MEMORANDUM OPINION

A jury found Appellant Chad Wayne Gillen guilty of the offense of murder and assessed his punishment at seventy years’ confinement. In his sole issue, Gillen argues that the trial court erred by refusing to include instructions to the jury on lesser included offenses. We affirm.

A. Background Facts

Gillen lived with his mother, Karen, and helped care for her after his father’s death. In February 2012, Karen went to a neighbor’s house and said she was freezing because Gillen would not turn on the heat. Karen stayed the weekend with her neighbor but returned home on Sunday. Karen returned a few days later with a black eye and said that Gillen had hit her. A few days after that, she returned and said that Gillen had broken her arm. The neighbor called the police, and ultimately Gillen pleaded guilty to assaulting Karen. As a result of the assault, Karen was unable to care for herself and was placed in a care facility.

Karen eventually left the care facility and moved into an apartment with a private caregiver. While living with her caregiver, Karen began having visitation with Gillen. The visitation progressed to where Karen would spend the night with Gillen but return to stay with the caregiver during the day. One day Karen returned to the caregiver after staying with Gillen, and she had a bruise. Karen told the caregiver that Gillen had caused the bruise. The caregiver had observed Gillen intentionally hurt Karen in the past by purposely stepping on her toe. In 2015, Karen left the caregiver and returned to her house to live with Gillen.

Gillen and Karen regularly attended church after she returned home.

People at church noticed occasional bruising on Karen but did not observe anything out of the ordinary for an elderly person. The church pastor was more troubled by Karen’s weight loss and frail appearance than any bruising. When the COVID pandemic struck in the spring of 2020, church services were suspended, and few people saw or spoke to Karen after that.

On September 23, 2020, Gillen took Karen to a local hospital. He left Karen in the car and went inside to get help. Courtney Dansby, an ER nurse at Baylor Scott and White, went with Gillen to his vehicle and observed that Karen was very cold and her body was stiff. Karen was rushed to a room, but no CPR or interventions were performed. Karen had a body temperature of 92.2 degrees, and she weighed 80 pounds. Dansby stated that Karen had numerous injuries including multiple bruises on her face and forehead as well as a laceration on her nose. Her right shoulder appeared to be broken or dislocated. She had multiple bruises and skin tears on her arms. Karen also had bruising on her back and ribcage area. Gillen told Dansby that Karen was breathing on the way to the hospital, but Dansby believed that Karen had been dead for some time. According to Dansby, Gillen was very calm and “nonchalant.” She described his behavior as odd for a person with a critically ill family member.

Dr. Dustin Corgan was working in the ER when Karen arrived. He described the whole situation as unusual because he was called to pronounce Karen dead rather than perform life-saving measures. According to Dr. Corgan, Gillen’s description of what had happened was not consistent with what he observed when viewing Karen’s body. Gillen stated that he was upstairs and heard a thud. He came downstairs to find that his mother had fallen, but she was still alive. He took her to the hospital, three miles from their house, and she became unresponsive en route. Upon arrival at the hospital, nurses went to Gillen’s car and found Karen’s deceased body in the car. When he initially saw Karen, Dr. Corgan observed that she had been dead longer than a few minutes. Because of the unusual circumstances, the police were called to come to the hospital.

Waxahachie Patrol Sergeant Corey Kaelin responded to the call from the hospital. Sergeant Kaelin observed multiple injuries on Karen. Sergeant Kaelin spoke to Gillen at the hospital, and he was cooperative. The interview was continued at the police station. Gillen told police that he had left the house around 1:00 to go to the mall. He returned around 4:00 and asked Karen if she would like to eat. Karen said she would eat after Gillen returned from church. Gillen returned home from church around 8:00 and fed Karen. He then bathed her and put her on the couch where she slept. He went upstairs to shower, and

he heard a thud. He returned to find Karen on the floor. Gillen put Karen in the car and took her to the hospital. On the way to the hospital, Karen slumped over.

After interviewing Gillen at the police station, Sergeant Kaelin and Corporal Meagan Gonzalez went with Gillen to his house. According to Sergeant Kaelin, the house was filthy and smelled of urine. The couch where Karen slept was stained with dried blood and smelled of urine. There were also blood stains on the walls of the house. Sergeant Kaelin measured that the couch was approximately eighteen inches off of the ground.

The officers found a broken broom handle at the residence that had a jagged edge. The broom handle appeared to have blood, hair, and skin particles attached to it. The officers sent the broom handle for testing. Testing conducted on the broom handle was positive for blood. Testing further revealed that Karen was 14.2 quadrillion times more likely to be the source of the DNA found on the broom handle than the probability of an unrelated, unknown source.

Gillen told the officers that Karen bumped into the walls with her wheelchair causing the bruises and cuts on her arms. He explained the bruises on Karen’s face occurred when she fell off of the couch on more than one occasion. He admitted to the police officers that he had punched Karen in the

stomach when she would not eat and that he bit her on the forehead. He also confessed that two weeks before her death, he struck Karen in the arm, shoulder, and possibly her head. He also stated that he had hit her in the face.

Dr. Allison Cooper performed an autopsy on Karen. Dr. Cooper testified that Karen was underweight and appeared older than sixty-eight years old. Dr. Cooper observed that Karen was frail and had multiple injuries that were evident. Dr. Cooper described the injuries to Karen’s face and head. She noted that Karen suffered multiple blunt force injuries to the head. Karen had a bed sore on her back and areas of hemorrhage on her back and right buttocks. Dr. Cooper noted that Karen had bruises and skin tears on her arms as well as multiple bruises on her legs. Dr. Cooper further explained that Karen had a severe injury to shoulder and upper arm.

Dr. Cooper testified that Karen suffered a traumatic injury to her brain.

She stated that her brain injury was not consistent with a small fall but required more force such as being hit in the head with something or being in a motor vehicle accident. According to Dr. Cooper, the brain injury would have at a minimum put Karen in a comatose state if not death. Dr. Cooper also testified that Karen suffered a severe abdominal injury. Karen had 290 milliliters of liquid and clotted blood inside of her abdominal cavity. Dr. Cooper said that her abdominal injury was caused by severe force.
