The Texas Ranger tells the jury about what happens when someone perceives someone else as an immediate threat; the defense claims Amber Guyger mistakenly shot and killed Botham Jean, believing he was a burglar in her home.

Information from videos and phone records helped to create a timeline of Amber Guyger's movements on the day she shot Botham Jean; it begins when she went to work and ends with the deadly shooting in Jean's apartment.

Jurors listen to people who were shaken by the sound of gunshots the night Botham Jean died, and those who witnessed what happened afterward; a woman who lived at the complex tells jurors about the time she walked into the wrong apartment.

The medical examiner explained to the jury how the fatal bullet took Botham Jean's life; the jury heard from a trace evidence examiner who investigated the gunshot residue in Botham Jean's apartment.

Prosecutors accusing Yazeed Essa of murdering his wife, Rosemarie, with cyanide-laced calcium pills brought in a witness who could tell the jury about those pills. This expert broke down details about the manufacturing and bottling process. Jurors heard from Raymond Stadnick, vice president of quality control at supplement manufacturer NTBY. He told them that there were no problems on the manufacturing end with the calcium pills that Essa's wife, Rosemarie, took.

Prosecution had more questions for the manufacturer of the dietary supplements that Rosemarie Essa was taking at the time she died. The State put the focus on these calcium pills Rosemarie Essa had been taking before she died. They wanted to show that there was no manufacturing defect as they tried to prove that it was her husband, Yazeed, who tampered with them by lacing them with a deadly poison.

Two different forensic pathologists examined the remains of Rosemarie Essa and at first concluded that her death was undetermined. It took weeks before doctors linked this to a poisoning. Dr. David Dolinak told jurors his conclusion after the autopsy report: "I didn't know why she died." Next, the defendant's demeanor after he found out his wife had died was brought back up for the jury. Dr. Dolinak recalled what he considered unusual conversations with Yazeed Essa.

The cross-examination began on the forensic pathologist who did the autopsy on Rosemarie Essa. Dr. David Dolinak testified that it was her brother who told investigators that she was taking calcium pills. This turned investigators' attention to the supplements, and they eventually found cyanide in her stash of calcium capsules. After his wife's death, Yazeed gave cyanide-laced calcium pills to police just days before he fled the country in alleged panic and embarrassment.
