A Washington County man accused of killing a 9-year-old boy by standing in the street and firing randomly at passing cars has been found competent to stand trial.
Investigators say Nhan Tran went on a shooting rampage Feb. 11, 2013, around 6 p.m. just a few yards from his Oakdale home.
According to the criminal complaint, Tran used a 9mm handgun to indiscriminately fire at cars passing by him. In his jacket pockets, police found numerous 9mm bullets and loaded magazines. He also had two large knives in his backpack in protective sheaths.
Fourth-grader Devin Aryal died in the shootings, and his mother and another woman were wounded. Two other motorists escaped as they were being fired upon, the complaint said.
Tran told investigators he did it because people had been waking him up by revving their engines in front of his home, according to a search warrant affidavit.
In the affidavit Tran said "cars had been following him around for a while, and the persons driving the cars had been revving up their engines while parked in front of his house waking him up."
One mental evaluation found Tran to be incompetent to stand trial on six felonies, including murder and attempted murder. A competency evaluation determines the ability of the defendant to understand and rationally participate in the court process.
The judge ordered another evaluation from a different psychologist, which Tran has passed, KSTP learned Friday.
His trial is scheduled to begin Oct. 14.
