Arrived at the precinct.
Green was already waiting at the door, "Boss Brian, Hader has been temporarily detained. He behaved very honestly throughout, with no extreme actions."
Hearing this, Brian had a bad feeling, "Are you sure?"
Green nodded affirmatively, "Sure. Hader didn't pay for his drinks because someone stole his money. He hit someone because that person was drunk and kept insulting Hader's mother. He got angry and that's why he lashed out."
This made Brian even more uneasy.
At the crime scene of the massacre he had investigated before, the pheromones he smelled were clearly secreted by someone with XYY syndrome.
XYY syndrome is a congenital genetic disorder exclusive to males.
