On Thursday, the New York City medical examiner’s office confirmed to Nexstar that it had ruled Burrell died by suicide. Her death was labeled as “acute intoxication” from the antihistamines diphenhydramine and cetirizine; ethanol, which can be found in alcohol; and amphetamine, which can be used to treat ADHD.

Burrell's cause of death was “acute intoxication” due to the combined effects of multiple substances, the New York City Medical Examiner Office said.
