The loss of 22-year-old Andrew Quinn, the Parsippany Hills High School and Cornell University graduate killed early Saturday after being struck by a vehicle driven by a still-unknown motorist on New York City's West Side Highway, is a difficult one for those who loved him.

Many have taken to social media to recall a man who, according to his brother Jeff Quinn, who told NJ.com, "He excelled in all areas."

One old friend posted a photo of her and Quinn from third grade on Instagram with a caption: "Thank you for everything you did for me during our wonderful friendship. You will never be forgotten. RIP Andrew"

Other remembrances appeared on Twitter:

• RIP Andrew Quinn, you were a wonderful person and you will be greatly missed.
• Literally feels like yesterday we were playing basketball together. RIP Andrew Quinn. 
• I only met you once or twice but RIP to Andrew Quinn, how tragic; such a brilliant mind taken much too early.
• The entire #Cornell family sends our thoughts to the family of Andrew Quinn '12, an alumnus who we lost far too soon

Quinn served as president of Par Hills' senior class in 2008. His Legacy.com obituary recalls he was also a talented musician who performed in a number of championship marching bands and was named an all-state saxophone player. He was chosen to participate in the Hugh O'Brien World Conference, a leadership training event.

Interested in sports as well, Quinn was involved in track and field, performing in the disciplines of high hurdles, javelin and high jump. Skiing was another of his passions.

As a high schooler,  Quinn showed commitment to his community by volunteering as a firefighter for the Mt. Tabor Fire Department.

Ultimately, he entered the field of real estate, landing a position as an analyst for Tishman Realty in New York, where he'd recently moved.

Quinn is survived by his parents, John Quinn and Linda Quinn; his brother, Jeff; his sisters, Dr. Colleen Sears and her husband Rob, and Kathleen Quinn; his paternal grandmother, Grace Quinn; and his niece, Ella.

A private funeral and cremation were held this week with arrangements handled by the Par-Troy Funeral Home.

A memorial fund in Quinn's honor has been set up to give an annual scholarship a deserving Parsippany Hills High senior band member.
