According to a coroner’s report, the 28-year-old died of an overdose of alcohol, cocaine and the powerful opioid fentanyl.
He died at his Los Angeles home on November 18, 2020, after being found to be unresponsive in his bedroom by his girlfriend, Anna Reed.
According to BBC, Anna called the paramedics, who declared him dead, with no foul play suspected.
The autopsy report released on Monday referred to his death as an accident, as the musician had a history of drug and alcohol usage.
The family stated that Bobby Brown Jr. was experiencing flu-like symptoms at the time but had not tested positive for Covid-19.
Bobby Brown Jr. was one of the two children from Bobby Brown’s 11-year relationship with Kim Ward, which ended in 1991.
He died eight years after his stepmother, Whitney Houston, accidentally drowned in a bath, and five years after his 22-year-old half-sister, Bobbi Kristina, died in similar circumstances.
Last November, Bobby Brown said: “His son’s death had devastated my family, and there were no words to explain the pain.”
Bobby Brown Jr.’s brother, Landon, paid tribute by sharing a black-and-white photo of his late sibling on Instagram, alongside the caption: “I love you forever King.”
The musician’s girlfriend, Anna Reed, tweeted: “The heavens gained an angel but I lost my soulmate.”
