A coroner has revealed that Bobbi Kristina Brown’s death was caused by a combination of being immersed in water and having marijuana, alcohol, morphine and other drugs in her system, which led to pneumonia.
Also said the official statement:
Death was clearly not due to natural causes, but the medical examiner has not been able to determine whether death was due to intentional or accidental causes, and has therefore classified the manner of death as undetermined.
