After her attack, Pauley told ET that she had cried all night.
"He told me he was going to kill me several times and I absolutely believed him," she recalled. "I prayed as hard as I've ever prayed for anything ever in my life, and I didn't do anything. I thought, anything I do would escalate the situation -- I couldn't overcome him, he was stronger than me."
"I took a pen and I immediately, in shock, like drew a picture of the guy, 'cause I didn't have a camera," Pauley added. "The guy looks exactly like the thing that I drew."
