MINNEAPOLIS — A Minnesota man was being held on a murder charge Monday after authorities said he brought a synthetic drug to a party that killed one teenager and sent 10 others to the hospital.

Timothy Richard Lamere, 21, of Blaine, was charged with unintentional third-degree murder in the death of Trevor Vance Robinson-Davis, 19. Prosecutors say Lamere caused the death by providing him with a synthetic substance called 2C-E.

The complaint filed in Anoka County District Court said Lamere arrived at a party in Blaine with a bottle containing a substance that he said would cause hallucinations. Witnesses told police Lamere offered the drug to anyone who wanted it and that he poured it onto a table and divided it into lines.

Witnesses told police Lamere inhaled the drug, as did Robinson-Davis. The complaint said Robinson-Davis began punching walls and yelling, then appeared to stop breathing.

Preliminary autopsy results show Robinson-Davis died of cardiac arrest due to the toxicity of the drugs. He had no pre-existing natural disease that would explain his death, the complaint said.

Everyone who inhaled or ingested the drug appeared to have adverse side effects. When officers first arrived, they found a group of young people, ages 16 through 21, having trouble breathing. Some appeared to be hallucinating.

Officials say 2C-E is a synthetic drug that can be bought online. It is a “cousin drug” to a banned rave-party drug. Sometimes known as “Europa,” 2C-E is not specifically listed as a “Schedule I” controlled substance, but a related substance known as 2C-B has been formally banned, and officials say the law allows for prosecution for “analogue” drugs.
