"Annihilated" is an episode of Law & Order: Special Victims Unit. It originally aired on May 8, 2007.
A convenience store clerk recognizes Dashal from the photo and directs Benson and Stabler to his house, where he is living as Malcolm Royce along with his family. During an interview, Benson tells Malcolm that Cynthia is dead; Malcolm later says that he loves Cynthia and his wife, Lindsay. He is initially alibied from Cynthia's murder because he was at a restaurant the night she was killed, but then Fin reports that Malcolm’s car made a round-trip to Manhattan that night. Malcolm states that Lindsay was driving the car that night but that she didn’t know about the affair.
Lindsay says that she drove into Manhattan to take a break from Staten Island and her home life; later, her neighbor says that Lindsay told her that she was going to "make Malcolm pay" for having the affair. Benson and Stabler return to the house later that night and find Lindsay and all the children dead and Malcolm near death; a gun is by Lindsay's hand. Stabler then checks on his own children to make sure they are all right. Then Kathy asks him to stay the night. And they have sexual intercourse. Afterwards, O'Halloran reveals that Malcolm shot everyone himself, and Stabler goes back to the hospital and stops Malcolm from jumping off the roof before arresting him.
After Stabler tells Malcolm about the forensic proof that Malcolm's gunshot wound was self-inflicted, Malcolm says that he shot himself only after Lindsay shot the kids, and that he put the gun near Lindsay because suicide is a sin under his religion. After a further interrogation, he says that he keeps his gun in a lockbox and later admits that he killed Lindsay after she killed the kids, but he insists that he didn't kill Cynthia. O'Halloran then shows Cragen and Novak that Malcolm's fingerprints were found on the pages in a book about subluxation as well as on the lockbox, but Lindsay's were not. Stabler nearly subluxes Malcolm himself until Malcolm confesses to killing everyone; then Stabler walks out of the interrogation room in a daze.
Benson: Fifteen, twenty minutes tops.
Cragen: Okay, so he's back by 10:00. That leaves time for him to sneak out after the wife and kids go to sleep; head it to Manhattan; kill Cynthia.
Stabler: You ever try to put three kids to bed hopped up on pizza and soda?
Cragen: Well, maybe Malcolm's got the magic touch.
Stabler: Cannot be done. Trust me.
Tyler: Are you going to help my mom?
Stabler: Why, does your Mom need help?
Tyler: She's really mad and sad.
Stabler: Oh; do you know why?
Tyler: 'Cause my dad's sick.
Stabler: What's wrong with him?
Tyler: Mom says he got a dirty whore.
Kathleen: Dad, what are you doing here?
Stabler: I came by to see you guys.
Kathleen: At 2:00 in the morning?
Stabler: I had a long day.
Kathleen: It isn't fair to Mom.
Stabler: Look, I called; she said it was okay.
Kathleen: That's not what I mean. We’re your family, not some booty call. Come home or don't. There's nothing in between.
