Maris has been an expert witness in a number of trials, including one in Hawaii last year in which Healy also testified. William D. Forsyth Sr., a retired businessman, stabbed his wife 17 times and then stabbed himself to death. He had been taking Prozac for 10 days. His family brought a wrongful death suit against Lilly, claiming that the company knew Prozac could make some people violent or suicidal, and failed to notify physicians about it.
