"I was watching Picasso and Cezanne, you know, just enjoying the museum and suddenly they said, 'museum is closed' and people started running," said David Durejko.

"Then they started shouting 'get out, get out for your own safety,'" he added.
A tourist named Missy says she saw the horror unfold as everyone raced out.
"I saw like the ribbon there with 'police' written on it," she said. "Then a woman lying like sitting on the floor alive, but then I think I saw a patch of blood on the wall."
Cabana fled the museum after the attack sparking a massive days-long manhunt fueled by messages he posted on social media.
The 60-year-old was eventually found sleeping in a Philadelphia greyhound bus terminal.
Authorities learned he had set a fire in a hotel room just an hour before being found.
The fire was what prompted the psychiatric evaluation in Philly.
