Defense Challenges Forensic Integrity in Preliminary Hearing for Celeste Rivas Murder Case
LOS ANGELES — During a tense preliminary hearing on Thursday, defense attorneys representing the recording artist D4vd mounted a rigorous challenge against the forensic evidence presented by the prosecution. The hearing, which will determine if there is sufficient evidence to proceed to a trial in the murder of Celeste Rivas, quickly shifted into a detailed examination of forensic methodology. High-profile defense attorney Blair Berk took center stage to cross-examine Los Angeles Police Department (LAPD) criminalist Lauren Wallace, focusing heavily on the collection, preservation, and testing of what investigators have characterized as potential blood evidence.
Berk’s questioning aimed directly at the reliability of the LAPD’s scientific procedures. The defense pressed Wallace on the distinction between presumptive testing—which merely suggests the presence of blood—and definitive confirmatory laboratory analysis. Berk scrutinized the chain of custody and raised questions regarding potential cross-contamination at the crime scene, attempting to cast doubt on the accuracy of the forensic findings. Wallace defended her team's methodology under oath, asserting that standard LAPD protocols were strictly followed during both the initial scene investigation and the subsequent laboratory evaluations.
The case has garnered significant attention due to D4vd’s rising profile in the music industry. The prosecution is relying heavily on physical forensics to link the defendant to the scene of Rivas' death. By targeting the credibility of the LAPD's forensic division during the preliminary phase, the defense is attempting to weaken the prosecution's foundation before the case can transition to a criminal trial. Legal analysts note that challenging forensic integrity is a common and highly strategic move in high-profile Los Angeles cases where physical evidence is central to the state's narrative.
As the preliminary hearing continues, the court is expected to hear from additional forensic specialists, digital investigators, and potentially character witnesses. The presiding judge must ultimately decide whether the prosecution has met the probable cause threshold required to bind the defendant over for trial. Representatives for the District Attorney's office and the LAPD have declined to comment on the active litigation outside of court statements.
