Nine victims who were killed and dismembered by a 27-year-old Japanese man, have been identified, including four teenage girls with the youngest aged 15.
The other five were four women in their 20s and a 20-year-old man, police said early on Friday, following the discovery last month of the nine victims' dismembered bodies in the man's apartment in Zama City, southwest of Tokyo, Kyodo News agency reported.
The suspect, named as Takahiro Shiraishi, told police he had become acquainted with the eight women, including three high school students, through social media and lured them to his room before killing and cutting up the bodies, Kyodo reported.
Shiraishi, who was arrested last month, used a Twitter account to contact people with suicidal thoughts, Kyodo reported last week, citing unnamed investigative sources.
Shiraishi said in his Twitter profile he wanted "to spread my knowledge of hanging and be a help to those who are really in pain", the report said.
The police found the dismembered bodies in seven cold-storage containers while they were conducting a search on suspicion of the man's involvement in the disappearance of a 23-year-old woman.
