Jury Hears Defense Expert in Tanner Horner Trial
30 Apr
Summary
- Jurors weigh death penalty or life without parole for Tanner Horner.
- Defense expert's assessment of Horner's mental state challenged.
- Inmate testimony addresses future danger for Horner's sentencing.

The Tanner Horner trial's 14th day saw intense courtroom exchanges as jurors consider sentencing. Prosecutors cross-examined Dr. Eileen Ryan, a child forensic psychiatry expert, questioning the basis of her opinions on Horner's diagnoses and mental state at the time of the crime.
Prosecutors highlighted actions suggesting planning, attempting to counter the defense's mitigation arguments. The defense then presented witnesses who knew Horner, describing him as socially awkward but not violent. A former supervisor recalled Horner struggling with job demands and receiving financial help.
A fellow inmate testified about Horner's behavior in jail, noting he struggles with social cues and hasn't shown violence. This testimony aimed to address concerns about Horner posing a future danger if spared the death penalty.
Later, Dr. Julian K. Davies testified about fetal alcohol spectrum disorders. While Horner's mother’s affidavit detailed alcohol use during pregnancy, Davies concluded Horner does not meet the criteria for Fetal Alcohol Syndrome, instead identifying moderate brain dysfunction.
