A gas station robbery in Ukiah takes a serious turn after a suspect allegedly threatened to shoot an employee. Deputies say 37-year-old Joseph Mendoza argued with a clerk, acted like he had a weapon, and walked out with stolen items. Investigators tracked him down using surveillance video and arrested him later that same day. They say many of the stolen items were found at his home. Mendoza is now facing multiple charges, including robbery and violating probation.
