EMS can’t transport a body. This is why people are declared dead at the hospital. If the person is declared dead at the scene, they have to be transported by either the ME or a funeral home.
My daughter is a paramedic and explained it to me when I asked the exact same question.
“EMS can’t transport a body.”
EMS here in TN transported my sister-in-law’s dead body. She might’ve bee officially declared dead at the hospital but was a goner 20 minutes before EMS even showed up.
