A man and his 2-year-old nephew have been struck and killed by a pick-up truck while walking near their home in Bloomington. Authorities identified them as 27-year-old Pedro Guerrero and his nephew, Alejandro Guerrero. The McLean County coroner says they were walking Thursday evening with their dog when they were hit by the truck. The dog was also killed. First responders found the man and his nephew unresponsive on opposite sides of Old Colonial Road. The boy was in a stroller. A preliminary investigation indicates poor lighting may have played a role.
