D4vd-Celeste Trial: DNA, Bluestar Evidence, and Defence Pushback Take Centre Stage

The courtroom atmosphere was tense and entirely focused on forensic science. Day 3 of the preliminary hearing for musician D4vd, legally known as David Anthony Burke, dove deep into the hidden physical clues left behind in his Hollywood Hills home. Prosecutors presented microscopic evidence, blood-detection sprays, and vehicle data to build a tighter case against the 21-year-old artist.

Meanwhile, defence attorneys pushed back hard against the methods investigators used. As the legal proceedings unfold before Judge Charlaine F. Olmedo, the details emerging from the courtroom paint a stark and unsettling picture.

Key Takeaways

• Bluestar chemical spray illuminated hidden bloodstains in Burke’s garage on floor mats, a rowing machine, a Tesla charger, and cleaning supplies.
• Blood in the garage directly matched Celeste Rivas Hernandez. A trash bag sample yielded a DNA mixture containing Burke’s profile.
• Attorney Blair Berk criticised police for skipping touch DNA tests on saw handles and noted fake blood in the home was a music video prop.
• Text records showed contact began when the victim was 11. Messages confirmed a pregnancy at age 13 followed by an abortion in January 2024.
• Prosecutors contend Burke killed Rivas Hernandez to stop her from exposing their illegal relationship and ruining his music career.
• Tesla telemetry placed Burke’s home on the night of the murder and recorded three trips to a Santa Barbara area where the victim’s passport was found.

A Stark Courtroom Scene

Burke sat quietly in the courtroom wearing orange jail attire and glasses. He remained calm throughout the testimony, frequently leaning over to consult with his legal team. Just feet away, the parents of 14-year-old Celeste Rivas Hernandez sat in the front row. They absorbed every technical detail of the forensic evidence presented by the prosecution.

Burke faces grave charges, including first-degree murder with special circumstances, child sexual abuse, and body mutilation. He maintains a not-guilty plea.

The Prosecution’s Case

Prosecutors heavily relied on advanced forensic chemistry to prove that a crime took place inside Burke’s garage.

• LAPD Criminalist Lauren Wallace took the stand to explain the use of Bluestar, a specialised chemical spray that illuminates latent bloodstains invisible to the naked eye.
• Even though the garage floor looked clean, the spray revealed positive blood reactions across multiple items. These included garage floor mats, a rowing machine, and a Tesla charging cord.
• Investigators also discovered positive reactions on black trash bags and cleaning wipes hidden inside the space. Furthermore, a crumbled blue inflatable pool recovered from the home reportedly smelled strongly of fresh laundry detergent.

DNA Evidence and Matching Profiles

Beyond chemical sprays, the state presented biological evidence to tie Rivas Hernandez directly to the garage.

• Direct DNA Matches: LAPD DNA expert Tosch testified that swabs taken from bloodstains inside the garage matched the genetic profile of Rivas Hernandez.
• Mixed Samples: A swab taken from a black trash bag yielded a complex DNA mixture from at least four individuals, which included Burke himself. Additionally, forensic tests on the cleaning wipes recovered from the property confirmed the presence of the victim’s DNA.

The Defence Strikes Back: Gaps in the Investigation

Lead defence attorney Blair Berk launched an aggressive cross-examination. She targeted potential oversights and gaps in the LAPD’s evidence-collection process.

• Untested Saws: Wallace acknowledged under questioning that investigators recovered two small chain saws and a third saw from the home. However, because initial visual tests on the blades came back negative for blood, police never collected or tested the handles for touch DNA.
• Alternative Explanations: Berk argued that the absence of blood on the saws does not clear the air. She emphasised that multiple people regularly visited or lived at the property, meaning touch DNA could easily belong to someone else.
• The Props Defence: The defence also brought up the discovery of fake blood containers at Burke’s residence. They framed these items as standard props used for his dark musical alter-ego, Itami, and his music video productions.
• Uncertain Timelines: Under further questioning, Tosch conceded a crucial limitation. She admitted she could not state with absolute certainty that the DNA samples came strictly from blood rather than skin-cell transfer, nor could she prove how long the DNA had lingered in the garage.

Digital Footprints, Relationship, and Abortion Details

Digital forensic expert Detective Corey Farell presented cell phone data, vehicle telemetry, and explicit communications between Burke and the victim.

• Timeline of Misconduct: Messages showed that contact began in August 2022, when Rivas Hernandez was 11, and Burke was 16. A sexual relationship started shortly after her 13th birthday, while Burke was 18.

• Pregnancy and Abortion: Texts from January 2024 revealed Rivas Hernandez became pregnant at age 13. Burke asked if the child was his, and she confirmed it before undergoing an abortion after two days. Later, messages showed her expressing deep emotional regret.

• Alleged Motive: Prosecutors argue Burke feared the relationship would ruin his burgeoning music career, alleging he killed Rivas Hernandez after she threatened to go public.

• GPS Tracking: Tesla telemetry placed Burke at his house the night of the April 23, 2025 killing and showed three subsequent trips to a Santa Barbara area where the victim’s passport card was later found.

Day 3 of the preliminary hearing ultimately underscored the stark contrast between the two sides of the courtroom. The prosecution relies heavily on chemical traces, biological matches, and digital tracking to prove premeditation and guilt. However, the defence continues to chip away at the reliability of the police investigation, pointing out uncollected evidence and alternative explanations for the physical items found at the home. As the hearing continues, both sides will present further arguments to determine if the case proceeds to a full trial.

FAQS

1. What is the main purpose of the D4vd trial Day 3 preliminary hearing?

The hearing determines whether prosecutors have enough probable cause to send David Anthony Burke (D4vd) to a full trial on charges of first-degree murder, child sexual abuse, and body mutilation.

2. What key forensic evidence was presented during D4vd’s trial on Day 3?

LAPD experts testified that Bluestar chemical spray detected invisible bloodstains in Burke’s garage, including on floor mats, a rowing machine, and a Tesla charging cable. DNA from these stains matched the victim, Celeste Rivas Hernandez.

3. What motive do prosecutors allege for the murder of Celeste Rivas Hernandez?

Prosecutors argue that Burke killed Rivas Hernandez after she threatened to expose their illegal sexual relationship, which would have ruined his lucrative music career and exposed him to criminal prosecution.
