A woman was stabbed after accusing her attacker of following her around the art fair and bumping into her repeatedly, local media reported. CNN affiliate WSVN said police had named the attacker as 24-year-old Siyuan Zhao. Zhao stabbed the victim in the neck with a craft knife, WSVN reported.
"I had to kill her and two more," and "I had to watch her bleed!" Zhao said, according to her arrest report.
The violence unfolded near an exhibit by artist Naomi Fisher, who told the Miami Herald that one witness assumed the blood was fake.
New York-based sculptor Gregg Hill also told the paper that he saw the victim being wheeled out but never suspected a genuine crime had occurred.
"People didn't really know what had happened. It was calm and everyone was milling around and talking," he said.
Other patrons were observed wandering around sipping champagne, under the impression that police tape cordoning off parts of the convention center was part of an installation.
