Dateline Episode Trailer: The Grudge | Dateline NBC

Our guard was down because that [music]. bell was ringing so often. >> It was a single male who had dressed up. like a [music] delivery person. >> The only thing I could think of is that. it was a bomb. But what I saw was as. worse as anything that I had imagined. >> They told me that it was the house of a. judge Salas. >> It's just hard to imagine that someone. would come to my door and take my only. child. It's unfathomable.

>> Our concern was where was he going next. being that this was a federal court. judge. Were those his targets? >> So you're thinking maybe this guy has a. hit list of some [music] kind. >> Yes. We are going to be having to gear up for. a pretty serious manhunt. We were really building out our. theories, but we had no one at that. time. >> The detective happened to be watching TV. and he said, "I know it's probably not. connected, [music]. but I got to ask anyway.". It was highly unlikely, but we had to. follow every lead.

>> We weren't expecting [music] to link up. a murder in California to the attack. here in New Jersey. >> This seemed like a targeted killing. >> Yes. I believe he conducted a lot of research. [music] prior to doing the attacks. >> I didn't understand the connection. >> But I thought I might be the only one on. the planet that did. >> Judges need to feel that they are being. protected, that we are going to be able. to do our jobs without fear of being. gunned down literally in our homes.
