In November 2011, Paul Frampton, a theoretical particle physicist, met Denise Milani, a Czech bikini model, on the online dating site Mate1.com. She was gorgeous — dark-haired and dark-eyed, with a supposedly natural DDD breast size. In some photos, she looked tauntingly steamy; in others, she offered a warm smile. Soon, Frampton and Milani were chatting online nearly every day. Frampton would return home from campus — he’d been a professor in the physics and astronomy department at the University of North Carolina at Chapel Hill for 30 years — and his computer would buzz. “Are you there, honey?” They’d chat on Yahoo Messenger for a while, and then he’d go into the other room to take care of something. A half-hour later, there was the familiar buzz. It was always Milani. “What are you doing now?”

Frampton had been very lonely since his divorce three years earlier; now it seemed those days were over. Milani told him she was longing to change her life. She was tired, she said, of being a “glamour model,” of posing in her bikini on the beach while men ogled her. She wanted to settle down, have children. But she worried what he thought of her. “Do you think you could ever be proud of someone like me?” Of course he could, he assured her…

Frampton didn’t plan on a long trip. He needed to be back to teach. So he left his car at the airport. Soon, he hoped, he’d be returning with Milani on his arm. The first thing that went wrong was that the e-ticket Milani sent Frampton for the Toronto-Santiago leg of his journey turned out to be invalid, leaving him stranded in the Toronto airport for a full day. Frampton finally arrived in La Paz four days after he set out. He hoped to meet Milani the next morning, but by then she had been called away to another photo shoot in Brussels. She promised to send him a ticket to join her there, so Frampton, who had checked into the Eva Palace Hotel, worked on a physics paper while he waited for it to arrive. He and Milani kept in regular contact. A ticket to Buenos Aires eventually came, with the promise that another ticket to Brussels was on the way. All Milani asked was that Frampton do her a favor: bring her a bag that she had left in La Paz.
