Don't you hate it when you pay some sketchy dude for ketamine and he gives you Molly instead?

Aug. 31 proved a busy night for the EMTs hired to staff the Bank of America Pavilion: Over 3 1/2 hours, three people had to be taken away in ambulances with drug overdoses.

When a police detective asked one of them where he got the Molly ER doctors at Tufts Medical Center said he'd taken too much of, the guy replied he didn't know it was Molly. Seems a long-haired white guy with glasses just came up to him at his seat in Section 5 shortly before 10 p.m. and offered to sell him some ketamaine - an offer he accepted. Who knew you couldn't trust strangers at an STS9 show?

The detective and officials from the pavilion testified yesterday before the Boston Licensing Board on three apparently unrelated overdoses at the Aug. 31 concert by STS9 and Umphrey's McGee. The board decides Thursday whether the pavilion did anything wrong.

Pavillion officials said they were surprised by the problems, because STS9 and opening act Umphrey's McGee were not known for inspiring the sort of drug-filled misadventures certain other acts have been blamed for. They said they always staff concerts with EMTs and security to deal with any problems.

Sgt. Det. Kenneth O'Brien said he doesn't think the venue could have done anything differently - drug users are going to find ways to drug it up, especially when you have things like Molly pills the size of small Aspirin tablets.

O'Brien recounted what he was able to learn about the events leading up to the overdoses - for some reason, he said, the victims have proven reluctant to talk to police.

In the second case, which happened about ten minutes after the ketamine/Molly mixup, EMTs transported a man to Mass. General with an apparent LSD overdose. O'Brien said he's been unable to learn more - the man lives in North Attleborough and has not responded to requests for an interview.

Earlier in the evening, around 6:40 p.m., EMTs transported a third man to Tufts Medical Center. He claimed he downed five or six cheap draft beers, then went into a men's room, where some guy offered him $30 worth of Molly in a men's room, which he says he took - and then blacked out until regaining consciousness in the emergency room. He was unable to even say where in the pavilion the men's room was, but said it had wooden floors.

Bank of America Pavillion officials, however, said his story simply didn't hold up. The pavilion doesn't have any men's rooms with wooden floors and it would have been near impossible for him to down five or six beers in the four minutes between the time his ticket was scanned and the time he was found semi-comatose. Plus: "No one has ever called our draft beer cheap," manager Jim Jensen said.
