Takahiro Shiraishi, a 27-year-old man from Japan, and dubbed as "Twitter killer" for allegedly murdering and dismembering nine people he met on social media, has been charged with his first count of homicide on Monday.
He lured mostly female victims in the age group of 15 and 26 to his apartment near Tokyo, where he killed them and cut up their bodies, said reports.
Shiraishi has admitted to murdering all nine and was charged with the killing of 23-year-old Aiko Tamura.
Shiraishi, who allegedly stashed bits of bodies in coolers around his small apartment, is believed to have made contact with suicidal victims on Twitter and offered to help them die.
Tamura went missing in October and then her brother succeeded to break into her Twitter account when he noticed a suspicious handle.
He then assisted the police to locate and follow Shiraishi who was arrested last month when investigators found him in his apartment with the rotten remains of nine people.
Police say Shiraishi choked Tamura on October 23 and then hanged her body inside his apartment "to murder her."
"He has told investigators that none of (his victims) truly wished to die. They merely wanted someone to talk to," a spokesman said.
