The author applies the insights derived from studies of family processes, especially those relevant to suicide, to the mass suicides &/or murders in Guyana. Family characteristics of suicidal behaviour also found at Jonestown were: 1) a closed family system; 2) domination of the family by a fragile member; 3) an atmosphere of depression & aggression; 4) a symbiosis lacking in empathy; 5) secretiveness; & 6) suicide as a pattern of behaviour learned within the family.
