Michael Jackson's body was riddled with needle marks when he died, CNN and ABC News are reporting.

The multiple track marks and several collapsed veins -- discovered after Jackson's body was examined June 25 -- could indicate he was using a powerful sedative, Diprivan, at the time of his death.

On Larry King Live last night, Jackson's dermatologist (and alleged biological father to his two eldest children) admitted the singer had used the sedative, administered with an IV.

"I knew at one point that he was using Diprivan when he was on tour in Germany. And so he was using it, with an anesthesiologist, to go to sleep at night," Arnold Klein said. "And I told him he was absolutely insane. I said you have to understand that this drug, you can't repeatedly take. Because what happens with narcotics, no matter what you do, you build a tolerance to them."

Diprivan is usually used to induce unconsciousness in hospital patients before they undergo major surgery.
