4. Ring Around the Rosie

Complete story — includes the ending

The team has a new boss, Luther Wainwright ( Michael Rady ), who is taking over, and the team is helping security at the mayor's rally. The team finds a dead body in an alley. On his way to the murder scene, Jane observes a man in an overcoat with a killer's eyes and alerts the team. Apprehending the man, Henry Tibbs, the team finds him with a fully loaded semiautomatic weapon and take him into custody. Jane is convinced that Tibbs is a threat, but the team has to let him go. The dead man is a photographer. His wallet and phone are found on a homeless person, who turns out to be a yesteryear jazz saxophonist who stopped playing when he lost his wife. He readily confesses to the murder, but Lisbon finds loopholes in his story. She finds evidence on the photographer's pawned memory card exonerating him. Van Pelt meets Tibbs' estranged wife, who is terrified of Tibbs and has filed for divorce. Wainwright is skeptical and decides to tackle the Tibbs situation his way. In a search of his house, Lisbon and the team find hidden ammunition. Wainwright's approach cracks Tibbs and he attacks a garden party, but is arrested. No one dies as Lisbon and the team had replaced Tibbs' ammo with blanks. Wainwright and Jane share a moment.
