Donna at Charlie's residence around 8:59 p.m. on the murder night — corroborated by her outgoing text "Outside your house" — with approximately one hour and six minutes unaccounted for before her next cell-site event at 10:53 p.m.
During the lunch recess, Judge Everett researched the evidentiary basis for admitting a statement in which Donna allegedly adopted Charlie Adelson's trial testimony. He returned with a ruling admitting it as an adoptive admission under Jones v. State, noting additional independent grounds. Defense counsel Zelman raised a Crawford objection, citing State v. Hernandez, arguing the doctrine must still satisfy the Confrontation Clause; the judge distinguished Hernandez as limited to silence rather than affirmative agreement and overruled the objection. Zelman also raised a foundation challenge — that no evidence showed Donna had actually heard or watched Charlie's testimony — and the judge directed the prosecution to establish that predicate before the evidence would be received.
On cross, Zelman methodically extracted foundational limitations: cell tower maps show general service areas, not handset positions; the analysis involves estimation and inference; and voicemail routing duplicates were not removed from the Donna and Charlie frequency report slides, potentially inflating the communication counts shown to the jury. Corbitt independently narrowed the prosecution's "call flurry" characterization, stating he never used that term and that his analysis showed only "the potential for the exchange of information" — not elevated volume or tempo. The drive recreation drew sustained challenge: conducted eleven years after the murder, without research into road construction or 2014 traffic conditions, while Corbitt himself stopped for coffee during his own test run. The cross closed with a clean admission: cell records could not place Donna Adelson's handset at Charlie Adelson's residence on July 18, 2014. On redirect, Dugan re-anchored that placement on Donna's own outgoing "outside your house" text. The examination ended unexpectedly when Corbitt answered "Yeah" to Dugan's question about whether anything in the records gave him pause about reliability — prompting Dugan to immediately cut off questioning. Corbitt was released subject to recall.
FBI undercover agent Oscar Jimenez Jr. testified about an April 19, 2016 "bump" operation. Posing as a gang member, he approached Donna Adelson near her South Miami residence and handed her a flyer bearing a printed article about the Markel murder, a handwritten undercover phone number, and a $5,000 figure. State's Exhibits 83 and 117 were admitted; Exhibit 117 documented three answered calls — one Jimenez placed to the Adelson Institute, one from Charlie Adelson, and one from Donna Adelson, with no other calls answered during the operation. On cross, Fulford established that the bump location was chosen by the investigative team on the route Donna used to pick up her grandchildren from school, that Jimenez was instructed to be polite, and that an explicit threatening follow-up text was scripted for him by the investigative team — which Jimenez himself characterized as consistent with how "somebody that's blackmailing somebody or extorting somebody" would communicate. When Donna finally called on May 6, 2016, she denied involvement and directed Jimenez to collect the publicly available $100,000 reward for information about the Markel homicide. Neither Donna nor Charlie ever paid the $5,000 demand. Redirect consisted of a single question confirming Donna was alone — without grandchildren — at the moment of contact.
FBI Special Agents Louis Bronstein (Dolce Vita restaurant surveillance) and Brian Kendall (Matsuri restaurant surveillance) testified briefly and without defense cross-examination. Bronstein described placing concealed recording equipment approximately 10–12 feet from Charlie Adelson and Magbanua at Dolce Vita, noting that background air conditioning limited live eavesdropping; State's Exhibits 114, 115, 116, 137–140 were admitted. Kendall acknowledged his positioning at the Matsuri sushi bar beside Harvey Adelson was "probably a little suspicious" and may have been detected; State's Exhibit 131 was admitted. Audio forensics expert James McElveen explained the spatial-focus technique used to suppress ambient noise without altering the subjects' voices, and confirmed State's Exhibits 115, 116, 132, and 133 were admissible; on cross, Zelman elicited that McElveen was never provided the audio of Wendi Adelson's July 18, 2014 law enforcement interview — specifically the portion where she called Donna.
Lead FBI investigator Patrick Sanford began his direct examination. He described the independent corroboration of Luis Rivera's September 2016 proffer: Rivera disclosed that Garcia had accidentally shot a hole in the rented Prius's floorboard the day before the murder, disabling the vehicle, and that Garcia repaired it. Investigators located the resold, repainted car and confirmed the bullet hole, carpet concealment, and fuel-line repair exactly as described — a fact unknown to law enforcement before the proffer. Sanford introduced State's Exhibit 99 (wiretap recordings) and Exhibit 85 (Wire Call Summary), distributed to jurors with headsets for playback. He described the conspiracy communication chain — Rivera to Garcia to Magbanua to Charlie to Donna — as fixed and consistent in both pre-homicide phone records and post-bump reactions, with no one ever bypassing a link. He walked through the calls made in the hours after the bump: Donna's calm call to Charlie saying the approach concerned "both of us" without naming Markel; Charlie's return call using "Yelp review" cover language; a third call in which a $5,000 demand and a "TV" reference surfaced, the latter linked to Charlie's prior joke about buying Wendi a TV as a divorce present "instead of hiring a hitman"; and Charlie's call to Katherine Magbanua — made after Donna told him only that the approach referenced "an ex-girlfriend," without naming Magbanua specifically. Sanford confirmed Charlie called none of his other ex-girlfriends. The day ended with evidence that the following evening Charlie and Donna met at a waterfront table at Monty's restaurant, spoke in near-whispers for approximately 30 minutes — unusually quiet for Charlie — and the FBI was unable to capture the conversation. Sanford's examination was expected to continue into Day 5. Before adjournment, Fulford preserved a record objection that Cappleman's narration of recorded call content while the jury read a highlighted transcript constituted improper cumulative testimony; Judge Everett reaffirmed his prior ruling permitting contextualizing questions and closed the matter.
