Opinion

COURT OF APPEALS

EIGHTH DISTRICT OF TEXAS

EL PASO, TEXAS

I. BACKGROUND

A.D. 1 was born on March 2, 2020, to Araya and her husband, Brandon. On April 12, 2021, paramedics were called for assistance and they rushed A.D., who was then 13-months old, for treatment at a trauma level hospital. Medical personnel diagnosed him as having suffered severe blunt force trauma to his head. He died four days later on April 16, 2021.

By a three-count indictment, the State charged Lake with one count each of capital murder, murder, and injury to a child. The charging instrument alleged that Lake had intentionally or knowingly caused the death of A.D., a child under ten years of age, by striking the child’s head with or against a hard object or surface. Lake entered a plea of not guilty and the case proceeded to a jury trial in which the following evidence was presented.

A. Events of April 12, 2021 Araya testified that A.D. was born at 34 weeks gestation and spent his first three weeks of life in a neonatal intensive care unit due to a small brain hemorrhage diagnosed at birth. Ultimately, the condition resolved without need for further treatment. At his regular checkups, A.D. met all the typical baby milestones after birth. On March 3, 2021, Araya took A.D. to the pediatrician for his one-year-old checkup. She recalled that A.D. was doing “really great,” and she had no concerns about his state of health. Araya generally described A.D. as a playful, sweet baby.

Araya and her friend, Allison Schneider, worked for a local hospital as housekeepers. On April 12, 2021, they were scheduled to work the same shift, from 3:00 p.m. to approximately 11:30 p.m. About a month prior, Araya and Schneider talked about a mutually beneficial arrangement to accommodate their commutes to work and child care needs. Schneider mentioned that “if her boyfriend at the time was able to watch [A.D] and [Araya] could bring [Schneider] to and from

work, it would kind of be a win/win,” because Araya would have someone to watch A.D., and Schneider’s children would not need to be awoken in the middle of the night, to ride along for her end of shift pick up. Based on the arrangement, they planned for Schneider’s boyfriend, Lake, to babysit Schneider’s two daughters—who were three years old and two months old—and for him to also babysit A.D., in exchange for Araya giving Schneider a ride to and from work. Although Lake had watched Schnieder’s children before, he had not taken care of A.D. on his own. 2 About 2:00 p.m., Araya took A.D. to Schneider’s apartment for Lake to babysit, and she picked up Schneider for a ride to work.

Both Araya and Schneider checked in with Lake during their shift. At her 5:00 p.m. break, Araya talked with Lake through a video call. A.D. was crying and screaming at the time. Araya suggested that Lake give him some juice, offering that he would likely fall asleep. At their 7:00 p.m. break, Schneider called Lake again. Araya did not see A.D. during the call as Lake said he was sleeping. Schnieder continued to text with Lake throughout their shift. At one point, Lake texted Schneider reporting that A.D. had torn a purple pillow. Schneider described that Lake seemed to be upset. Schneider told him she was not concerned because the pillow had no sentimental value to her.

Schneider and Lake continued texting, mostly expressing feelings for each other and otherwise staying in touch. Schneider noticed it took Lake a longer time to respond to her messages than his usual pattern. Sometime after 10:00 p.m., Schneider received a call from Lake. He reported that A.D. had thrown up a “red substance,” and he described A.D. as “rag-dolling.” Lake asked whether A.D. had any medical conditions. At that point, Schneider took the phone to Araya to talk with him. From there, she and Araya decided to leave work early and go straight to her apartment.

2 Lake testified he watched A.D. a previous time, referencing an occasion when Araya and Brandon left A.D. with a military friend, his friend’s wife, two other neighbors, and Lake for a period of three to four hours. A.D. was three months old at the time.

On arrival, Araya saw A.D. lying on Schneider’s futon and he was completely unconscious. As she scooped him up to hold him, she noticed that his eyes were “kind of like rolling back” and “his breathing was very gargely.” She asked for someone to call 911.

Lake spoke to the 911 operator describing that “for some reason, [A.D. was] rag-dolling,”

he was struggling to breath, and he would not wake up. When the operator asked whether A.D. was shaking or twitching, Lake replied in the negative. When the operator asked whether anything had happened, Lake responded that A.D. was sleeping earlier and, when he went to change him, the child threw up with a little bit of blood. Upon arrival, a paramedic observed that A.D. remained unresponsive, his oxygen saturation was low, his teeth were clenched, and his pupils were dilated and nonreactive. The paramedic also noted a bruise on the left side of A.D.’s neck. Based on his clenched teeth, low oxygen levels, and posturing, the paramedic believed the child exhibited signs of head trauma and they decided to divert to a trauma facility over a medical call. They transported A.D. to the University Medical Center as a Level One trauma. Araya rode with A.D. in the ambulance and Lake and Schnieder stayed behind at their apartment.

B. Medical treatment and testimony A.D. was admitted to the El Paso Children’s Hospital. Araya continued texting with Schnieder, who stayed up late with her, while Lake fell asleep. At one point, Schnieder woke up Lake to tell him that A.D. “was 100 percent brain dead.” Lake responded by telling her it was late and for her to get some sleep. After four days of hospitalization without improvement, Araya and Brandon decided it was best to take A.D. off of the ventilator and to cease all other methods of life support. A.D. died on April 16, 2021.

At trial, the jury heard testimony from a treating physician and from the medical examiner, among other witnesses. Dr. Steven Ross, a pediatric radiologist, testified about the results of an ultrasound and CT scan taken when A.D. underwent treatment at the Children’s Hospital. Ross

noted bruising in A.D.’s lungs and injuries to his brain. Based on radiologic studies, Ross diagnosed A.D. with a global-hypoxic injury to his brain, subarachnoid hemorrhage, and a depressed fracture of the left-parietal bone of the skull. Ross explained the scans had shown that A.D.’s skull was both fractured and dented, he suffered brain death, and his injuries were indicative of trauma. A.D. also suffered a contrecoup injury that caused a subdural hemorrhage to the right side of his brain despite the fracture occurring on the left side of his skull. Ross opined that a skull fracture, like the one A.D. experienced, would have been painful and would have caused a child to scream and cry. He explained the injury would have caused vomiting within 30 minutes and a severe headache. A child with a skull fracture would not be laughing or giggling after receiving such injuries. Ross further explained that the injury could only be caused by striking the skull with or against a hard object or surface. He testified that significant force was needed to cause the injuries observed and a fall from a child’s standing position would be insufficient to explain A.D.’s injuries.
