The prosecution spent the day building its timeline case through Chief Medical Examiner Dr. Lakshmanan's detailed testimony on time-of-death science—temperature analysis, rigor mortis, and stomach contents analysis—attempting to narrow the killing window to around 10:00–10:30 PM. However, Shapiro's aggressive cross-examination systematically dismantled the prosecution's forensic certainty, revealing that after eight days of testimony, Lakshmanan could not confirm the number of killers, the number of weapons, or any precise time of death. The day also exposed systemic failures at the coroner's office, including procedural errors documented in a Siglar letter, and the controversial coaching of witnesses by a trial consultant.

• Prosecutor Kelberg admitted playing inadmissible evidence (gun incident reference) and was forced to create a redacted version of exhibit 363.
• Heated dispute erupted between Kelberg and Shapiro over sidebar statements, with Kelberg accusing Shapiro of 'posturing for the camera.'
• Siglar letter introduced, cataloguing 'dozen plus' autopsy procedural errors and lapses in the coroner's handling of the case.
• Dr. Lakshmanan testified that time of death can only be estimated as a range, not pinpointed, due to biological variability and environmental factors.
• Stomach contents analysis suggested death around 10:00–10:30 PM, but Lakshmanan refused to narrow the estimate further.
• Revelation that trial consultant 'Mr. Tuno' was brought in to coach witnesses on courtroom presentation.
• Shapiro exposed that the prosecution's 200 hours of preparation for a 'bread and butter' case yielded no definitive answers on killers, weapons, or time of death.
