A team of international detectives has just 12 hours to track them down, using only the power of social media.
And that's the giveaway to this getaway. The crime is not real; instead, it is the focus of an international challenge, organised by the US State Department and intended to show the power of "crowdsourcing" - a way of outsourcing tasks to a distributed group of people. And it was won by a team from Abu Dhabi's Masdar Institute.
"We took that idea and developed it further," said Dr Rahwan. "It's all very well having people on social media tweeting messages, but to really focus their attention and to get them to actually work for a specific goal, financial incentives are the best way."
Borrowing a technique from network marketers, those signing up to the challenge were given $1 for each person they recruited.
