Angel Cosio Sr., 47, and Angel Cosio Jr., 14., a father and son, were shot Aug. 22, 1998, near the entrance to a garbanzo bean field about 100 yards from Highway 101 in Nipomo.
Detectives believe Angel Cosio Sr. fired a small-caliber handgun during the altercation and may have shot the car or the suspects. The dark-colored sport coupe thought to have been used by the suspects in the killing has not been located.
