Gregory's death was first announced by his sister Rebecca Hertzberg-Pfaffinger in a July 10 Facebook post.

"It is with a heavy heart my family has suffered a loss way too early," Hertzberg-Pfaffinger wrote alongside photos of Gregory with their family.

She continued, "Ben was a great Son, Brother and Uncle. He was fun to be around and made us laugh quite often. Still, going through his things, I find myself laughing at little videos or notes of his, in between crying."
