A 19-year-old from Howard County killed his friend by slipping cyanide in the 17 year old’s Vanilla Coke last year. The jury convicted him of first-degree murder yesterday and his mother told reporters “she was “deeply upset” by the verdict, which she said leaves adolescents who take antidepressants still “at risk” for the adverse side effects the defense blamed in the slaying.” The prosecutor responded with “Many people suffer from depression. Many people are on antidepressants. They don’t go out and kill.” It also didn’t hurt her case that the boy had been planning to murder his friend for several months.
