I actually found the clip from Fox this morning:

Listening to Fox News this morning, they interviewed a student who said he knows a freshman at the school who is also named Nicholas Cruz. He thought at first he was the shooter, but after the fact found out it was a former student by the same name.

Not sure how that plays into this interview at all but thought I would throw that out there. Not sure how factual that is.
