The mother of a 16-year-old girl who died after overdosing on Ecstasy at a house party last year is suing the homeowner and the teens who were with her the night she died.

Catherine Korpinen filed the lawsuit in Middlesex Superior Court this week, charging homeowners Eugene and Cynthia Singer and three teenagers with negligence, The Middletown Press reported.

Korpinen's daughter, Makayla, took the club drug at the Singer home on May 17, police said, and died four days later of multiple organ failure and acute renal failure.

The suit charges the teens did not seek medical help immediately after Makayla began having seizures. The Singers are charged with not providing a safe, drug-free home.

Following her daughter's death, Korpinen also filed a notice of intent to sue the town of East Hampton, on the grounds that the police department did not do enough to find and return Makayla, who reportedly had run away from home.

Korpinen was scheduled to testify next week before the state Judiciary Committee on a bill that would give parents more power to force authorities to return runaway teens to their homes.

Researchers at The Johns Hopkins University demonstrated that 4 days of exposure to the drug caused damage that persisted 6 to 7 years later.

Some pills sold as ecstasy actually contain little or no MDMA. Pills may contain other drugs such as PMA or another MDMA analogue, DXM, household chemicals such as Ajax or rat poison, or other (sometimes lethal) byproducts.

The Federal penalty for manufacturing or selling ecstasy can lead to fines up to four million dollars. A ringleader or head manufacturer of ecstasy could receive life in prison.

Memory tests of people who have taken Ecstasy as compared to non-drug users have shown that the Ecstasy users had lower scores.
