Delilah graduated from Belleville High School in 2020 and was studying psychology at William Paterson University, her obituary says.
A GoFundMe in Delilah's memory launched by Ramon Espinol had raised more than $11,000 as of June 1.
Delilah was honored with a lantern-release ceremony last weekend.
BOE member Frank Velez remembered her as "force of positivity and joy," on a post from the ceremony.
"Delilah was a beautiful person & it was a beautiful sight to see the community come together for such a special soul."
Delilah's obituary remembers her for her "angelic smile and natural artistic abilities."
