Police investigating Lee Ki-young, who was arrested for the murder of his cohabitant and a taxi driver, have completed most of the investigations of Lee's contacts in the past year.
The police said they have been in contact with most of the 380 people who have exchanged messages or phoned with Lee over the past year.
Confirmation of the remaining 10 or so is delayed due to telecommunication company problems, but it is known that there is no possibility of additional victims so far.
However, there may be victims who have not usually met each other, so the police are keenly aware of Lee Ki-young's past activities.
The police are also analyzing whether Lee Ki-young has psychopathic tendencies, and he finished interviewing with a profiler over the weekend.
It is expected that it will take some time until the final test result as a comprehensive analysis of past criminal history and childhood experience is required.
The police plan to focus on further proving the intentionality of the crime during this week when the arrest period expires.
