Prince was in grave danger, doctor appointed to save his life a day before death

A recent video shows that a doctor was appointed to save Prince's life a day before he died.

The video shows of Dr. Howard Kornfeld, arriving at his Marin County, CA rehab facility, Recovery Without Walls, reports TMZ.com.

Reportedly, a representative for Prince called the doctor, who is not speaking up anything now, saying the singer was in grave danger and the doctor's services were desperately needed.

Dr. Kornfeld could not immediately clear his schedule, but he sent his son, who came with a synthetic opiate used to treat people with addiction problems.
