Only the Pretty Girls Die: Part 2 Eischied : Season 1 Episode 2

In an episode that's an obvious remake of the Son of Sam case, serial killer Albert Colvin claims his sixth victim, but without using the trademark silencer on his gun. Eischied sees this as a sign that the killer's self-control is slipping and may be a harbinger of his next planned attacks. Through clues given by Colvin to two reporters, Eischied is able to track Colvin to his final planned attack at a Catholic church.
