A judge sentenced 22-year-old Hector Trejo, and 20-year-old Manuel Villanueva, to life without parole.
Jurors determined they killed two 16-year-old boys in April of 2009.
Prosecutors say the victims were together on a bicycle -- when Trejo and Villanueva approached them in a truck, and Trejo shot them.
A former Reedley gang member turned informant wore a wire and recorded their confessions. He's also a key witness in several upcoming murder cases.
