DOVER, Del. — More than 35 years after the infamous suicide-murder of some 900 people – many forced to drink a cyanide-laced grape punch – in Jonestown, Guyana, the cremated remains of nine of the victims were found in a dilapidated former funeral home in Delaware, officials said Thursday.

The discovery brought back memories of a tragedy that killed hundreds of children and a U.S. congressman and horrified Americans.

The remains were clearly marked, with the names of the deceased and place of their death included on accompanying death certificates, authorities said. Kimberly Chandler, spokeswoman for the Delaware Division of Forensic Science, declined to release the names of the nine people to The Associated Press. She said officials were working to notify relatives.

She said the agency found the remains July 30 on a site visit prompted by a call from the property’s current owner – a bank, according to Dover police and public records. Officials found 38 containers of remains, 33 of which were marked and identified. Chandler said the containers spanned a period from about 1970 to the 1990s and included the remains from Jonestown, established by Peoples Temple leader Jim Jones.

“It’s simply a case of unclaimed cremains at a closed funeral home,” Chandler said, adding that there is no reason to believe the five unmarked containers contain remains of more Jonestown victims.

Jones ran the Peoples Temple in San Francisco in the early 1970s. He founded a free health clinic and a drug rehabilitation program. But allegations of wrongdoing mounted, and Jones moved the settlement to Guyana, the only English-speaking country in South America.
