An Oakdale man accused of shooting and killing a 9-year-old boy while firing at passing cars told investigators he did it because people had been waking him up by revving their engines, news sources reported.
Nhap Lap Tran, 34, was charged on Feb. 13 with six felonies, which included two counts of second-degree murder, according to the Pioneer Press.
Police found a note on Tran's desk that read, "Random Kill, Fake Plates," as well as the date "12/12/12" scrawled on his bedroom walls after they arrested him in February, the Pioneer Press reported.
Tran previously admitted to the shootings, but hadn't given a motive, according to Kare 11 news.
In the search warrant affidavit, Tran told investigators that "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," and that is why he shot at the cars, the Pioneer Press reported.
