Mercury
Mercury is a key person of interest in the decades-old case of Cheryl Grimmer, a British girl who disappeared from a beach in Australia in 1970. Despite being charged with her abduction and murder, his trial collapsed due to the inadmissibility of a confession made during his teenage years. Now, Cheryl's family has issued an ultimatum for him to come forward and answer their questions regarding the case.
