Bad Blood

When a restaurant employee is knifed and killed in alley, a suspect seen on a security camera turns out to be Maria's drug-addicted brother, Jave (Kirk Acevedo). It turns out Jave was the intended target of his former dealer, and the restaurant employee was simply in the way, so Jave agrees to help Maria and Danny collar the dealer. Elsewhere, a police dog is accused of attacking an 8-year-old boy in a lawsuit levied against the NYPD, and Frank goes to great lengths to prove the dog's innocence and save him from being put down. Also, at a funeral for a former cop and friend of Henry's who has died of cancer, the deceased man's daughter approaches Henry with suspicions that her mother may have committed euthanasia.
