The trial of Tanner Horner, who pleaded guilty to the murder of 7-year-old Athena Strand, has brought to light significant details regarding his mental health and the circumstances surrounding the tragic event.

Mental Health Evaluations

Psychiatrist Dr. Ryan testified about Horner’s emotional state, noting his intense focus on limited access to his son and his distress over court-ordered restrictions. She described him as “laser-focused” on his child and “distraught” by the limitations placed on their relationship.

During her evaluation, Horner confessed to sexually assaulting Athena Strand and revealed his own history of being raped as a child, which he stated made it difficult to discuss the incident. Dr. Ryan emphasized that Horner’s shame played a crucial role in his deception and reluctance to openly address his actions.

Dr. Ryan also acknowledged Horner’s cocaine use around the time of the crime, suggesting it may have contributed to impulsivity and impaired judgment, though she couldn’t verify the extent of his substance use.

Conflicting Accounts and Evidence

Initially, Horner claimed Athena’s death was accidental, stating he unintentionally struck her with his truck and disposed of her body out of fear of losing his job. However, dash-cam footage presented by prosecutors contradicted this account.

The footage revealed Horner engaging in casual conversation with Athena before attempting to coerce her into removing her clothes and ultimately assaulting her when she refused. This evidence painted a disturbing picture of the events leading up to her death.

Dissociative Identity Claims

Texas Ranger Sgt. Job Espinoza testified that Horner exhibited signs of Dissociative Identity Disorder, referencing an alter ego named ‘Zero’ during police interviews. Espinoza described noticeable shifts in Horner’s demeanor when he adopted this persona, including head tilting and eye-rolling.

Defense Arguments and Background

Horner’s defense team argued that his mental health struggles, including autism and childhood lead exposure, should lessen his culpability. They filed motions to exclude the death penalty, citing his neurodevelopmental condition.

Beth, a retired school psychologist and speech pathologist who previously worked with Horner, highlighted his difficulties with peer relationships, emotional recognition, and differentiating between teasing and bullying. She expressed concern that his job as a FedEx driver, requiring prolonged isolation, was unsuitable for someone with his challenges.

Dr. Amy Fritz, a speech-language pathologist, conducted a jailhouse evaluation and found Horner struggled with empathy and social appropriateness. However, she questioned the authenticity of the ‘Zero’ persona, suggesting it might be a narrative tool rather than evidence of multiple personalities.

Family Testimony

Horner’s mother testified about the family’s history of substance abuse but firmly rejected any attempts to excuse her son’s crimes, expressing both anger and disbelief at his actions.
