The family of former YouTube CEO Susan Wojcicki has experienced a devastating loss.

The businesswoman’s son, Marco Troper, was discovered dead at the University of California, Berkeley, on February 13. He was nineteen.

A university spokeswoman informed NBC News that a student living in a student housing complex was discovered unconscious that day, and that first responders from the Berkeley Fire Department performed life-saving efforts before declaring him dead. There were no evidence of foul play, and the death was being investigated, according to the spokeswoman.

Marco’s grandma, Esther Wojcicki, confirmed the student’s identification.

“Tragedy hit my family yesterday. My beloved grandson Marco Troper, age 19 passed away yesterday,” she wrote on Facebook on Feb. 14. “Our family is devastated beyond comprehension.”

Marco, she added, “was the most kind, loving, smart, fun and beautiful human being” who had just begun his second semester of his freshman year at UC Berkeley. She noted he majored in math and “was truly loving it.”

“He had a strong community of friends from his dorm at Stern Hall and his fraternity Zeta Psi and was thriving academically. At home, he would tell us endless stories of his life and friends at Berkeley,” she continued. “Marco’s life was cut too short. And we are all devastated, thinking about all the opportunities and life experiences that he will miss and we will miss together. Marco, we all love you and miss you more than you will ever know.”

Campus police at UC Berkeley said that there were no evidence of foul play.

Adam Ratliff, a UC Berkeley spokesman, said counselors set up “healing spaces” for students to deal with the victim’s tragic death.

Wojcicki, who presently works as a senior advisor for Google and its parent company Alphabet, has yet to speak publicly on her son’s death.
