His death was confirmed by Roseann Paradiso Fodera, an attorney and relative. Fusco's mother, Grace Fusco, died Wednesday night, hours after another son, Carmine Fusco, died in Pennsylvania.
A sister, Rita Fusco-Jackson, died last Friday. In her final hours, Grace Fusco wasn't aware her two children had died, Paradiso Fodera, told the newspaper.
Carmine Fusco died Wednesday at a hospital in northeastern Pennsylvania, where he lived. A sister confirmed his death, which was the first in Pennsylvania caused by the virus, to the Morning Call of Allentown.
Carmine Fusco and Rita Fusco-Jackson, who were both in their 50s, were "the most wonderful brother and sister that anybody can have," their sister, Andriana Fusco, told the newspaper. "They were good people. I don't know why this is happening. They didn't deserve this, they're too young."
A GoFundMe created for the family says six members of the family members were hospitalized with "severe symptoms" on March 10. "The Fusco family needs your thoughts and prayers during these hard times and any amount of donation would be greatly appreciated," organizer Allen Zak wrote.
Carmine Fusco trained horses that competed at harness racing tracks in the area. Andriana Fusco told The Morning Call that she disputed reports that the virus may have been spread through a family gathering attended by a person who'd had contact with 69-year-old John Brennan, a former harness racing trainer who worked for years at New York's Yonkers Raceway.
Brennan lived in northern New Jersey and was the first person in the state to die because of the virus, on March 10.
Andriana Fusco told the newspaper her brother Carmine hadn't been in New Jersey in the past two weeks and that she hadn't seen him since last month. She also said other members of her family had been sickened by the virus.
"God rest their souls," New Jersey Gov. Phil Murphy said about the family.
Murphy revealed during his Thursday media briefing that there are 318 new cases, bringing the state-wide total to 742, including nine deaths, CBS New York reported. Three of the state's nine deaths have been in Bergen County, including a 30-year-old man. The county alone has about 200 cases of COVID-19.
