Day four of Isaac Apodaca’s murder trial ended not with a bang from the jury box, but with a gavel. After prosecutors caught Apodaca circumventing the jail’s phone security system to place unauthorized calls from his cell block, Judge T. Glenn Ellington ordered him removed from general population and placed in administrative segregation for the remainder of the proceedings. It was a punishing coda to a day that had already dealt the defense two setbacks — one over a detective’s characterization of the case as a “conspiracy,” and another over the very phone records the defense insisted did not exist.
Apodaca, 29, stands accused of first-degree murder and conspiracy in the 2022 killing of 21-year-old Grace Jennings, who was stabbed and slashed to death with a broadsword in a detached garage on Santa Fe’s south side. Prosecutors say Apodaca did not wield the weapon himself but manipulated his then-girlfriend, Kiara McCulley, into carrying out the killing. McCulley has already pleaded guilty to second-degree murder and conspiracy as part of a cooperation deal.
The Digital Footprint: A Fight Over ‘Conspiring’ and a Contested Interview
The morning session opened with defense attorney Jay Nair asking Judge Ellington to strike a single line from Apodaca’s recorded police interview: Sergeant Javier Vigil’s remark to Apodaca that “these messages look a lot like there’s some conspiring going on.” Nair argued the comment amounted to a legal conclusion dressed up as interrogation dialogue — the kind of statement that risks telling jurors what to think about an element of the very charge they are meant to decide for themselves.
Chief Deputy District Attorney Haley Murphy pushed back, characterizing the line as a standard interrogation tactic, not expert testimony or a courtroom finding of fact. Detectives, she argued, are permitted to confront suspects with their own interpretation of the evidence in order to elicit a response; the jury remains free to accept or reject that interpretation entirely.
Judge Ellington sided with the state. The comment would stay in, he ruled, with the determination of whether the elements of conspiracy were actually met left squarely in the jury’s hands. It was a modest procedural win for prosecutors, but a meaningful one — it kept the interview, widely regarded as one of the state’s centerpiece exhibits, intact and unredacted heading into testimony.
Behind the Investigation: Vigil’s Interview, the Digital Trail, and a ‘Bizarre’ Co-Defendant
Much of Day 4 belonged to Sergeant Vigil, who walked jurors through the morning of October 29, 2022, when he read Apodaca his Miranda rights and secured his consent to search his phone. That consent proved consequential: it opened the door to the Facebook Messenger exchanges and text messages between Apodaca and McCulley that prosecutors say chart a monthslong plan to kill Jennings, preserved and extracted as part of the digital forensics process described earlier in the trial.
Vigil also testified about his interactions with McCulley during her own interrogation, describing behavior he found notably unusual — she appeared, in his account, to talk to herself and to display conduct he characterized as bizarre. The defense has previously suggested that some of McCulley’s post-arrest statements, including her claims about a secretive vigilante organization called “Ghost,” reflect a level of instability that undercuts her reliability as a witness. Prosecutors, for their part, have argued that Apodaca knowingly exploited that same instability to engineer Jennings’ death — a dynamic that made Vigil’s account of McCulley’s demeanor significant to both sides’ theories of the case, for different reasons.
It bears noting for the record: McCulley pleaded guilty to second-degree murder and conspiracy under an agreement requiring her truthful testimony against Apodaca, and she has not yet taken the stand in this trial. Her credibility, and the extent to which her behavior in 2022 reflects genuine instability versus a strategic narrative, remain open questions for the jury to weigh once she is called.
The Courtroom Climax: A Voice on the Line, and a Judge’s Swift Response
The day’s most dramatic turn came in the afternoon. The defense had maintained that Apodaca made no jail calls at all, telling the court he had effectively been locked out of the facility’s phone system. Murphy countered with jail logs showing a string of calls originating from Apodaca’s cell block, C-304, to a woman identified as Linda Montoya — his mother.
The state played the recordings for the jury. According to the state’s presentation, the calls captured Apodaca speaking the phrase “United States of America” into the receiver at the outset of the call — a detail prosecutors say corresponds to a voice-verification prompt used by the jail’s phone system, and one that would have allowed Apodaca to bypass the very restriction the defense claimed had silenced him. If accurate, the recordings directly undercut the defense’s account and suggested Apodaca had both the access and the intent to communicate from inside the facility despite restrictions on his line.
Judge Ellington did not wait for closing arguments to respond. He ordered Apodaca placed in administrative segregation — commonly known as Ad-Seg, a restrictive, largely isolated housing status — for the duration of the trial, effective immediately. The order was handed down from the bench with no apparent hesitation, a rare visible rebuke of a defendant mid-trial and a stark bookend to a day that began with a fight over a single word in a police transcript.
Testimony is expected to continue this week, with McCulley’s appearance on the stand still pending. JusticeFaces.com will continue to follow the proceedings as they develop. No verdict has been reached, and Apodaca remains presumed innocent unless and until proven guilty.
