Sampei, an office worker, was arrested on June 14 on suspicion of kidnapping and illegally detaining Arano at the villa. He denied the allegations and claimed that he took Arano to the villa and later dropped her off at a nearby store. The pair knew each other from talking on Twitter before he picked her up at the Mito Station. Officers searched woodland near the villa and found Arano’s decomposing body near a cliff just feet from the roadside. Post-mortem examination results released on June 21 showed that Arano suffered a broken hyoid bone – the bone in the neck that supports the tongue. She sustained no other injuries and while her cause of death remain inconclusive, police claim that there is a possibility that she could have been strangled. A mattress in the basement of the villa was found together with items which indicated that someone was staying there. Sampei’s phone – which allegedly had pictures of Arano in handcuffs – was seized as evidence.
