Best way to word this?

Okay, I would ask this on the writing spot but I'll get a quicker response on random. Right now I'm writing a police interrogation scene in my story and there's a part I need the wording for.
The story is from the first person point of view of a cop who is currently falsely being accused of abducting/possibly murdering her police partner. She is refusing to speak یا even look at the interrogator, the latter because she is silently crying over the suffering her partner is going through and is afraid it will be interpeted wrong. Right now she is half listening to the cop when another detective pops into the room with a box we later find out contains a tape of the victim being tortured and also his severed left pointer finger (but we don't know what's in the box yet) I need to figure out how to word when the other detective pops into the room with the box.
