DNA links 1995 Seine trunk body to defendant

A trunk drifting in the Seine became the hinge of a murder case that outlasted nearly everyone around it. Marie-Thérèse Garcia, 79, went on trial in Versailles for the kidnap and murder of her former sister-in-law, Corinne Di Dio, whose dismembered body was found in a metal chest in 1995. The case was revived only after DNA work linked hairs from the trunk to Garcia, or to another woman in her maternal line, after years in which the file had gone nowhere.

Di Dio disappeared in June 1995 at the age of 37. Days later, a chain-bound metal trunk was pulled from the river to the west of Paris, and inside investigators found the remains of a woman whose head and hands were missing. Her identity was not confirmed until 1997. Even then, the investigation failed to produce a durable case, and prosecutors closed it twice, in 2000 and again in 2008, for lack of evidence.

What changed was the scientific reach of later forensic testing. Two hairs recovered from inside the trunk became the breakthrough that brought Garcia back into the frame, and the case was reopened after telephone intercepts in 2012. Garcia was placed in detention in 2023 while awaiting trial, and repeated requests for conditional release on the grounds of age and ill health were rejected. She has said she is innocent, while her lawyer has argued that the prosecution is trying to build a murder case from scraps of uncertain proof.

The long delay is part of the story. Garcia is now being tried more than 30 years after the killing, at an age when questions about fitness to stand trial, memory, and the reliability of old evidence become central, not peripheral. The court must weigh what DNA can prove against what it cannot, especially when the evidence consists of a few hairs, missing body parts, and witnesses pulled from a world of criminal alliances that has since thinned out.

Prosecutors say the motive may have involved rivalry over a child, Romain, now 41, whose father, Antonio Marquez Gomez, is also accused and remains in flight under an international arrest warrant. That broader criminal backdrop helped keep the case alive, but it also exposes the ethics of very late prosecution: cold-case justice can reach farther than before, yet the farther it reaches, the more it depends on aging defendants and evidence that has had decades to degrade, narrow, and harden into competing stories.
