A police officer investigating the death of Seoul Mayor Park Won-soon is on the 15th today (15th) in the morning to call the head of Seoul's former secretary-in-chief.

The Seoul Seongbuk Police Station said it had summoned the former secretary general of Seoul, as a reference, at around 9:00 am.

The former chief of staff was known as the last person to meet and talk with Mayor Park just before his disappearance.

On the 10th, Mayor Park's moratorium revealed the handwritten will of the deceased.

A police official said that former Chief of Staff was a close aide when he served as Mayor Park, and that he should be investigated in the course of handling the incident.

In addition, he added that the people around the deceased person, such as officials from the Seoul secretariat, will be called for further investigation.

Earlier, the police started digital forensic work on the mobile phone of Mayor Park, while also applying for a communication warrant to check the deceased's live calls.

Currently, the police are holding a new iPhone from the place where Mayor Park was killed.

The mobile phone used by Mayor Park may be a clue to resolving suspicions such as whether the deceased person was actually leaked in advance or if it was leaked and what route was taken.

However, the police said that the forensic and correspondence investigations, including the investigation of the summons of the secretaries in the secretary's office, will be limited to the matters related to the incident.
