Stephen Paddock Photobomb

Did Las Vegas Shooter Stephen Paddock photobomb a couple just hours before committing the worst mass shooting in U.S. history?

That's what it looks like according to this photo obtained by IHeartMedia.  The couple, whose faces are covered by emojis, were returning home with a layover in Las Vegas. They stopped at a Taco Bell on the Las Vegas strip for a bite to eat. And since it was their first time in Vegas, the couple took a photo.

The woman in the photo showed the selfie to her father and he recognized the man in the background as Las Vegas shooter Stephen Paddock.

The FBI has confirmed that the man in the photo is Paddock, according to the source who sent us the photo. The source also says that the picture was taken just 2 1/2 hours before the shooting.

Was this Paddock's twisted way of leaving his calling card? Are there more creepy photobombs out there?
