The Huffington Post reporter Ryan Reilly said the report identifies Brown as the primary suspect in the robbery and tweeted photos of some pages in the report.
Julie Bosman, a correspondent for The New York Times, said Wilson is a six-year veteran of the force with no history of disciplinary action.
Jackson confirmed that report and also said Wilson was treated for injuries after the incident.
The nation has erupted in outrage and taken to the streets in largely peaceful protests since the fatal confrontation. For days, images coming out of the St. Louis suburb presented a harrowing picture of unrest as police fired tear gas and rubber bullets at protesters and placed demonstrators and journalists under arrest.
The climate has changed drastically since Thursday, when President Barack Obama condemned authorities' use of excessive force and Missouri Gov. Jay Nixon (D) called in the state's highway patrol to take over supervision of the suburb.
Police said Brown, 18, was shot multiple times Saturday after being confronted by a white officer. The FBI opened an investigation into Brown's death on Monday. Authorities initially offered vague details about the confrontation but said the officer involved had been placed on administrative leave.
