TRANSCRIPT: News 13 producer talks about phone call with Mateen 6-12-16 (Updated 6-15-16)
(excerpt)
“It was at 2:45 when I had just received the phone call of someone claiming to be the Orlando shooter. I answered the phone as I always do, ‘News 13 this is Matt,’ and on the other end I heard, ‘Do you know about the shooting?’ and I said ‘Yup, I’m getting information — I’m receiving some calls right now’ and he cut me off and said, ‘I’m the shooter.’ I didn’t know what to say, it was alarming to say the least. He sounded really calm on the phone and he started saying that he did it for the Islamic State — he did it for ISIS, and then he started speaking in a foreign language which at the time, being in Orlando, I thought it was maybe Spanish. But he was speaking so fast I didn’t know what it was, and thinking back now it was most likely Arabic, that he was speaking. I said ‘Sir, sir can you please speak in English?’ and then he started saying ‘I did it for ISIS, I did it for the Islamic State’ again. I didn’t know what to say to him. I was just blown away, and I asked him ‘Who is this? Where are you?’ and he told me that’s none of my effing business. He wouldn’t tell me who he was, he wouldn’t tell me where he was, but he wanted me to know that he did this for ISIS, he did this shooting for the Islamic State.”
There is a big difference between Arabic and Spanish, even when spoken fast. If only this producer would have known that difference, it would have helped determine whether the call was a prank or legitimate.
