Danny and Baez investigate a homicide in which Baez's estranged brother, a former drug addict, is the lead suspect. Meanwhile, Frank learns one of his most highly decorated officers, a German Shepherd in the K9 unit, is being accused of police brutality, and Henry investigates the widow of a former NYPD pal who might have had a hand in her husband's death.
Danny and Baez are investigating the death of a young man. They check the surveillance video in the area and they see someone, and it appears that Baez knows him. She says he's a drug addict. When they get him, it's revealed that he's Baez's brother. He claims that he didn't kill the man and that he's been clean. Baez doesn't believe him but Danny does. They later learn that her brother may have been the target and the one who was killed was in the wrong place at the wrong time. Frank learns of a lawsuit that alleges that a dog from the K-9 unit attacked a boy. Garrett wants Frank not to get involved but he does. And when a friend of Henry dies after battling cancer, he goes to the funeral and the man's daughter tells him that she thinks her mother, did a mercy killing on her father. Henry decides to look into it.—rcs0411@yahoo.com
