S1·E11 Bad Blood

A moral coalition leader's gay son is found murdered on the roof of his apartment building. Initially, Benson and Stabler investigate his father, a Conservative well-known for his homophobic viewpoints, but once they start looking into the young man's living arrangements they realize the person they're looking for may be closer than they think. Munch tries to help Benson find the man who raped her mother, and could potentially be her father.
