The school trip killing: What happened to Caroline Dickinson?
In July 1996, a group of British schoolgirls travelled to Brittany on a language exchange trip. One of them, 13-year-old Caroline Dickinson, would never come home.
In the early hours of 18th July, while her classmates slept just feet away, Caroline was killed in a dormitory at a youth hostel in Pleine-Fougères. It was a crime that would haunt British families for years and take investigators the better part of a decade to solve.
Crime+Investigation examines what happened that night, the years-long hunt for the killer, and the DNA breakthrough that finally brought justice.
Slipped away in the night
The teenage schoolgirls had spent the day sightseeing as part of a language exchange and, like any excited group of teenagers, had settled down for the night after a busy day. By morning, Caroline was dead.
Caroline had been sexually assaulted and strangled while the other girls slept just feet away. Remarkably, none of them woke during the attack.
But who did this to Caroline? Investigators believed the killer had entered the unlocked dormitory sometime after midnight. The 13-year-old had been sleeping nearest the door, making her the easiest target. After attacking her, the intruder quietly left the room without disturbing the other children.
There were no obvious witnesses and little to indicate who had entered the hostel that night.
French police immediately launched a major investigation, interviewing guests, staff and local residents. Thousands of people were questioned, while detectives collected hundreds of fingerprints and DNA samples from anyone who might have had access to the area.
At first, suspicion fell on several people, including a homeless man who falsely confessed to the crime before DNA evidence ruled him out. That false lead cost investigators much-needed time, and for years the case appeared to have reached a dead end.
An international hunt
As the investigation into Caroline’s murder widened, it became one of the largest murder inquiries France had ever seen.
Detectives interviewed around 10,000 people and eventually collected more than 3,600 DNA samples. This was an enormous undertaking in the mid-1990s when DNA profiling was still developing.
Caroline's father, John Dickinson, also became a driving force behind the campaign for answers, refusing to let his daughter's case be forgotten and urging authorities to keep searching for her killer. Despite those efforts, years passed without an arrest.
The DNA recovered from the scene did not match anyone in France, leaving detectives with a profile but no suspect. It was a frustrating position. They knew the killer's genetic fingerprint, but they had no name to attach to it.
A chance arrest
Finally, there was a breakthrough almost five years after the tragic killing. It was more than 4,000 miles away.
In 2001, Spanish drifter Francisco Arce Montes was arrested in Miami Beach after sexually assaulting a young Irish woman in a youth hostel. The attack immediately piqued investigators’ interest as it closely resembled what had happened to Caroline. In both cases, the attacker entered the room where several people were sleeping, before targeting a single victim.
Montes provided a DNA sample as part of the American investigation. The profile was a perfect match to the DNA recovered from Caroline Dickinson’s murder scene. Overnight, detectives finally had the breakthrough they’d been waiting years for.
The Spanish native was extradited to France to stand trial for Caroline’s murder.
The trial and evidence
When the case came before a French court in 2004, DNA evidence formed the cornerstone of the prosecution. Prosecutors argued that the genetic match was overwhelming and placed Montes at the scene beyond reasonable doubt.
They also presented evidence of his history of sexually motivated attacks, which showed striking similarities to the circumstances surrounding Caroline's death.
Montes eventually admitted raping and killing Caroline, although he claimed he had not intended to murder her. He told the court he had placed cotton wool in her mouth to stop her screaming, a claim the judges rejected as they considered the full circumstances of the attack.
‘It is very clear to me that the asphyxiation was significant and harsh,’ a forensic policeman investigating Caroline’s death told reporters. ‘She stopped breathing very quickly.’
In June 2004, Francisco Arce Montes was found guilty of rape and murder and sentenced to 30 years in prison.
