Several teenage black kids were teasing a postman who was delivering mail in a working class neighborhood. They had an argument while a bomb blow up from the envelope just handed in a second floor apartment. The victim who had received the package is a 62 years old cleaning man, working at university psychiatric department. His only daughter (Seline Hizli) was blinded by grief. Brooks and Casey thought at first the bombing was racially motivated, being the janitor a Jew, so they started looking up Nazi environment. Anyway the explosive was hard to be made, because the main element is mercury, something you can't buy in the store across the street and it presumed technical skills. The perp had to be found in university chemistry department (maybe) and the mercury could have been stolen from a thermostat. But what's the motive in killing a poor cleaning man?
