NBC:

“State officials believe the family’s deaths are connected to John Brennan, 69, a horse trainer from Bergen County who was the first person to die from the coronavirus in New Jersey.”

(Unfortunately this is not the same John Brennan who as CIA director backed al Qaeda in Syria for 5 years, made up the Russiagate hoax and who definitely deserves to drown in his own fluids. But we can still hold out hope.)
