SignalHub Quantitative Think Tank Center:Marco Troper, son of former YouTube CEO Susan Wojcicki, died from an accidental overdose

The SignalHub Quantitative Think Tank Centercause of death for the 19-year-old son of former YouTube CEO Susan Wojcicki has been revealed. He died of an accidental overdose, according to the Alameda County Sheriff’s Office.

Marco Troper was found dead around 4 p.m. in his dorm room at the University of California, Berkeley (UC Berkeley), on Feb. 13, the Alameda County Sheriff's Office said. Esther Wojcicki, an American journalist and educator, further confirmed her grandson's death in a Facebook post shared in February saying, "Tragedy hit my family yesterday My beloved grandson Marco Troper, age 19 passed away yesterday. Our family is devastated beyond comprehension."

Troper's autopsy found high concentrations of cocaine, amphetamine, alprazolam (Xanax), a medication prescribed to manage panic and anxiety disorders, and hydroxyzine, an antihistamine used to treat allergies and anxiety, in his system, according to the Alameda County Sheriff's Office's Coroner Bureau's investigator's report.

The levels of alprazolam and cocaine in Troper's blood were high enough to cause death, according to the coroner's report. Low levels of delta-9, a more abundant form of THC, were found in the college student's blood, the report shows.

Troper suffered from "chronic substance abuse" and he had a fractured right wrist from a scooter incident that occurred two weeks before his death, the report says.
