Ferguson Police Chief Thomas Jackson says the officer who shot and killed unarmed black teenager Michael Brown last Saturday is Darren Wilson, a six-year veteran of the force who has no disciplinary actions on his record with the department.

The release of Wilson’s name comes after Jackson said he wouldn’t identify the man out of concerns for his safety, citing death threats made to Ferguson police and on social media. Jackson said that Wilson was treated for injuries he sustained Saturday.

Before he released the name, Jackson also discussed a robbery that had occurred shortly before Brown’s death on Aug. 9. He said that police were releasing footage and records related to that robbery, responding to “sunshine” requests for public information.

While Chief Jackson didn’t directly link Brown to the robbery at a convenience store, the police materials released Friday mention Brown by name, along with another man named Dorian Johnson.

The report of a strong-arm robbery is in a packet of materials police released today. It includes a transcription of surveillance video from the store, in which Brown and Johnson are described entering the store and picking up a box of Swisher Sweet cigars.
