This guy Committed a crime then Joined the Army to investigate his own crime

Marcel Felix Petiot was a French serial killer who got his victims by offering to help them escape France through a non-existent secret route. They were majorly wanted people.

Once the victims agreed, he convinced them that they needed to be vaccinated.

Instead of giving them vaccine, he would inject them with cyanide and then rob them of their belongings.

On 11 March 1944, Petiot's neighbors called the attention of the police to a foul stench in the area and large amounts of smoke billowing from a chimney of the house.

Fearing a chimney fire, the police summoned firemen, who entered the house and found a roaring fire in a coal stove in the basement. In the fire, and scattered in the basement, were human remains. It is believed he killed not less than 60 people this way.

He disappeared for a while, grew his beard and changed his name to Henri Valeri. He joined the military and was among those drafted to look for Marcel Félix Petiot. He was subsequently captured after someone recognized him.
