In the Season 9 premiere of Blue Bloods, “Playing With Fire,” NYPD Detective Danny Reagan (Donnie Wahlberg) learns that drug cartel member Louis Delgado aka The Panther is the one responsible for torching his house. (That was in Season 7 finale: Danny, his wife Linda and the boys were able to escape. Linda died later in a medevac helicopter crash.) Now, with Delgado in custody, Danny asks his sister Erin (Bridget Moynahan) — who just got a promotion in the DA’s office — for help with his investigation to put Delgado away for a very long time.
Delgado is portrayed by veteran actor Lou Diamond Phillips. He’s known for his roles in the movies La Bamba, Courage Under Fire, Young Guns (see reunion photo below), and the TV movie about real-life serial killer Richard Ramirez, The Night Stalker. Phillips is also recognized for his roles on the TV series Longmire (Henry Standing Bear), Numb3rs (Agent Ian Edgerton), and SGU Stargate Universe (Colonel David Telford). Blue Bloods airs Fridays at 10pm on CBS, right after Hawaii Five-0.
