The charge was lowered to one count of luring, a class E felony. Judge Daniel Stahnke sentenced him.Stahnke accepted the sentence recommended by the defense, citing evidence that Lown has a low risk to reoffend and no criminal history. There was also no actual victim in the crime.Lown starting speaking with a Renton police officer in October 2011 on Yahoo! chats, under the belief the officer was a young girl. The chats eventually escalated to a sexual nature, leading the Renton officer to contact Vancouver police that March.Members of the Vancouver Police Digital Evidence Cybercrimes Unit served a search warrant at Lown’s residence in the 1700 block of Northeast 94th Street, where they seized several pieces of evidence.
