Police report arriving at Sunswept Apartment Complex (northeast of the intersection of Lindbergh and News Hall Ferry) around 11 p.m. October 27 and observing Green collapsed on the parking lot.
As the first officer administered first-aid, responding officers reported seeing two individuals running from the scene. The suspects -- identified as Grandberry and Brown -- were soon apprehended along with a handgun.
Police say it's unclear what relationship -- if any -- the teens had with Green, who was pronounced dead at an area hospital.
Grandberry, of the 4200 block of River Oaks Drive in north St. Louis County, and Brown of the 3100 block of Santiago, are each being held on a $200,000 bond.
