Why was poison bee stung to death?

A woman died in a parked car with a big bee buzzing in it.

This is a yellow Cyprus bee. Poison bee must have stung him to death on the forehead. However, no matter how poisonous bees are, will people die immediately after being stung by bees?

In fact, this is a clever use of bees to kill people. So, what means do criminals use?

Answer:

Is to use allergies.

There is a strange allergic phenomenon in the human body. If a specific animal secretion is injected into a human body, and later substances with the same composition enter the body, there will be a strong allergic reaction and death due to stimulation.

For example, the egg white of duck eggs was injected, and nothing happened at first, but one week later, the same egg white was injected and it died immediately.

The criminal took advantage of this allergy. The criminal is a doctor. He lied that the poison with the same composition as bee venom was a preventive medicine and injected the victim. A few days later, a poison bee was smuggled into the car, and the victim died of allergic reaction after being stung.
