Detective Madsen calls Sam to tell him the Len has been killed. When Sam and Dean arrive to the police station to see the body, Detective Madsen tells him them he thought one of the victim's family committed the murder, but is unconvinced as the killing didn't feel like revenge, but rather looked too clean, like an assassination.
