Three people are accused of stealing $50,000 worth of electronics from the downtown Microsoft store over a period of four months.

Multnomah County District Attorney Rod Underhill announced Thursday that police focused on the Microsoft store after employees reported thefts multiple times recently. The employees said that tablets and laptops were the primary items taken.

Through monitoring of the store and responding to 911 calls, police made three arrests.

Seth Wyatt Colson is charged with first-degree theft; Michael Duane Shepherd is charged with two counts of aggravated theft in the first degree and computer crime; and Natalie Nicole Pence is charged with aggravated theft in the first degree and computer crime.

According to the district attorney’s office, Portland police caught Shepherd in the act while they monitored the store.

Police say Shepherd walked in, took a laptop and left. The district attorney’s office says Shepherd has taken electronics at least 28 times, worth a collective value of more than $20,000.

Colson was arrested after store employees called police about a stolen laptop. He is suspected of stealing items on Nov. 26 and Nov. 29.

Pence is also accused of stealing $10,000 worth of merchandise over several visits in November.
