The Washoe County School District Police Department is revealing more details about the arrest of a teacher at Hug High School in Sparks. Ryley Coker is accused of offering a 16-year-old boy, a student, 500 dollars in exchange for sexual favors. Investigators say the 32-year-old gave the student his personal cell phone number after a discussion about improving his grade. Coker then allegedly sent him explicit text messages. Coker, who was arrested last Thursday, is suspended without pay.
