Whitney Houston's daughter's cause of death confirmed

The daughter of Whitney Houston, 22-year-old Bobbi Kristina, died on July 26 last year and her cause of death has now been confirmed.

Bobbi Kristina was discovered face down in a bathtub at her home on January 31, 2015 and following a nearly seven month-long coma, she was pronounced dead while in hospice care in July. She was laid to rest alongside her late mother at Fairview Cemetery in Westfield, New Jersey.

A statement has now been released from the Fulton County Medical Examiner, which explains that Bobbi Kristina died from Lobar pneumonia, which was caused by 'Hypoxic ischemic encephalopathy and water immersion combined with mixed drug intoxication'. Hypoxic ischemic encephalopathy is a form of brain damage caused by oxygen loss and it is one of the most common kinds.

Her report confirms traces of "marijuana, alcohol, benzoylecgonine (a cocaine-related substance), benzodiazepines (medications used for sedation or to treat anxiety), and morphine. It could not be determined from toxicology tests whether the morphine resulted from heroin use."
