The pope and Emanuela Orlandi: Vatican back in the spotlight over mystery of missing girl

She was 15 when she was last seen alive in Rome. Her brother explains why he backs a new theory featured in a TV show

Not long before she disappeared in the summer of 1983, Emanuela Orlandi went to Piazza del Catalone, a small square just outside of the Vatican walls, to meet friends.

There was still a party vibe during that sweltering June just a few weeks after AS Roma clinched the Serie A title. In a photograph taken at the time Orlandi, who was then 15, is wearing a headband in yellow and red, the football team's colours, that her mother had made. It was one of the last photographs taken of the teenager before she vanished without trace on 22 June 1983, an image that has come to define the campaign of her older brother Pietro Orlandi's unrelenting search for the truth.
