The sister of a nurse accused of killing six people after speeding through a red light at 130 mph testified Tuesday about a series of unusual video calls made minutes before the fiery crash.

Kimberly Linton told the jury that her sister, Nicole Linton, made five video calls while driving on the afternoon of August 4, 2022, including one that lasted six minutes. During these calls, Nicole Linton spoke what her sister described as "gibberish" and "complete nonsense."

Asherey Ryan, 23, who was more than eight months pregnant, her unborn son Armani, 11-month-old Alonzo Quintero, and her boyfriend Reynold Lester were killed when Linton's Mercedes-Benz collided with their car at the intersection of La Brea and Slauson avenues. Nathesia Lewis, 42, and Lynette Noble, 38, who were in another vehicle, also died in the crash, which ignited a fireball near a gas station.

Kimberly Linton testified that her sister's demeanor during the video calls was "confused." At one point, Nicole Linton said she was going to take her daughter to school and told her sister to "pack a lunch." In another exchange, Nicole Linton stated she would be marrying Will Smith and asked her sister to "meet me at the altar."

Kimberly Linton called her other sister, Camille, immediately after one of these calls, around the time of the fatal collision. Kimberly Linton told the court that she blamed Camille for "triggering Nicole" by texting her days earlier during an emotional conversation. During a recorded call played in court, Kimberly told Camille, "You know she’s not well." Camille responded, "I don’t know she’s not well I’ll never text her again."

In the days preceding the crash, Kimberly Linton observed Nicole Linton "cleaning obsessively." She also recalled an incident where Nicole Linton "popped up" naked on a video call, an act Kimberly described as "unusual."

Relatives of the victims reacted emotionally during the trial. The jury was shown graphic video of Ryan's unborn baby and photos of the victims' burned bodies, prompting some family members to leave the courtroom. Prosecutor Brittany Vannoy stated that the baby was "ripped from her womb" and that the victims' bodies were "incinerated."

Tonya Boyd, a witness who attempted to provide CPR to baby Alonzo on a gas station counter, testified about the infant's condition. Linton, who had been visibly emotional, gasped and sobbed loudly, leading the judge to order the jury out of the room and instruct Linton to "compose herself."

Boyd described the baby as limp, mushy, and not alive, with blood coming from his neck. A photograph of the 11-month-old on the convenience store counter was shown, eliciting further emotional responses from the victims' families.

Linton faces six counts of murder. Her defense has argued that she experienced a seizure and lost control of her vehicle. She waived her right to testify after the defense rested its case. The jury is expected to begin deliberations later this week or next.
