Bobbi Kristina Brown's cause of death was revealed on March 4, 2016.
The daughter of the late Whitney Houston and Bobby Brown died as a result of drowning and drug intoxication, the Fulton County Medical Examiner's office determined.
"The cause of Bobbi Kristina Brown's death as determined by the Fulton County Medical Examiner is: Lobar pneumonia," the statement from the examiner's office read. "Due to: Hypoxic ischemic encephalopathy, delayed effects. Due to: Immersion of face in water complicating mixed drug intoxication."
It goes on to say that the drugs involved in her system at the time included marijuana, alcohol, benzoylecgonine (a cocaine-related substance), benzodiazepines (medications used for sedation or to treat anxiety) and morphine.
The medical examiner's office added, "It could not be determined from toxicology tests whether the morphine resulted from heroin use."
Bobbi Kristina was found unresponsive in a bathtub in Roswell, Georgia on Jan. 31, 2015. She remained in a medically induced coma and was moved to hospice care for six months.
In May 2015, Bobbi Kristina's grandmother Cissy Houston spoke about her granddaughter's condition to Entertainment Tonight. "She's the same, she's not progressing at all," Cissy said. "She's not gone yet, but you know, whatever the Lord decides, I'm ready for her...I have nothing to do with that. That's His job. It's His territory, you know? And I understand it."
Bobbi Kristina passed away at age of 22 on July 26, 2015.
She was buried beside her mother on Aug. 3, 2015, and her autopsy results were sealed that September.
Whitney died of accidental drowning on Feb. 11, 2012. The effects of heart disease and cocaine use contributed to her death.
Bobbi Kristina's autopsy results were released on the same day that would have been her 23rd birthday.
In a statement given to PEOPLE on March 4, her father responded to the news of her autopsy being released.
"First and foremost, 23 years ago today, Bobbi Kristina was born," Bobby said. "Krissy will always live in my heart and soul. I love my baby girl."
He continued, "For news affiliates to seek and obtain my daughter's autopsy report, before anyone has been brought to justice for her death is mind blowing to me. Please pray for my family."
