WENN 1 / 11

Bobby Brown canceled his appearance at the Charleston Jam Fest concert in North Charleston, South Carolina on March 4, just hours after his late daughter Bobbi Kristina Brown's cause of death was released on what would have been her 23rd birthday.

The 47-year-old was slated to perform with Keith Sweat, Jagged Edge and 112 at the concert, but according to signs on the doors of the North Charleston Coliseum, the "My Prerogative" performer pulled out "due to illness."

Earlier in the day, the autopsy of Bobby Brown and Whitney Houston's late daughter went public. The music man gave a statement to Us Weekly after the news hit, saying, "Kris will always live in my heart and soul." The mourning father added, "I love my baby girl. 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."

According to the Fulton County Medical Examiner's office, Bobbi Kristina died as a result of drowning and drug intoxication.

The statement from the medical examiner read, "The cause of Bobbi Kristina Brown's death as determined by the Fulton County Medical Examiner is: Lobar pneumonia. Due to: Hypoxic ischemic encephalopathy, delayed effects. Due to: Immersion of face in water complicating mixed drug intoxication."

The statement went on to detail that the drugs involved in her system were marijuana, alcohol, benzoylecgonine (a cocaine-related substance), benzodiazepines (medications used for sedation or to treat anxiety) and morphine.

The ME's office also added, "It could not be determined from toxicology tests whether the morphine resulted from heroin use."

Much like her mother, Bobbi Kristina was found unresponsive in a bathtub in her home in Roswell, Georgia on Jan. 31, 2015. She remained in a medically induced coma and was moved to hospice care for six months until her death on July 26, 2015 in Duluth, Georgia.
