The Woodland Elementary School Principal who is accused of abusing a special needs third-grader earlier this year is pleading “not guilty” to three counts of fourth-degree assault. Mark Houk was in Cowlitz County District Court yesterday, where he entered the plea in connection with allegations made in March. In paperwork filed yesterday, it’s claimed that Houk “sharply grabbed” the 9 year-old by the shoulders during one incident; he’s also accused of pushing the boy into a cabinet, and of knocking his glasses across the room. Police statements also quote school staff as saying that Houk allegedly restrained the student for more than 20 minutes during an incident in January, and for 13 minutes during an incident in October. Staff members also report on other incidents that took place in 2003 and 2004. Houk was arrested on April 17th, and is free after posting bail. A jury trial is currently scheduled for July 21st.
