Yvan Keller

Yvan Keller (December 13, 1960 – September 22, 2006), nicknamed The Pillow Killer, was a French serial killer. Between 1989 and 2006, he killed at least 23 people in France, Switzerland and Germany, and confessed to killing about 150. If corroborated, that would make him the most prolific French serial killer of the 20th century.
Biography
Childhood
Yvan Keller was born on December 13, 1960, in Wittenheim, Haut-Rhin. His parents were basket makers and sedentary travellers who had 8 other children, all of them living on Rue du Bourg. His father, Joseph, was employed in Alsace's potash mines. Keller grew up in a rather unstable family, as his father forced him to work hard so they could survive. His mother died at age 49.
This busy life took Yvan behind bars at the age of 17 for stealing two antiques in Battenheim in 1981. Keller was arrested and sentenced to 10 years in prison for robbery.
The man with two faces
In August 1989, Keller was released. He moved to Mulhouse on Rue de Verdun, in the apartment of an old mansion in a quiet and green area, away from the city center. He became a landscape gardener and created a small company: Alsa-Jardin. His clients were very satisfied with his work and frequently recommended him. He led a modest life, living with a woman named Marina, but they later separated and he found a new companion named Séverine.
Keller's neighbors said that he was very helpful, friendly and affectionate with animals.
Marina, Keller's first companion, said he had forced her into prostitution because he was in constant need of money because of his love for luxury, casinos, horse racing, great restaurants and big-name hotels. One of his friends said that while he was in a relationship with his second wife Séverine, she was already in a relationship with another man. When he learned of this, Keller went to see the man and put a gun in his mouth, threatening him to leave his wife alone.
Murders and subsequent investigation
In January 1994, at Burnhaupt-le-Haut, Rue Basse resident Marie Winterholer was found dead in her bed, lying on her back. The doctor concluded that it was a natural death and issued a burial permit.
On March 12, 1994, at 11 Rue Basse, a man named Germain had decided to visit his 86-year-old mother, Ernestine Mang. Just behind the door, he was surprised to find an old butter churn, which had been stored in the house's cellar for years. He then found his mother dead in bed, lying on her back. He was surprised that the bedding was flawlessly drawn, because Ernestine had trouble moving due to hip problems. Because of this, Germain was convinced that it wasn't her who had moved the churn.
On April 27, 1994, at 22 Rue Basse, 77-year-old Augusta Wassmer was also found dead in her bed, lying on her back. No break-in was observed, but her daughter Marie-Françoise Roecklin found that the bed was too well done. The autopsy concluded with a death by cardiac arrest, probably "due to great fear". Later, Marie-Françoise noticed that Augusta's bank card and a key to the house had disappeared, and that the card had been used in Mulhouse to make three withdrawals.
After his arrest, Keller claimed to be responsible for the murders of 150 people; Keller was implicated in 23 murders of old ladies, but is suspected of having killed 40.
As a landscape gardener, Keller could easily locate the houses of his victims. He killed old people so he could steal their valuables, such as money, paintings and jewels, which he would later sell to junk dealers. He would repeat the same scenario each time: he suffocated his victims in their bed, then remade the bed to perfection so it would look like a natural death.
Arrest
Between 1993 and 2003, Yvan Keller was denounced 3 times, but the first two did not follow through. The third, after 3 years of investigation, led to his arrest. Keller quickly confessed, advancing the number of victims to 150, admitting to have been active in Alsace, Switzerland and Germany. He was only indicted for five deaths: three in Haut-Rhin in 1994 and two in Bas-Rhin. Eight murders, now investigated, could have completed the list, with investigators finding similarities in other cases as well.
Death
On September 22, 2006, Yvan Keller hung himself at the Mulhouse High Court, intertwining his shoelaces to form a noose which he looped through a light fixture in his courthouse holding cell. His last words were "I just wanted to be loved."
