Spookland sex assault investigations on hold due to lack of evidence

The investigations into three separate allegations of sexual assault at the Spookland Halloween party in west Quebec are on hold, police say, due to a lack of evidence and suspects.

About 1,000 people attended the private party at Mont Cascades on Friday, Oct. 31. It was a licensed event with five DJs and three dance floors aimed at people between the ages of 16 and 21. Attendees were bused in from Ottawa and eastern Ontario towns such as Carleton Place, Kemptville and Perth.

Nine people were taken to hospital from the party for either drug use or alcohol poisoning.

The following day, three separate girls who attended the event made sexual assault allegations to police. 

Two girls, 16 and 17, told police they were touched inappropriately while they were standing in line. The girls could not make out their assailants, no descriptions were available and no witnesses or suspects have come forward, said MRC des Collines-de-l'Outaouais spokesman Const. Martin Fournel.

Another girl, 16, was found by a female security guard surrounded by people. She was intoxicated and had ingested a date rape drug on a bus while en route to the event, Fournel said.

A rape kit test was performed and the results show she wasn't raped, Fournel said.

'At this point we're relying on the public,' police say

She may have been touched inappropriately, but the girl has no recollection of what happened and no witnesses have come forward, Fournel said. There is only a partial description of a suspect, he added.

"Was she touched inappropriately? Probably, but at this moment we don't have any suspect, any name, any description. Obviously there were lots of people there and it was hard to get more information about that specific case," Fournel said.

"At this point we're relying on the public to give us a call and give us some more information so we can start to investigate again."

Some of the people who attended the event have not co-operated with police. 

Police initially thought the girl was missing some of her clothes, but the investigation revealed that no clothes were missing.

An investigation into the liquor license for the event was done by police and the results have been forwarded to the province for evaluation to determine if charges or fines will be laid.
