Éric Daudelin stands trial 20 years after Joleil Campeau murder

The case went cold for more than a decade, but now a man is standing trial in relation to the 1995 murder of JoleilCampeau.

Éric Daudelin appeared in a Laval courtroom on Monday to stand trial for three charges: first-degree murder, sexual assault and forcible confinement.

He pleaded not guilty to all three charges.

Cold case

In June 1995, Campeau left home to visit a friend who lived nearby — but she never arrived.

Police and neighbours scoured the woods near her house.

Four days later, her body was found.

Police concluded the nine-year-old was murdered, but it took 16 years to make an arrest.

Police had a suspect in June 2011 thanks to new DNA technology.

Trial to last for weeks

The Crown’s first witness was a retired police officer, who showed pictures of Campeau’s body when she was found — buried in mud in a creek near her house.

It’s also expected that the Crown will show a video of Daudelin speaking with undercover officers, who posed as criminals to gain his trust.

“As far as I am concerned, it's a technique of that goes against the Charter — goes against the criminal code … It gives a bad reputation. It takes away credibility if your client wants to testify,” said defence lawyer GillesDaudelin.

The judge warned the jury of six men and six women that the trial, which could last until the end of the month, could become emotional and draining.
