The jury decided that Kareem Montrell Tillar should spend 34 years in prison for second-degree murder after 19-year-old Jamel Cobb’s shooting death in September 2011.
Additionally, Tillar will serve a mandatory 5-year sentence for a related firearms conviction.
Tillar is scheduled for be formally sentenced on March 2.
Sources said detectives believe the shooting was sparked by a Facebook birthday greeting for a girl posted by Cobb, saying he wished he could do something more to celebrate. That angered the girl’s boyfriend.
Cobb was later in the 2100 block of Newbourne Street in Richmond
