The first stop happened at around 8:22 a.m. on eastbound I-40 eight miles northeast of the city. The trooper conducted a search and found 376-pounds of cocaine, 40-pounds of meth and two firearms in the semi. A 2011 Dodge 3500 truck and over $44-hundred dollars were also seized. The driver and passenger, who are father and son, where arrested and booked into the Navajo County Jail on drug charges. Then at around 6:37 p.m., troopers pulled over another semi-truck four miles west of Holbrook. Following a positive alert from a Sheriff’s K9, a search found nearly 12-pounds of cocaine. The driver, 42-year-old Damiano Rowe of Fontana, California was arrested and booked on drug charges.
