Bobby Brown Jr., the son of singer Bobby Brown Sr., passed away last year due to the “combined effects of alcohol, cocaine and fentanyl,” according to an autopsy report released by the Los Angeles County Coroner on Monday (March 22).

The 15-page autopsy report said that ”no drugs or drug paraphernalia” were found at the Los Angeles residence where Brown Jr. was found dead on Nov. 18, reports TMZ. A witness reportedly told police he had downed tequila and snorted Percocet and cocaine. His death is listed as accidental.

The 28-year-old was one of Brown Sr.’s seven children. Kim Ward, his mother, and his father were on and off for 11 years.

In the days leading up to Brown Jr.’s tragic passing, his family said he was not feeling well and was experiencing flu-like symptoms. However, they didn’t believe he had COVID-19.

“Please keep my family in your prayers at this time,” Brown Sr. previously said in a statement to People. “Losing my son at this point in our lives has devastated my family. There are no words to explain the pain.”

Landon Brown previously shared a throwback video with his late brother to Instagram on Nov. 19. In the clip, the two siblings sang Justin Bieber’s “Love Yourself” song in a car. He captioned the post, “Everything hurts King.”

Brown Jr. is the second child that Brown Sr. has lost. Bobbi Kristina, his daughter that he shared with the late Whitney Houston, tragically passed away in 2015. The 22-year-old drowned in a bathtub and had “toxic levels of cocaine and alcohol in her system,” reports TMZ. She was in a coma for several months until her family decided to take her off life support.

Kristina’s death was eerily similar to her mother’s passing. Houston was found unconscious in a bathtub after an accidental drug overdose just three years before her daughter died.
