NORWALK — Norwalk Court Judge Dewey Falcone ruled Thursday that a 20-year-old Whittier man should spend 10 years in prison for shooting another man to death during a traffic dispute. Randy Aguila was found guilty Feb. 15 in the shooting of 26-year-old Oscar Rubio of Whittier in September 2005. A jury found him guilty of manslaughter, although prosecutors had charged Aguila with murder. The case against Aguila began when deputies stopped his car on suspicion of DUI, searched it and found an incriminating letter in which Aguila boasted about shooting a man. But his attorney argued that the shooting itself occurred after Aguila and Rubio squared off on a Whittier street, where Aguila had double-parked his car, blocking traffic. Rubio was returning to work after having had lunch at his home nearby. A verbal dispute broke out between the men, and Aguila opened fire on Rubio when he believed the other man was reaching for a gun, according to defense attorneys.
