Tate had been admitted to hospitals many times throughout his life, according to Trahan, and had many symptoms of being bipolar and schizophrenic. He was on an anti-depressant medication, which could have affected his manic state because anti-depressants can lead to an activation of mania while not treating his bipolar disorder. When asked whether he found Tate to be mentally ill at the time of his stay, Trahan stated, “Yes.”
Prosser’s cross examination centered around the fact that although Tate was admitted into the medical center in September 2012, they had no inclination that his mental state was poor in May, when Lisa Techel was killed. His mental state was like a rollercoaster and could have varied day-to-day, let alone month-to-month.
When Prosser asked, based on Trahan’s observations in September, what could he say about Tate’s mental state in May, Trahan answered with, “Nothing at all.”
