Apparently the truck was stolen on Wednesday at noon at the O'Reilly's in Clairemont (San Diego) by an employee named Malachi Hernandez, who was on the clock when he stole the vehicle (so stupid!!). The vehicle was spotted shortly thereafter driving North on Interstate 15 thru Fallbrook. There had been rumors that the truck was in the Perris area but the exact location was not known.
On Thursday afternoon / Friday morning, rumors were circulating that the truck had been spotted in the Palomar Mountain / La Jolla Indian Reservation area, but the theif's location has yet to be determined. So be on the lookout.
