Just over a week ago, Marco Troper, the 19-year-old son of former YouTube CEO Susan Wojcicki, died in his Berkeley dorm room after taking a drug. 

“We don’t know what was in it,” his grandmother Esther Wojcicki told local media. “Teenagers and college students need to know that drugs today are not the same as the drugs of yesterday. They’re often laced with fentanyl.”

His family are waiting on the results of a toxicology report, which could take up to a month. But if it’s true that Marco lost his life to fentanyl, one thing is clear: he did not die of an overdose. 

He was poisoned.
