Michael Brown’s blood found on Darren Wilson’s gun

According to forensic evidence, Michael Brown’s blood was found on the gun, uniform and inside the car of Ferguson police officer Darren Wilson, law enforcement officials told the Washington Post.

Authorities believe the forensic evidence potentially corroborate Darren Wilson’s story that the unarmed 18-year-old tried to take his gun.

The evidence will make it harder for the Justice Department to prosecute Officer Darren Wilson on federal charges that he violated Michael Brown’s civil rights, said the officials.

Such evidence would also make it difficult for a county grand jury to indict Darren Wilson on state charges, such as murder or manslaughter, said county sources who also are prohibited from talking on the record about the pending case.

The St. Louis County police, the FBI and a county grand jury are investigating the shooting. The Justice Department is investigating Ferguson and St. Louis County policing practices and whether they have violated the rights of residents.

Darren Wilson, who is white, fatally shot Michael Brown, an African American, on August 9 in the majority black St. Louis suburb of Ferguson.
