MARSHALL — A Lynd resident and former administrator in the Marshall Public School District pleaded guilty to theft charges this week, court records said.

Michelle Noriega, 52 was given a misdemeanor sentence with probation conditions including community service work.

Noriega appeared in Lyon County District Court on Tuesday for a plea hearing, court records said. A criminal complaint said Noriega purchased items at Walmart in Marshall for less than the items’ actual price, by removing bar code stickers from merchandise in the store and putting the stickers on different items. The complaint said Noriega made purchases on several days and paid, in total, about $548 less than she should have for the items.

Noriega pleaded guilty to one charge of theft. A charge of theft by swindle was dismissed, court records said.

Court records said Noriega received a misdemeanor sentence for the charge. A sentence of 90 days in jail was stayed. Noriega also received a $400 fine, and one year of supervised probation with conditions including completing 100 hours of community service work, not entering Walmart in Marshall, and paying restitution.

Noriega was formerly assistant principal at Marshall Area Technical and Educational Center (MATEC). In August, the Marshall School Board approved Noriega’s resignation as assistant principal and teacher.
