Jerry Sun, a class of 2023 Wharton undergraduate student and TA for Wharton summer programs, was killed in a car accident west of Cañon City, Colorado, on July 25 while he was on a hiking trip. The crash is under investigation, and alcohol and speed are not factors in the accident. He was 19.

At the time of the accident he was living in College Point, New York; at Penn, he lived in Speakman, Ware College House. Mr. Sun was a member of Cohort Rand. He was active in the Wharton Management Club, Wharton Private Equity and Venture Capital Club, Wharton Real Estate Club, and Wharton Giving Society. For the last two months, he worked as a TA with high school students in Wharton summer programs.

“Jerry brought happiness and laughter with him wherever he went,” his family said in a statement. “His curiosity was insatiable and his spirit was unbreakable. He was selfless in his desire to help others and a source of comfort in times of distress. He was incredibly gifted but humble, a quick learner but perpetually diligent. He was an aspiring entrepreneur, loyal friend, and beloved son.”

“Jerry took to teaching immediately, and his students took to him just as quickly,” noted Eli Lesser, executive director of the Wharton Global Youth Program. “We are heartbroken to think of Jerry not being part of our program and our community.”

Mr. Sun is survived by his parents and his sister.
