Jurors on Monday found 37-year-old Donel Posten and 38-year-old Joe McNeely both guilty of second-degree murder in the death of Lionel "Ray" Fluker.
Poston and McNeely were also found guilty of attempted murder and being a felon in possession of a handgun. Each could receive life in prison at their sentencing on March 21.
The 54-year-old Fluker was a passerby caught in the felons' crossfire when he was struck while driving home in East Oakland in April 5, 2013.
Investigators determined the bullet that killed Fluker came from the gun of McNeely, who was known as Anthony Lister at the time of his arrest.
Fluker took freelance photos for the Tribune from 1995 to 2007.
