Background

Allen married Samantha Strahan in 2016, and they lived together in their RV trailer home. Late at night on April 9, 2020, Samantha and her mother, Brenda, shared several back-and-forth phone calls. A. Mother’s Testimony Samantha’s mother testified that Samantha called her the night of April 9. She was whispering and had locked herself in the bathroom. She “sounded afraid” and she “was scared.” While crying, Samantha told Brenda that she “tried to cuddle up to [Allen] and [] he had kicked her, and she’d gone flying through the door.” Samantha told her mother that her head hurt and she felt like she had broken a rib, but she was “holding [herself] together.” Samantha said she felt “sad” and “trapped.” Brenda wanted to help but did not know how, so she recited a few Bible verses to Samantha. As they were talking, Brenda heard Allen ask, “Who are you talking to?” Samantha responded, “my mama,” and that “seemed to escalate things a little bit.” The call then ended. Brenda wanted to go over immediately, but she was afraid it

would cause a “bigger confrontation.” She testified that she and her husband had been in prior confrontations with Allen about Samantha’s “safety.” Brenda eventually got a text from Samantha that made her believe she could wait until the morning before doing anything else.

The next morning, Brenda texted Samantha, but received no response. Later that morning Brenda received a call from Allen. He told her he had gone out to get food, and when he returned, he found Samantha unconscious. Brenda told Allen to call 9-1-1. She and her husband immediately left to check on Samantha. B. Medical Testimony When EMS arrived, Allen was on his knees near Samantha, who was unconscious. Allen told EMS that Samantha had begun having seizures a year and a half ago, but she was not taking medication. He reported that she had a seizure earlier in the week, but that “this is not how she typically acts after a seizure.” Allen said that Samantha had been vomiting with nausea and diarrhea that week. He explained that bruises visible on Samantha’s body were from a seizure earlier in the week, and others were possibly from when she was drunk.

EMS transported Samantha to a hospital in Tomball, where medical staff observed that she could breathe on her own but was “completely unconscious.” She had “bruising in multiple stages of healing across her body, across her check, on her

back, circumferential bruising on her arms and her ankles, [and] bruising on her hands.”

Laura Dunbar—an emergency room nurse on duty—testified that Samantha’s presentation was not consistent with a seizure. For example, seizure patients usually regain consciousness and show response to pain stimuli. Samantha did neither. When Dunbar spoke to Allen, he admitted that he and Samantha had “an argument” the prior night, but he did not “admit to any abuse.” He reported that Samantha was vomiting and “not feeling right,” so he went to get her food. When he returned, she was unresponsive. Allen reported that his “wife drinks and falls down sometimes” and “has seizures and ‘falls sometimes.’” Dunbar noted that Samantha had a “significant subdural hematoma” that appeared “traumatic in nature.” The injury did not match Allen’s report of falling from seizures or drinking. Dunbar concluded that “[s]uspicion for domestic violence [was] high . . . [and] [l]aw enforcement [was] notified.”

Because of the severity of her injury, Samantha was flown to Conroe Regional Medical Center, where she was treated by Dr. Robert Ellis—a trauma surgeon and chief of surgery. Dr. Ellis noted that Samantha’s CT scan showed a large blood clot around the left side of her brain consistent with “major blunt force trauma.” He opined that the force necessary to create that type of injury was not consistent with a short fall or falling from a couch. The trauma was also not consistent with a fall

from a standing position. It was a “major deceleration” event like those seen in a high-speed car accident, a fall from “a couple of stories,” or a baseball-bat injury. It would not be a small trauma that developed over time, but a huge trauma “from the moment of injury.” He acknowledged that if a seizure causes a person to fall and hit her head, that can possibly cause a subdural hematoma. But Samantha’s brain injury was not consistent with a seizure causing the initial trauma because convulsions from a seizure are “usually a low-impact kind of injury.” In his twenty-year career as a trauma surgeon, Dr. Ellis had not been called to evaluate an injury caused by a seizure. He conceded that he did not know what caused Samantha’s subdural hematoma or how it happened.

Dr. Ellis called Dr. Cyril Sebastian, a neurosurgeon, to perform emergency surgery on Samantha. Dr. Sebastian removed a portion of Samantha’s skull to relieve the pressure on her brain. Samantha was eventually transferred to a rehabilitation facility and then a long-term care facility, where she died almost three months after her initial injury.

Dr. Kathrynn Pinneri—director of Montgomery County Forensic Services—

testified about Samantha’s autopsy report, which attributed her cause of death to “[c]omplications following blunt force trauma to the head” and described her manner of death as “homicide.” She testified that a subdural hematoma the size of the one observed in Samantha head would be caused by a “fairly significant impact,”

and “not from a minor bumping of the head against a wall, or from a short fall[.]” She also noted that Samantha had “microscopic cirrhosis” of the liver, which was “likely not affecting her at this point in her life.” She noted that when Samantha was first admitted, her liver enzymes were mildly elevated, one of her “clotting factors” was completely normal, and two other clotting factors were “very minimally elevated[.]” She did not think that any of these findings would have caused unusual bleeding or prevented normal clotting. C. The Police Investigation Harris County Sheriff’s Deputy J. Herrera was dispatched with Deputy J.

Decatur to a hospital in Conroe to investigate a “possible domestic violence” case. Deputy Herrera’s encounter with Allen at the hospital was recorded on his body camera and admitted at trial. While they were talking, Allen told police that he and Samantha had argued the night before and Samantha was “sick or had a stomach ailment” the next morning; she was lying on the couch and “mumbling.”

When discussing the event the night before, Allen told police that Samantha had been drinking and that when she drinks she gets “belligerent and verbally abusive.” When Hererra asked Allen whether Samantha had “gotten physical,” he replied, “no,” but “she did throw a cup of something on me,” and that led to the argument. Allen also stated that Samantha was “throwing stuff,” which he had to

clean up. The deputies eventually took Allen out to their car to talk to him where it was more private.
