A group of Montreal ravers became convinced that a man they had seen at a party was operating a local sex and drug trafficking ring after taking too much LSD and examining his Facebook profile. Although they saw him once, they never spoke or socialized with him and have never encountered him outside that party. They nevertheless say the large number of photographs showing him at restaurants with different women is extremely suspicious. "Nobody knows that many girls," says amateur investigator and psytrance promoter Cassandra Moonbeam. "Not without having some kind of business arrangement."

The investigation began at an afterparty when one of the ravers recognized the man in photographs posted by a mutual Facebook contact. By then, the group had swallowed several tabs of acid, smoked large amounts of marijuana and abandoned any plans to sleep. "Every time we scrolled down, there was another restaurant and another girl," says Cassandra. "Either he owns the city's most successful escort agency or he's incredibly sociable. Which one sounds more realistic?"

The group spent nine hours cataloguing the women and trying to determine their positions in the alleged operation. While heavily hallucinating, they classified several of the women as "underage strippers" and became convinced they were being moved between nightclubs. "Some of them looked extremely young," says Tyler Bassface, who admits he was on his fourth tab of LSD and that the faces on the screen had begun melting together. "That made identifying them difficult, but it also made the danger obvious."

The ravers believe the type of restaurant identifies which drug is being sold. Parmesan-covered pasta meant cocaine. "Nobody puts that much white powder on food unless they're sending a message," says Cassandra. Sushi meant ketamine. "Japan has cat cafés and catgirls, and vets give cats ketamine," says Tyler. "Connect the dots." The group became even more suspicious when one woman waited an entire week before commenting, "Thanks for dinner, I had a great time." "That isn't a thank-you," says Cassandra. "That's a delivery confirmation."

The man says the photographs are ordinary pictures taken during nights out and denies being involved in any criminal organization. "I have no idea who these ravers are," he says. "They've never spoken to me and now they're warning people that I run a sex and drug ring." Montreal police declined to investigate after learning that the evidence consisted entirely of restaurant photographs interpreted by people experiencing an LSD-induced psychosis. "Eating dinner with women is not a crime," says Sgt. Leonard Baptiste. "Neither is ordering Parmesan."

The following afternoon, several members of the group admitted that the LSD, marijuana and lack of sleep might have affected their investigation. Cassandra refuses to abandon the case. "Everyone keeps blaming the drugs," she says. "But LSD didn't invent those restaurant pictures. It just helped us understand what they mean."
