Michael Brown, the unarmed black teen who was killed by a white police officer in Ferguson, Mo., in August, was shot in the hand at close range and had marijuana in his system, an autopsy report by the St. Louis County Medical Examiner's Office concludes.

The St. Louis Post-Dispatch published the report on its website. Suzanne McCune, administrator for the county medical examiner, acknowledged that the report was accurate, but said that the office did not release it to the newspaper.

The county report in some ways differs from the autopsy conducted at the request of Brown's family, which concluded the shots were fired from at least a foot away and as far as 30 feet away.

The county reports says a preliminary investigation indicates Brown became "belligerent" with officer Darren Wilson after Wilson asked him to stop walking in the street. The report says Wilson attempted to get out of his patrol car and that Brown, 18, pushed the door shut "and began to struggle with Officer Wilson."

The report says the gun went off during the struggle and that Brown fled. Wilson gave chase, the report said, and opened fire when Brown turned and started running back toward the officer.

Brown's family says the officer attempted to pull Brown into the patrol car and that the teen was killed when, after fleeing, he turned around and raised his hands to surrender.

Michael Graham, who is medical examiner for the city of St. Louis and is not part of the official investigation, reviewed the autopsy report and said it "does support that there was a significant altercation at the car."

The county autopsy report indicates a shot traveled from the tip of Brown's right thumb toward his wrist. The report says there is no stipple — powder burns around a wound that indicate a shot fired at relatively short range. But Graham told the newspaper that stipple does not always appear "when it's really close, such as within an inch or so."

The county report does indicate that the thumb wound contained "foreign particulate matter ... consistent with products that are discharged from the barrel of a firearm."

Judy Melinek, a forensic pathologist in San Francisco, told the newspaper the autopsy indicates Brown was "reaching for the gun, if he has gunpowder particulate material in the wound." She added, "If he has his hand near the gun when it goes off, he's going for the officer's gun."

Pathologist Michael Baden, who conducted the autopsy requested by the family, concluded that bullet wounds to Brown's arms could have been sustained by putting his hands up or crossing his arms.

Last week, The New York Times reported that Wilson told investigators that he was pinned in his vehicle and in fear for his life as he struggled for control of the gun. The Times, citing government officials briefed on the federal civil rights investigation, said Wilson told the authorities that Brown reached for the gun, that it was fired twice in the car, and that the first bullet struck Brown in the arm while the second bullet missed.

Wilson told the authorities that Brown punched and scratched him repeatedly, leaving swelling on his face and cuts on his neck, the Times said.

That description of events conflicts with the description offered by Dorian Johnson, who was with Brown when the shooting took place. Johnson said Wilson was the aggressor, grabbing Brown by the neck, choking him and then grabbing Brown's arm to pull him into the car.

Johnson said Wilson pulled out his gun and shot Brown. Johnson said the men then fled but stopped when ordered to do so, and that Brown was shot when he turned around to surrender.

The shooting set off weeks of unrest in the predominantly black community outside St. Louis. A grand jury is hearing the case and will decide whether to charge Wilson with Brown's death.
