Keenan Anderson, cousin of BLM co-founder Patrisse Cullors, died because of cocaine and an enlarged heart ... according to the coroner's office, which was investigating his death following a controversial LAPD arrest.
Body cam footage of Anderson's arrest sparked protests in L.A. earlier this year -- LAPD officers had used a taser on him for 42 seconds, according to Cullors. However, the L.A. County Coroner's autopsy report, released Friday, says Anderson's cause of death might have been the effects of cocaine use on his enlarged heart.
The report notes that a manner of death has not yet been determined.
The police video showed officers tasering Anderson -- who had been a high school English teach -- at least 6 times while he was on his stomach.
In response to Anderson's death, LAPD Chief Michael Moore said the department would be taking a closer look at taser deployment.
Patrisse told us, on "TMZ Live," she was deeply concerned about taser use, and said there's some alarming data about the effects of such high voltage on the human body.
