Jonathan attended Don Bosco Technical High School in Paterson, and later Bergen County Community College.
More than $9,200 had been raised in Jonathan's memory on a GoFundMe as of Nov. 8.
He was being remembered for his heart and caring nature.
"A guy who was always willing to help, have a good time, and would do anything for his friends and loved ones," said Gloria Udrija.
"Jon is a special person, and will always be remembered for his caring way," Darelene Noe said.
He is survived by his mom Mary Pettway and dad Walter Kowalczyk; step-dad Eldrige Pettway and Krystyna Kowalczyk; siblings Lauryn Dillard; Michelle Kowalczyk and Eriq Tyler Pettway; grandparents Irene and Peter Mlynaryk; uncle Mark Mlynaryk; girlfriend Yaribeth Reyes and countless friends.
Services were held at the Kugler Community Home for Funerals last month.
