Too much of a coincidence?

From the BBC:

A woman who claimed she saw photos that may show soldiers abusing Iraqi prisoners has contacted police.
She told BBC One's Question Time programme she had seen the pictures while working in a photo lab in 2003, but had not told anyone.

So this woman just happened to get a ticket for Question Time and just happened to be one of the audience members selected to speak and just happened to have seen these photos? It doesn't feel right to me.
