Tevin had been excused from a school assembly Jan. 30 to go to the bathroom. When he didn't return, a male teacher went looking for him. He found Tevin caught on a hook by his shirt. The boy died at the hospital two days later.
Police said the shirt collar had cut off his oxygen. They also considered suicide or homicide but found no evidence to support either possibility.
An attorney for Tevin's parents said he had "lingering questions" about the boy's death.
"It just doesn't make sense the way that they have described it based on the physical evidence," attorney Dan Ross told the Austin American-Statesman.
