A recent landslide on a hillside led to the discovery of the remains of Park Seo-ah, who went missing in 2022. The police identified Jung In-ha, who lived in the apartment right next to hers at the time, and requested his voluntary accompaniment for a routine investigation as a former neighbor.

At the Time of Voluntary Accompaniment

When detectives arrived at the training center, In-ha was in the middle of aggression correction training for a Doberman.

He then left a low instruction of "Stay" to the Doberman he was teaching and calmly followed them out.
