The flashbulbs were oddly silent as the four models sat inside a photography studio, waiting for their moment to arrive. Never mind that the studio was in Delaware; this was high fashion meets old money. The models had been carefully selected by casting agents representing the London-based bank Barclays to star in a print campaign pitching the Barclays-branded Visa and MasterCard to a prospective corporate client—Ralph Lauren. For the models, it was a chance to be seen by the Ralph Lauren tastemakers, perhaps even the patriarch himself, a possible stepping-stone to becoming a face of the prestigious fashion company. Yet well past the scheduled start time, Barclays' creative director was calling a casting agent in a panic. "Keyon isn't here!"

Keyontyli Goffney is striking in a way that makes both women and men take notice—he's black with a trace of Thai, and has brown eyes, angular cheekbones, and a lean, chiseled body. At 26, he had the portfolio of an up-and-comer, including a Nike ad. He had also done extra work on television: as a lifeguard in a Lifetime miniseries starring Rob Lowe, on Law & Order, and as a dancer next to Tom Brady in a Saturday Night Live sketch. But Keyon wasn't content to be a backdrop for Gisele's quarterback husband; he wanted to be the next Tyson Beckford, to achieve his own stardom by doing Polo ads. The Barclays campaign could be that elusive big break, and he was missing.

The casting agent phoned Keyon's talent rep, who was stunned to hear her client was a no-show. Soft-spoken and polite, he was generally punctual. The rep tried every number she had for him and got only voice mail. Days passed before Keyon finally called to apologize. His grandmother had fallen ill, he said, and he had to take care of her. It was hard to argue with putting family first, but was there really no one else who could tend to his grandmother so he didn't miss the biggest job of his career?

The following week Keyon's rep received an e-mail from Barclays. She clicked on a link to a news story and saw photos of her client and his identical twin brother, Taleon. It turned out that while the casting agent had been scrambling to find a replacement that February day in 2008, Keyon had been busy at a shoot of a different sort. Beside his mug shot was a headline identifying him as one of the "Twin Brother Bandits." He had been caught in the middle of an alleged rooftop burglary and was a suspect in dozens of similar break-ins across three states.

Instead of getting a good night's rest on the eve of the Barclays–Ralph Lauren gig, police say, Keyon was sitting in a blue Passat, anxious for his brother to emerge from a beauty shop deep in South Philadelphia, in the gritty Italian Market made famous by Rocky. According to the police, Keyon clutched a direct-connect cell phone and scanned the darkness for "Jake," the code word he and Taleon had come up with to refer to the cops. As Keyon stood watch, his brother, dressed in black, scaled a wall of Yo! Beauty Supply with a sack of cutting tools. He sawed through the roof, lowered himself into the building, and, police say, hacked open the ATM. Moving swiftly, he slipped into the wings joint next door and, within minutes, allegedly cleaned it out, too.
