Acquaintances of the deceased victim say that the stalking of suspect A has been going on for a year and a half since they broke up.
He threatened to kill him with a weapon, and took the victim's cell phone and erased the threatening texts one by one.
[Victim's acquaintance: I deleted all the texts I had threatened in the past because I was afraid that it would be disadvantageous to me later. There were times when I threatened to kill him with a knife.]
Mr. A's meticulousness was also revealed in this crime.
When the woman fell several times with a knife, she took her phone and ran away.
It was confirmed that he carried it with him for a while and threw it away somewhere in Gangnam-gu, Seoul, and then fled to the provinces.
Police suspect it was an attempt to destroy evidence of stalking, including contact history with the woman and threatening text messages.
The police, who obtained the victim's cell phone after a search, are reviewing digital forensics.
Immediately after the crime, it was revealed that Mr. A had switched his cell phone to airplane mode so that incoming and outgoing calls could not be made.
