A woman who requested she be called "Shan," who was vacationing from Manchester, England, said she and her friend were just feet away from Pearsall when he was shot.

"We walked out of Macy's, and we both noticed the guy next to us, becasue he had two big shopping bags. One was a Rimowa, the other was a big orange Louis Vuitton bag," Shan said via FaceTime on her way to the airport to fly back to England.

According to the police report, Pearsall said the suspect told him "give me everything you got!"

Documents show Pearsall was wearing a white gold chain valued at $30,000 and a Rolex valued at $9,000 on his wrist. He wore them during an autograph signing earlier in the day.
