SKAGIT COUNTY, Wash. — A sex sting operation in Skagit County netted two men police said were trying to have sex with underage girls.One of the men volunteered at an Oak Harbor Elementary School.The parents of children at Hillcrest Elementary received an email from the superintendent, informing them about the arrest of a volunteer who spent a very limited amount of time at the school and didn’t have the opportunity to be alone with children.That man is accused of communication with a minor for immoral purposes, attempted rape of a child and commercial sexual abuse of a minor.The arrests were the result of a sting operation set up by the Skagit County Sheriff’s Office. A 46-year-old detective went undercover online, posing as 13 -or 14-year-old girls to see whether any men would solicit them for sex.“I stress they made the contact. We didn’t pursue them. They made contact with us,” said Skagit County Sheriff Will Reichardt.Last Thursday, they arrested a 64-year-old Oak Harbor man, Jonathen Kruze, as he waited for a 13-year-old girl to show up at a picnic table outside a gas station, officer said. Police said Kruze had offered to pay $100 for a sex act. A few hours later, a Concrete man was arrested in Lion’s Park under similar circumstances.“They took the bait, so to speak,” said Reichardt.The Oak Harbor School District said Kruze volunteered at Hillcrest about 20 hours a year. When they found out about the arrest, they revoked his volunteer badge and banned him from school property.When KIRO 7 Eyewitness News reporter Chris Legeros went to Kruze’ address Wednesday afternoon, he found a man spreading bark outside who ran into the house and shut the door. When he rang the doorbell and asked him if he had anything to say about the accusations, he yelled, “if you don’t leave, I’ll dial 911.”The Sheriff’s Office said Kruze does not have a criminal history, so nothing showed up when the district did a criminal background check on him like it does with all volunteers.
