loss and cardiac arrest. During the third hour after the shooting, an autopsy was performed due to overwhelming media interest. It revealed that the bullet had entered Selena's upper right back, near her shoulder blade, passed through her chest cavity, severed the right subclavian artery, and exited her right upper chest. It took minutes from the point of impact of the bullet that Selena lost "virtually all the blood in her body" which contributed to her rapidly bleeding to death. Doctors said that if the bullet had been only one millimeter higher or lower, the wound would have been less severe.
