Olivia Rotondo, 20, of North Providence died at the Electronic Music Festival in New York City over the weekend. The cause of her death has not been officially determined, but city officials say it appears to have involved the popular drug MDMA, better known as Estacy, or Molly.
"They [users] believe it's not harmful or addictive and there wouldn't be any adverse side effects. Unfortunately, there can be many," said Brad Garrett ABC News' Crime and Terrorism Analyst.
The designer drug has been grabbing headlines. Police in Boston are investigating suspected drug overdoses. Several happened at a concert at the Bank of America Pavilion Saturday night. Three men in their 20's were taken to area hospitals after getting sick. They apparently took Molly. And just days ago at Boston's House of Blues another person died and two others were hospitalized after apparently using the drug.
Molly is a highly potent powered form of MDMA, one of the ingredients found in Estacy pills. It's been making waves in the club scene and on college campus', but experts warn that using it is not safe.
"They don't know what's in it. They don't know how much to use. It's a big risk," said Garrett.
A second concertgoer, Jeffrey Russ, 24, of Rochester, N. Y. also died at the festival. At least four other fell critically ill.
