I assume you think the killer was wearing the victim's black leather jacket.
In fact, the second image (throwing the body into the water) happens at the beginning of the film. The first image (hiding the body in the grave) takes place in the middle of the film.
So I don't think the leather jacket the killer was wearing was the victim's.
However, the movie I downloaded did not have Chinese subtitles and I could not understand their dialogue, maybe I guessed wrong

.
I uploaded these images because I thought "Hiding Bodies in graves" was a creative story.
The same goes for some of the other pictures I've uploaded
For example

In The movie "The Stool Pigeon," the police are following a robber. The robber took the elevator to the parking lot, and there was a woman in the elevator. Then the policeman was guarding the entrance to the parking lot, and he saw a woman driving away from the parking lot. What he didn't know was that the robber was hiding in the back seat of the car with a gun pointed at the woman.
I think it's a wonderful design. We can change male robbers into female robbers.
When the car is in a secluded area, the female robber can snap the neck of the woman she is holding, and then remove her clothes to change her disguise.
Look at the look on the woman's face in the elevator in the screenshot, she never imagined what was going to be sent to her next

In the movie "Hanna," the hero swims from his hideout to a pier,He was spotted by two cops, and he killed them.
Make the male protagonist a female agent (in a wetsuit), Change the male cops to female cops or female lifeguards (patrolling the beach).
Then add "stripping scenes"

In the Korean TV series Sweet Spy, I thought the secret service agent's finger jab at a policewoman's throat was a good move.
