A report about Darren Wilson, the police officer responsible for the fatal shooting of Michael Brown in Ferguson, Missouri, in August, has emerged.

Wilson told investigators that he struggled with the teenager over his gun. The New York Times reported that officer Wilson said he was in fear for his life as he was pinned against his vehicle by Brown.

The officer told government officials that during the scuffle with Brown, the young man reached for the gun. Forensics tests found that the firearm went off twice in the car, one bullet struck Brown in the arm while the second shot missed. Forensic analysis also found Brown's blood on the gun, interior door panel of the car and on Wilson's uniform.

Officer Wilson had told the investigating police officers that Brown had punched and scratched him several times, causing cuts and swelling on his face and neck.

This account of the events leading up to Brown's death is the first public account from Wilson. However, it does not explain what caused the officer to fire at Brown multiple times after he got out of the vehicle. Brown suffered a total of six gunshot wounds.

A few witness accounts contradict Wilson's story, furthering the outcry of anger and activism that has been stirring in Ferguson following the black teenager's death.

Wilson appeared for four hours before a St. Louis County grand jury in September, a jury who were called to decide if there is probable cause that the police officer committed a crime. The decision for Wilson to testify himself was surprising to many people, considering it is not required by law.

The struggle Wilson described may be influential information to a jury, as it helps illuminate Wilson's state of mind at the time of Brown's death, particularly his vulnerability and fearfulness before shooting the unarmed man.

Police officers have significant leniency when using lethal force if they believe they are in danger, according to The New York Times.
