Donald Flack Jr.
Detective Don Flack (badge #8571) is portrayed as the legal muscle for the CSI: NY team, similar to the roles of his Las Vegas and Miami counterparts Jim Brass and Frank Tripp.What he lacks in "book knowledge" he makes up with his street smarts and policing instincts, which often prove equally helpful to the investigation.Flack is a homicide detective with the NYPD, known for both his dry wit and his determination to hunt down suspects, even to the point of chasing them down alleys and over rooftops.After Stella Bonasera is attacked in her apartment by her unstable boyfriend, Flack gently helps her through the aftermath when he comes to the hospital to take her statement (episode 2.21, "All Access").In season six he shows up to work in sweatshirts and jeans, as opposed to his usual suits, dress shirts, and ties; and Stella notices that he has stopped shaving.Flack accepts the invitation, but is unable to let himself join the festivities; after sitting in his car outside the Angell home for a while, he drives away without anyone in the house knowing that he had been there (episode 6.03, "Lat 40° 47' N/Long 73° 58' W").Later, Flack is instrumental in the safe resolution of a crisis when he and another officer successfully rescue the infant daughter of an angry and upset young deaf man holding hostage the baby and his dead girlfriend's mother.As a child he would sometimes play in a hedge maze at the Queens Botanical Garden, where he later investigates the death of a Chelsea University student, though he says that by that time he hadn't been there in years (episode 3.15, "Some Buried Bones").His mother used to make corned beef every Wednesday, and Flack claims that he would "endure every one of [his] brother's insults for one more taste of that paradise" (episode 4.04, "Time's Up").They would often share an old Walkman on car trips, much to their father's disapproval, and listen to their favorite song, "Red Rain" by Peter Gabriel (episode 5.07, "Dead Inside").
