According to the police, Thuy had five previous convictions for drug-related offenses and was undergoing mandatory psychiatric treatment at the Central Institute of Forensic Psychiatry, as mandated by the Hanoi People's Procuracy. Her psychiatric medical records indicated she suffered from recurrent depressive disorder.

However, in reality, while at the institute, the suspect developed close relationships with some nurses, doctors, and service staff. Thuy was facilitated to use a phone to contact her subordinates and direct drug dealing activities.

Following Thuy's instructions, Dang Hoang Long and Phung Anh Nguyet would deliver "white goods" (a euphemism for drugs) to customers in areas bordering Hung Yen province and Hanoi. Customers would place orders and schedule deliveries in advance via phone, social media, or the Zangi messaging app.

During the investigation, police seized nearly 100 kg of various drugs, a baton-style gun, and numerous other documents and items.
