Officer: “Anybody who’s not doing anything right now, I need to spread this perimeter out. … Our east perimeter is fine, just start getting units down to the west and lock down Walmart!”

Officer: “There’s a lot of units here on scene. If they’re not doing anything they need to get to the perimeter – we have more than enough units on scene.”

Officer: “Any units that have access to a computer or can open media that they can look up an Instagram account, it’s going to be cruz_nikolas – I’m advised that might be the suspect – he has a recent post holding a gun.”

Officer: “Anybody evacuating students, I don’t need them going west – they should be going east toward school buses. East toward school buses if you’re evaccing students.”

Search for shooter’s photo

Students at the scene provided details to officers:

Officer to dispatch: “I need a suspect’s name again – I’m going to talk to a student who may get a picture.”

Officer: “I just talked to a student, I know somebody’s looking for a photo. He should be a ginger, red hair with freckles. Always wears a hoodie, was part of the ROTC program. He’s about 5 feet 8.”

Officer: “I’m being advised by ROTC students that he was kicked out last year. We’re still looking for a photo – he worked at a Dollar Store on Magnolia. Last name spelling is C-R-U-Z.”

All student evacuees checked

There was fear the gunman could be among the rescued students:

Officer: “I’m talking to Nikolas’ caregiver. We need some units to go to his house. … He’s got a safe with guns, he doesn’t know if his wife is OK.”

Officer: “I’ve got bad radio service, I’ve got the mom. She’s 10-4. (OK) I’m going to need a couple extra units out here to secure the house. There’s possibly a male in the house, not the suspect. We’re trying to talk him out.”

‘Nikolas Cruz is in custody’

At 3:41 p.m., Cruz was arrested

Officer: “We have the suspect detained.”

Officer: “Can we get a positive identification that Nikolas Cruz has been detained?”

Officer: “10-4 – confirmed that Nikolas Cruz is in custody.”

Officer: “I’m … here at the apprehension scene. The clothing is identical. We are going to need homicide or whoever is going to be working this here on scene ASAP, especially when they’re going to do the one on one. We need investigators.”

Officer: “Also … we’ll want to send some dogs this way to do article search. You want to get them out of staging, and get them over this way?”

Officer: “We’re gonna get investigators here. … They’re going to show up and then start doing article searches to see if he dropped anything in this neighborhood.”

Additional suspects?

After the arrest, there were concerns of another gunman:

Officer: “I just want to confirm: We have no intel of any other suspects, just the one?”

Dispatch: “Any units have additional information about any potential additional participants involved in this incident?”

Officer: Positive ID. That’s the only one.
