At the scene, the police discovered that the front door of the house was locked, but the gate was very low, easy to jump over to get into the yard, the side door of the house had no latch or bolt, through this door you could go straight to the bedroom door of Mr. Truong and his wife.

According to the investigation results, the suspect's identifying characteristics in the case: Young man about 20 to 35 years old; height 1.65m to 1.73m; wearing a baseball cap; wearing shoes about size 40 - 41 (Vietnam size) Adidas brand, dark purple, each side of the shoe has three white stripes, the shoe collar has a white border around it; wearing gray short socks; wearing long pants and a dark shirt.

The Provincial Police Department's special investigation team was established with Colonel Pham The Tung - Deputy Director, Head of the Investigation Police Department of Hung Yen Provincial Police as Head of the team.

Units: Criminal Police Department, Hung Yen City Police, Criminal Techniques Department, Records Department, Administrative Police Department for Social Order were mobilized to participate. 17 days and nights, through 2 holidays (August 19 and September 2), but the officers and soldiers participating in the project did not have a minute of rest.

17 days and nights, also the same amount of time, the working group of Department 6, Criminal Police Department, led by Lieutenant Colonel To Cao Lanh - Head of the Department, was present in Hung Yen province, coordinating with the local police to solve the case.

Colonel Tran Ngoc Ha - Director of the Criminal Police Department was also present in Hung Yen many times. At the exact time of the incident, he, along with Lieutenant Colonel Doan Van Tien - Deputy Head of the Criminal Police Department of Hung Yen Provincial Police and the working group, went to the scene to review and re-evaluate the exact time, space, and context surrounding the scene when the incident occurred.

Based on the assessment of the case, the working groups have conducted a review of all drug addicts and suspects involved in theft. Through collecting documents, the investigation team determined that a similar theft had occurred on the night of July 27 in a boarding house near Hung Yen Pedagogical College.

That night it was raining heavily, the victim was Mr. Hieu, sleeping in his rented room without locking the door. The subject sneaked in and stole Mr. Hieu's Iphone 6 Plus that was charging on the bedside table.

Thanks to good management of the area and subjects, the investigation agency has consolidated evidence and identified the subject who caused the above theft as Dinh Cong Trang, 41 years old, residing in An Binh quarter, An Tao ward, Hung Yen city. Trang is also the number 1 suspect in the murder of Mr. Truong and Ms. Hoa.

Trang's physical characteristics were very similar to the person who murdered Mr. Truong and his wife, as described by Son and his grandfather. After the night of the crime, Trang went to Hanoi for a day, then stayed at a friend's house in Hai Duong for two days. When things were calm, Trang returned to his house in Hung Yen.

On August 29, the Investigation Police Department of Hung Yen City Police prosecuted and temporarily detained Dinh Cong Trang for theft. At the same time, they searched the suspect's house, thereby confiscating knives, clothes, shoes and some related documents. The knives in the suspect's house were sent for DNA testing at the Institute of Criminal Science.

Due to the urgent nature of the case, the officers of the Institute of Criminal Science also worked day and night to get the earliest forensic results. When the forensic results were reported: On a knife collected at Trang's house, there was Ms. Hoa's and the suspect's DNA, the forces participating in solving the case breathed a sigh of relief.

The next issue is the fight with Dinh Cong Trang for the murder of Mr. Truong and Ms. Hoa! Being a law-abiding and stubborn person, since his arrest, Trang only admitted to stealing a phone at the boarding house.

*"Thick orange peel has sharp nails"

For 3 days, the most experienced detectives and investigators of Hung Yen Provincial Police and the Criminal Police Department directly fought the murderer with a bachelor's degree in Law. With the available scientific documents and professional measures, by the morning of September 3, the subject confessed to all his crimes.

According to Trang's confession, due to his drug addiction, at night he often wandered around to see which houses were open and unlocked, breaking in to steal small items such as phones and wallets.

That night, Trang went to Truong's house, looked through the gate, and discovered that the back door was unlocked. Trang climbed over the gate, through the back door, and tiptoed into Truong and Hoa's bedroom.

At that time, Ms. Hoa's phone was charging on the bedside table. Just as Trang reached for the phone, Ms. Hoa woke up and grabbed him. Trang pulled out a knife and stabbed Ms. Hoa, who collapsed to death on the bed. Hearing his wife's screams, Mr. Truong woke up and rushed to hug the suspect. Trang used the knife to stab Mr. Truong again...

Based on the collected documents, the Investigation Police Department of Hung Yen Province Police has continued to prosecute suspect Dinh Cong Trang for murder.

* Portrait of a murderer with a Bachelor of Law degree

It is known that Dinh Cong Trang was born into a decent family and graduated from Hanoi Law University. After graduating, Trang got a job in his field - a judicial officer in a ward in Hung Yen province. But after working for about 2 years, Trang suddenly quit because he thought the job there was not suitable for him and went to Hanoi to make a living, ignoring the advice of his family. From here, Trang's long slide began.

Living a vagrant and uncertain life in Hanoi, Trang got involved in drugs. In 2009, after a period of working at a beer bar, Dinh Cong Trang met a waitress at this bar and introduced himself as Minh. Around August 2009, Trang invited the girl out and then raped her and was sentenced to 30 months of suspended sentence by the People's Court of Hai Ba Trung District.

In addition, Trang also has a criminal record for disturbing public order. Trang currently lives with his second wife, a garment worker, and their young daughter. However, because he is addicted to crystal meth and has no stable job, at night, he often wanders around to "practice" petty theft.

When he went to steal, Trang always carried a knife in case he was caught and fought back. And tragedy happened to Truong and Hoa when they woke up and found this inhuman thief!
