The backstory:

Police responded just before 6 p.m. Saturday to reports of gunfire in the parking lot and bus loop area of the Lidl in the 10300 block of Little Patuxent Parkway. Officers found two teenage victims suffering from gunshot wounds.

Michael Robertson, 16, of Columbia, was pronounced dead at the scene. Blake McCray, 15, also of Columbia, was rushed to the University of Maryland Shock Trauma Center, where he remains in critical condition.

Investigators believe Zeah specifically targeted the victims, though the motive remains unclear. 

A firearm and the clothing Zeah allegedly wore during the shooting were recovered from his residence, police said.

Authorities continue to investigate the circumstances surrounding the attack.
