Imogen Farmer
From Tardis Wiki, the free Doctor Who reference
Ms Imogen Farmer was a "joyrider" who used an alien device to take control of other people's bodies. In 2016, she used the device to inhabit the body of Max Collins and she killed his whole family, claiming it was "just for fun".
The Coal Hill defenders took over her body and made her confess to the police that she and not Max killed his family. They then returned her to her own body at the point when the police started asking for details. She was convicted of the murder. (PROSE: Joyride)
