In which episode of The Sopranos is Richie Aprile murdered?

Richie Aprile is murdered in “The Knight in White Satin Armor,” the 12th episode of The Sopranos’ second season.

Richie’s death comes through a volatile domestic confrontation rather than the planned Mafia hit. After Richie punches Janice for defending his son’s dancing, Janice retrieves a gun and shoots him. Tony then helps arrange the disposal of Richie’s body at Satriale’s Pork Store.

The episode originally aired on April 2, 2000, and is also notable for advancing several major storylines: Tony prepares to eliminate Richie, Pussy’s FBI cooperation becomes increasingly clear, and Tony ends his relationship with Irina. The title itself combines Irina’s mistaken version of “knight in shining armor” with the Moody Blues song “Nights in White Satin.”

A common mix-up is “Funhouse,” the following episode, in which Tony’s suspicions about Pussy lead to another major murder. Richie’s disappearance is later explained publicly as his entering the Witness Protection Program, but viewers know Janice killed him.
