When fellow officer Chris Thormann (Lee Tergesen) is shot in the line of duty, his friend Crosetti takes it personally and presses a reluctant Giardello to assign him the case. A man (Larry E. Hull) claims to have witnessed the shooting and says he will testify in court. Meanwhile, Bayliss and Pembleton continue their investigation into the murder of Adena Watson, and the two become frustrated with each other when nothing new develops. Pembleton requests a new partner, but Giardello refuses. Elsewhere, as Bolander prepares for a date with Blythe, he strikes up an unusual friendship with his neighbor (Luis Guzmán), a lonely Latino cabinetmaker who has built a coffin in his apartment. Meanwhile, Howard, Felton and Lewis uncover information that helps advance several outstanding homicide cases, including that of Calpunia Church, the elderly woman suspected of killing her husbands for insurance money.
