The same day she was sworn into service, Clark-Vancouver Regional Drug Task Force drug detection dog Piper helped nab one of the task force’s largest drug seizures to date, according to the Clark County Sheriff’s Office.

Sheriff’s deputies, task force officers, and the Multnomah County Special Investigations Unit arrested three people and seized more than 25 pounds of heroin, methamphetamine and cocaine, $220,000 in cash, guns and two cars Wednesday evening, the sheriff’s office said.

Investigators received word Wednesday that Miguel Trujeque Magna, 32, and Juana Santiago Santos, 23, both of Mexico, would be traveling north of Vancouver to buy drugs, according to the sheriff’s office.

Officers followed the two north to the Seattle area, where they met with Luciano Molina Rios, 45, also of Mexico, and allegedly observed the three counting money and making some kind of transaction.

The three drove two cars back to Clark County, and deputies pulled the three over as they passed the Northeast 179th Street exit along Interstate 5. There, deputies reported, they found 2 pounds of heroin and arrested the three.
