A man was arrested on a charge of indecent assault after being accused of abducting three young girls and attacking them at the same time, according to police in the United Kingdom.
Now, 60-year-old William McMahon of Plaistow, has been sentenced to serve 18 years in prison after pleading guilty to three counts of false imprisonment, three counts of indecent assault and one count of buggery.
According to the police investigation, the three girls aged between 12 and 13, had been playing in an area known as Devil's Canyon, an abandoned morgue where young people would often meet and play.
McMahon trapped the girls in the abandoned building, telling them to face the wall.
He did everything he could to disguise his identity, including making the girls put their clothes over their heads and giving them false information about himself.
McMahon was identified as the perpetrator when a DNA sample was taken from him for unrelated matters. One of the victims died from an unrelated illness.
