Michael Jackson's arms were covered with puncture marks, his face and neck were scarred, and he had tattooed eyebrows and lips, but he wasn't the sickly skeleton of a man portrayed by tabloids, according to his autopsy report obtained by The Associated Press.

The Los Angeles County coroner's report shows Jackson was a fairly healthy 50-year-old before he died of a drug overdose. His 136 pounds (62 kilograms) were in the acceptable range for a five-foot-nine (1.72 metres) man. His heart was strong with no sign of plaque buildup. And his kidneys and most other major organs were normal.

Still, Jackson had health issues: arthritis in the lower spine and some fingers, and mild plaque buildup in his leg arteries. Most serious was his lungs, which the autopsy report said were chronically inflamed and had reduced capacity that might have left him short of breath.

But according to the document, the lung condition was not serious enough to be a direct or contributing cause of death.

"His overall health was fine," said Dr. Zeev Kain, chairman of the anesthesiology department at the University of California, Irvine, who reviewed a copy of the autopsy report for The Associated Press. "The results are within normal limits."

Kain was not involved in the autopsy. The full autopsy report has not been released publicly, but The AP obtained a copy.

Jackson died at his rented Los Angeles mansion June 25 after his personal physician, Dr. Conrad Murray, administered the anesthetic propofol and two other sedatives to get the chronic insomniac to sleep, court documents state. Propofol, normally a surgical anesthetic used in operating rooms, acts as a respiratory depressant and requires constant monitoring.

The coroner's office announced last month that Jackson's death was a homicide caused by "acute propofol intoxication," with other sedatives listed as a contributing factor. They said the standard of care for administering propofol was not met and the recommended equipment for patient monitoring, precision dosing and resuscitation was missing.

Murray is the target of what Los Angeles police term a manslaughter investigation. The decision on criminal charges will come from the Los Angeles County district attorney's office. Murray has been interviewed twice by police.
