A 44-year-old woman died and two others remain in critical condition after they apparently overdosed on GHB, an illegal party drug, police said.
Emergency workers were called to a home in Venice Beach just before dawn Sunday.
The call was made by a fourth person, said Margaret Stewart, a spokeswoman for the Los Angeles Fire Department. That person declined medical treatment, she said.
The 44-year-old woman was already in cardiac arrest when the paramedics entered the home, Stewart said. She was rushed to a hospital, where she later died.
