A 23-year-old man previously convicted of killing a Columbia teen outside the Wilde Lake Village Center in 2008 pleaded guilty to first-degree murder and a gun charge Monday in the retrial of the case in Howard County Circuit Court.
Kirwan said Tucker called the crime "completely senseless," and Wilson apologized in court Monday morning to Adams' mother for not showing enough regret during the first trial.
According to testimony in the case, Wilson was at the then-Crown gas station in Wilde Lake around 11 a.m. on April 9, 2008, when he got into an argument with Adams and his two friends.
Wilson, who was 19 at the time, said he was "disrespected" by Adams and his two friends and left the gas station.
Minutes later, Adams' friends testified that Wilson, who had changed his clothes, returned to the area with a handgun and shot Adams four times, twice while he was on the ground.
Before the incident, Wilson had never met Adams or his two friends, according to the two friends and Wilson.
In Wilson's original trial, the handgun used in the murder was not submitted into evidence because it had not been found.
During opening statements last week, Nelson said the gun, which originally was purchased in Augusta, Ga., was linked to Wilson, who had moved to Columbia from the Augusta area weeks prior to Adams' death.
