A licensed clinical psychologist says the former Montgomery High School student accused of stabbing a fellow student to death on campus has PTSD. Doctor Brittany Cunningham testified on Thursday, in what was the eighth day of 16-year-old Daniel Pulido’s voluntary manslaughter trial. Cunningham conducted a mental evaluation of the boy in August and again in September. She says he began experiencing symptoms of PTSD in December of last year, and those symptoms only worsened before the deadly classroom fight on March 1st. Cunningham says he developed full PTSD after the incident. The trial will resume Friday at 1:30pm.
