In 1987, a double homicide case occurred in Lung Kwu Tan in Tuen Mun, Hong Kong, where two young girls were brutally murdered. Let's talk about it today.
It started at 1 a.m. on 17 November 1987, when two police officers were patrolling Tuen Mun as usual when they passed Lung Kw Beach and accidentally saw a taxi on the beach.
Curious to check, I found the taxi deep in the mud and sand, there was no one in the car, the doors were locked, but what was disturbing was that there were large blood stains on the back of the back of the seat and the side of the door, as well as on the sand opposite the door.
The police officer felt that something was suspicious, so he reported it to the bureau, and after being interrogated, the police station immediately found the driver's information according to the license plate number: Wong Sai Wai, then 32 years old, was a former police officer who lived with his wife and children at Butterfly Dance House in Butterfly Estate in Tuen Mun.
There was no report of the loss of the car, no traffic accident report, and the bureau also felt that there was a situation, and ordered the two to monitor the scene, and if anyone tried to transfer the taxi, they would immediately conduct an inventory to find out the cause and effect.
After the two took the order, they were worried about the grass and snakes, so they found a hidden place to guard the rabbit. At about 4 a.m., two young men drove a trailer over, and the police immediately went to investigate, one of whom was the driver, Huang Shiwei, who explained the blood stains on the car:
The night before, when he was driving through the intersection of Zhongwu Village, he came across a man covered in blood, claiming to have been beheaded, and asked for help to take him to the hospital, so he sent the man to Pok Oi Hospital, and after leaving the hospital, he found that the man's blood flowed on the ground of the car, just at this time the car walked to Longgutan.
He had a clever move, so he drove the car to the beach to clean it, but he didn't expect that the blood stains had not been cleaned up, but the wheels were stuck in the mud and sand, and he couldn't drive out, in desperation, he had to call a taxi call platform and call a trailer over.
After understanding the cause and effect, the police officer saw that the car was stuck in the mud and sand a little deep, and suggested that Huang Shiwei first go back to the police station with them to make a routine record, and then wait for the tide to rise before towing the car, so that it is easier to drag the car out by the buoyancy of water, Huang Shiwei is worried that the car will rust after being soaked in seawater, and some are not too willing.
Huang Shiwei's answer seemed to have no problem, but when the police casually suggested that he use buoyancy to drag the car up after high tide, his answer was obviously that he knew that the car was easy to rust after being soaked in seawater, so why not clean the blood stains on the car with clean water?
Originally, the police officer was suspicious of him, but this answer deepened his doubts, so he repeatedly said that he went to the police station.
Because of greater suspicion, after Huang Shiwei was taken back to the police station, the police questioned him in more detail, especially the time of several important incidents.
For example, what time did he meet the injured, what time did he send the injured to the hospital, what time did he call a taxi platform for help, etc., and at the same time sent someone to verify the authenticity of his confession and the taxi that investigated him.
Soon the police found that the real situation was not the same as what Huang Shiwei said, Huang Shiwei said that he encountered a person covered in blood at the intersection of Zhongwu Village, but the investigation found that no blood was found at the intersection of Zhongwu Village, and Huang Shiwei said that he sent the person to Boai Hospital.
However, the investigation showed that Pok Oi Hospital did not receive the injured, and Wong said that he called the taxi platform for help at 1:30 a.m., but the investigation showed that the taxi platform received a request for towing assistance at 11:47 am.
In the face of the police's questioning, Huang Shiwei was obviously a little panicked, but he forced himself to be calm, and the police did not force it, saying that he had more evidence in hand, and gave him an hour to consider whether to recruit or not.
In fact, at this time, the police investigated so much, and I didn't know what crime Huang Shiwei had committed, but Huang Shiwei was frightened by the police's move to retreat and advance, thinking that the police had mastered all the facts of his crime, and after the police left, he fidgeted, heaven and man were fighting, and in less than an hour, his psychology completely collapsed, so he took the initiative to explain.
At about 11 p.m. on November 16, Huang Shiwei picked up two young girls near a restaurant on Tuen Mun Township Council Road, because the two were drunk and addicted to LSD, they were a little confused, and after getting into the car, they lay down in the back seat.
He raped one on the spot, and after resting for a while, while raping the other, the girl suddenly came to her senses and shouted for help.
He was worried that the matter would be revealed, so he took the scissors placed on the front of the car and stabbed the two to death, abandoned the body under the pit in the adjacent housing area of the mining village, and then drove to Longgutan to clean the blood stains on the car with seawater, but unexpectedly half of the wheel fell into the mud, he had to call the taxi call platform for towing assistance.
The police escorted Huang Shiwei to the scene of the abandonment of the body, and sure enough, two half-naked bodies of young girls were found, and after investigation, the older one was named Liu Huimei, 17 years old at the time, a hair-washing girl, and the younger one was named He Yaxian, who was 15 years old and a salesman.
On August 9, 1988, Huang Shiwei's rape and murder trial was completed, and after six hours of deliberation by the jury, he was unanimously convicted of murder, and the judge sentenced him to death according to the rule.
Because the two police officers quietly invited Huang Shiwei into the police station at that time, and in the subsequent interrogation, the police successfully used psychological warfare to break Huang Shiwei's defense, so that the case could be solved quickly, which can be called a textbook criminal investigation technique, so this "Dragon Drum Beach Girl Double Corpse Case" was later written into the Hong Kong Police Criminal Investigation Textbook for the majority of criminal police to study and reference.
