A K9 deputy conducted a traffic stop along Interstate 10 at mile marker 215 for a minor traffic violation.

Canevet was driving the car and Lopez was the passenger, Forghani said. Deputies noticed Lopez appeared to be hiding something underneath her shirt. Deputies found eight bundles of heroin taped to her torso and chest, said Forghani.

"You never know what a simple traffic stop turns into and I applaud our deputies for preventing these drugs from hitting our streets and hurting more people, said Sheriff Mark Lamb.
