Thierry Paulin

In October–November 1984, eight other old women were murdered, mainly in the 18th arrondissement of Paris, but in neighboring areas too. The violence of the crimes was notable; some of the victims had their heads stuck into plastic bags, some were beaten to death, and one of them was forced to drink drain cleaner. In all cases, the motive appeared to be robbery. Some reports allege that Paulin singled out women who seemed unpleasant or unfriendly when he engaged them in conversation, while Paulin himself told police that "I only tackled the weakest of them."

Only Mathurin was tried for the first nine attacks and murders, receiving a life sentence, plus 18 years without parole. He was incarcerated until January 2009, while technically, Thierry Paulin was never convicted of the murders of which he was accused.

The 1994 movie J'ai pas sommeil (I Can't Sleep) by director Claire Denis was based on the Paulin case.

In early 1988, Paulin fell ill, as his body began to succumb to the effects of AIDS. Within a year he was hospitalized in a state of near-paralysis, suffering from both tuberculosis and meningitis. He died during the night of April 16, 1989 in the hospital wing of Fresnes prison.

On November 25, 1987, Paulin murdered Rachel Cohen, age 79. On the same day, he attacked an 87-year-old woman, Berthe Finalteri, whom he suffocated and left for dead. Two days later, he strangled Geneviève Germont, who would be his last victim.

In the autumn of 1986, Paulin attacked one of his cocaine dealers with a baseball bat. The dealer went to the police, and Paulin was arrested. Paulin was sentenced to 16 months of jail for the assault, spending one year in Fresnes prison. Upon his release, Paulin knew himself to be HIV-positive. However, this just increased the number of killings in what seemed like a race against time to kill as many as possible, as he knew he was on his last years.

At the same time, Paulin and Mathurin were leading an extravagant lifestyle, spending their nights dancing, drinking champagne, and snorting cocaine. In late November, they decided to go to Toulouse to stay for a few months at the home of Paulin's father. But the elder Paulin was unable to accept his son's lover, and violent fights ensued, ending when Paulin and Mathurin broke up. Mathurin returned to Paris, while Paulin tried to start his own firm of transvestite artists, a plan which failed in autumn 1985.

From December 20, 1985, to June 14, 1986, eight more old women were murdered. The police were unable to identify the killer, though the investigators had a few clues. Police determined through fingerprint evidence that the perpetrator was the same individual who committed the 1984 murders. However, in the new murders, the killer appeared to favor quicker, less cruel methods.

In 1984, after leaving the army, Paulin learned that his mother and her family now lived in Nanterre, a northern suburb of Paris. He went there to live with them, but his relationship was hostile.

On October 5, 1984, two elderly women were assaulted in Paris. Germaine Petitot, 91, survived but was too traumatized to give a detailed description of the criminals. Anna Barbier-Ponthus, 83, died after being beaten and asphyxiated beneath a pillow. Her murderer robbed her of 300 francs (about $50).

On 14 November 1982, he robbed an old woman in her grocery, menacing her with a knife; the grocer knew him as a customer, however, and he was soon arrested. In June 1983, he was sentenced to two years in prison, but the sentence was suspended ("avec sursis"), allowing Paulin to remain free.

Thierry Paulin (November 28, 1963 – April 16, 1989) was a French serial killer active in the 1980s.

As Paulin celebrated his 24th birthday, Finalteri unexpectedly recovered, and was able to give an accurate description of her attacker, stating that he was "un métis d'une vingtaine d'années coiffé à la Carl Lewis, avec une boucle d'oreille à l'oreille gauche" (literally "a mix-race man in his twenties, with hair like Carl Lewis and an earring in his left ear"). On December 1, Paulin was arrested while walking down the street when a local police inspector, Francis Jacob, recognized him from Finalteri's description. After two days in custody, Paulin admitted everything, including his involvement with Mathurin. Accused of committing 18 murders (though he claimed responsibility for 21), he was sent to jail awaiting trial.
